A week of pleasantly cool temperatures to start March included the coldest day of the winter to date in the high country on Saturday 7th (the air and windchill temperatures I recorded at San Jacinto Peak that morning were -12°C and -26°C, respectively).

Unfortunately temperatures were so high in the last eight days of February that the modest snow accumulation – it feels like an exaggeration to use the word snowpack – had already been largely removed. Nevertheless the cooler weather did slow snowmelt rates, and perhaps more importantly established tracks in the high country remained firm and have been a genuine joy for hiking, with easy barebooting on ascents, and no more than spikes needed for descending.

Sadly this recent hint of seasonal winter temperatures is ending, and forecasts for the middle two weeks of March make for astonishingly grim reading. Temperatures rapidly climb to far above seasonal by Thursday 12th, then threaten to be genuine midsummer temperatures, likely shattering myriad March records, from Sunday 15th until Friday 20th at least. Obviously melting of what little snow remains will be dramatic, and if the forecasts prove to be accurate, the mountain may be largely snow-free by late March.

Spikes remain recommended for most trails above about 8000 ft (lower in places) for the foreseeable future as established tracks are so well consolidated by hiker traffic. As tracks rapidly melt over the next two weeks they will become (briefly) become more slippery.

Snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow several feet deep may be much easier hiking than traversing across just a few inches depth of angled virgin icy snow.

The USFS gate at Humber Park reopened on 1st March. The gate 1.7 miles up from Highway 243 on Black Mountain Road (4S01) remains closed. Following superficial grading late in 2025 the road is in better condition than last summer, but remains far rougher than in June 2020, the last time it was thoroughly graded. South Ridge Road (5S11) reopened on 3rd March and is clear of snow.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically 2-3 times per week (but almost daily during winter storm weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures rise dramatically starting 11th March, plateau at well above seasonal on 12th-14th, before rising even further, genuinely close to midsummer averages (overnight lows especially), on 16th-20th. Several daily high temperature records may be broken in the region during that period, and the all-time March record high for San Jacinto Peak could be shattered, which also happened in February this year (anyone else sense a trend here?).

With such a pronounced high pressure system stationed over Southern California, unsurprisingly there is no significant new precipitation in the forecasts.

Three snow storms in very quick succession impacted the region across four days on 16th-19th February, with the consequent snowfalls described in detail in a prior Report (linked here). Temperatures rose dramatically starting immediately after the passage of the last storm system, and were far above seasonal throughout the last week of February, before then cooling closer to seasonal in the first nine days of March. The latter was associated with the brief passage of a minor “cutoff” low pressure system on 6th-8th March, with accompanying strong winds and cold temperatures in the high country.

At San Jacinto Peak (10,810 ft/3295 m) on Monday 9th March 2026 at 0855 [DST] the air temperature was 28.7°F (-2°C), with a windchill temperature of 8.4°F (-13°C), 33% relative humidity, and a stiff ENE wind sustained at 25 mph gusting to 35.6 mph.

At the Peak on Saturday 7th March 2026 at 0820 the air temperature was 10.6°F (-12°C), with a windchill temperature of -14.8°F (-26°C), 71% relative humidity, and a frigid NNE wind sustained at 16 mph gusting to 30.0 mph. Both the air and windchill temperatures were the lowest recorded at the Peak (so far) in winter 2025/26.

At the Peak on Thursday 5th March 2026 at 0840 the air temperature was 31.9°F (0°C), with a windchill temperature of 17.8°F (-8°C), 16% relative humidity, and a variable NW wind sustained at 7 mph gusting to 16.0 mph.

TRAIL CONDITIONS

Trails above about 9700 ft remain at least 90% snow-covered, and most have significant snow cover above 8600 ft (west side) or 9000 ft (east side). Most routes below 8600 ft are now largely clear of snow, and completely clear below 7500 ft (details for specific trails below, where known).

Please consider that with temperatures rising dramatically over the next ten days, snow even at the highest elevations will not refreeze overnight, and melting will be remarkably fast and widespread, changing trail conditions almost daily.

Carrying spikes is recommended for the foreseeable future everywhere above about 8000 ft even as snow softens and melts dramatically over the next week or two, as established trails are now so consolidated by hiker traffic and weeks of freeze-thaw cycles.

Neither crampons nor snowshoes are required anywhere on the established trail system at this time. In theory snowshoes could be of value over the next couple of weeks as snow will soften so rapidly (and not refreeze) with temperatures remaining above freezing even at the highest elevations. However snow depths are already minimal, even in many off-trail areas, and melting of what little remains will be very rapid into late March.

Hikers interested in more comparison photos of the trails from immediately after the previous fresh snowfall in late February, and the conditions 7-10 days later, will find these in the previous Report (available here).

Current snow cover on the PCT is minimal from Miles 151 (Highway 74) to about 175 (Red Tahquitz), largely confined to thin patches on the east slope of Spitler Peak (Mile 168) and the northerly aspects of Apache Peak (Mile 169.5), both areas that can be easily worked around. Some of the minor chutes in Miles 170-173 have tricky icy snow, but this will soften dramatically in the next couple of days. Snow cover is 90% between Miles 175-177. Snow cover is thin and averages 80% between Miles 177 to 179, then only 10% to Mile 180.5, but about 90% just south of Annie’s Junction at about Mile 180.8. Miles 181-183 average 20% snow cover. Snow cover is almost continuous from Mile 184 to 185.5, although spikes are not required on the well-traveled snow track. There are no visible tracks at this time on the Fuller Ridge Trail section (Miles 185.5 to 191.5), although snow is thin and increasingly patchy, especially on the sun-exposed parts of that trail. Tracks should be in place in the next couple of days. Stubborn sections remain around the crossing of the North Fork of the San Jacinto River (Mile 186), and on the northerly slopes (approx. Miles 187.5-187.8 and 188.6-190.4). North of Mile 191, the trail is functionally clear of snow.

Carrying spikes remains strongly recommended for PCT hikers throughout the San Jacinto mountains at this time, although they are not essential for those hikers who (a) remain on the PCT and do not take the alternate route via San Jacinto Peak, and (b) have a high comfort level and considerable experience of hiking on patchy icy snow without traction devices.

The 0.4 mile section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [surveyed 3rd March] currently has only a very lightly-traveled single posthole track to follow through steeply angled icy snow (photo below). The snow is becoming more patchy, and melting will be rapid this week, nevertheless these icy slopes on the north side of Tahquitz Peak are notoriously treacherous. Currently spikes (or preferably crampons) with an ice axe, and the requisite physical and mental skills to use this equipment in high angle terrain, are strongly recommended, but even then this section of trail will not be a comfortable option for most hikers until there is further melting and snow starts to soften over the next few days.

Devil’s Slide Trail [surveyed 9th March] is completely clear of snow to 7700 ft, and functionally clear from there to Saddle Junction. Persisting minor patches of icy snow are so small and dirty that they do not require spikes at this time.

Wellman Trail [surveyed 9th March] has a moderately-traveled and often uneven posthole track through about 70% snow cover.

The Peak Trail [surveyed 9th March] has been well-traveled, although in places around 10,000 ft the most heavily traveled track does not accurately follow the trail route. There is a well-compacted posthole and snowshoe route from Wellman Divide to about 10,000 ft through 90% snow cover. With a few bare patches already appearing this section of trail will clear rapidly this week. Above 10,000 ft, snow cover remains almost continuous, and the track becomes more uneven. Most traffic has followed the uppermost traverse of the Peak Trail to Summit Junction (meeting Deer Springs Trail). Multiple tracks around the Peak all ultimately reach the top, although none quite manage to accurately follow the established trail route.

A lightly-traveled, but now unfortunately rather lumpy posthole track broadly follows the East Ridge Trail route [surveyed 9th March] through almost continuous snow cover from near the Miller switchback (10,400 ft) to San Jacinto Peak, and is, as always, an excellent alternative to the uppermost Peak Trail.

The Round Valley Trail [surveyed 5th March] has a rapidly thinning 40% snow cover to Round Valley, and thereafter a well-traveled posthole track through 90% snow cover to Wellman Divide.

Deer Springs Trail [surveyed four times since 2nd, most recently on 9th March] is functionally clear of snow to Strawberry Junction. Snow cover then averages barely 10% for one mile north of Strawberry Junction, increasing to 40% closer to the junction with Marion Mountain Trail, but is only 1-3 inches deep in most places. Thereafter, snow cover on the trail is >90% to San Jacinto Peak, although with an increasing number of bare patches are starting to emerge in the most sun-exposed sections, even as high as 10,400 ft. The somewhat uneven posthole track is largely accurate to the trail route as far as Little Round Valley (LRV). The most heavily-traveled track through LRV vaguely approximates to the trail route, but then at least four tracks ascend from LRV, none of which follow the true trail route for any significant distance, and all of which climb steeply through icy snow toward the Peak, as is traditional in winter. These tracks will become harder to follow as melting increases, as they run through vegetation and boulders, by which time the actual trail route should become more evident.

Marion Mountain Trail [surveyed 7th March] is functionally clear of snow to about 7600 ft, and thereafter has a very well-defined track through largely continuous icy snow to its junction with Deer Springs Trail, that generally follows the true trail route. Icy snow cover is so thin that this trail will largely clear of snow in the next week. There is already one lengthy sun-exposed section at 8200-8400 ft that is now snow-free. Spikes can be useful, at least for descending the uppermost trail.

As of 7th March there were no visible tracks through the discontinuous snow on Seven Pines Trail or Fuller Ridge Trail (PCT Miles 185.5-190.5), although the latter has been traveled by both nobo and sobo PCT section hikers that I have encountered, largely when snow was too firm to leave obvious tracks.

Strawberry Trail (PCT Miles 181-183) [surveyed 6th March] averages 20% snow cover (example photo below).

South Ridge Trail to Tahquitz Peak [surveyed 3rd March] is functionally clear of snow to Old Lookout Flat (7600 ft). Thereafter there are a few small snow patches on the traverse to 7900 ft, snow cover increasing to 20% on the lower switchbacks, and then to 50% in the upper switchbacks closest to Tahquitz Peak. Snow is firm and icy in the early mornings, starting to soften and become “greasy” by about 0900 (but this will change dramatically during the course of this week). Many hikers may find spikes useful in the upper switchbacks but they are not essential for those most experienced on such terrain. Four new blowdowns that came down on this trail in the mid February storms have already been removed by the Trail Report (photo in the previous Report).

Spitler Peak Trail [surveyed 27th February] is functionally clear of snow. The Trail Report cleared another nine trees from the lower four miles of the trail, bringing to 183 the number of trees removed from this trail in recent years. Unfortunately the trail suffered major blowdowns in the most recent storm sequence and four large burned cedars are seriously obstructing the trail between 3.2-4.0 miles up from the trailhead. Several additional small trees remain uncut closer to the PCT.

Skyline Trail reopened on 4th March. Although it is largely clear of icy snow, some hikers may find spikes useful above 7200 ft (the “Traverse”).

SNOW DEPTHS

Snow depths measured on 9th March 2026 (unless indicated otherwise) are as follows. Current total depth is the principal number given, followed (in parentheses) by the greatest snow depth of this winter to date, following the storms of mid February. Altitudes and PCT mileages are approximate.

San Jacinto Peak (10810 ft): 6 inches (was 26 inches on 20th February), ranging from 0-14 inches, drifted deepest on east and north aspects, including East Ridge.

Little Round Valley (9750 ft): 6 inches (was 23 inches on 23rd February), ranging from 0-12 inches in places.

Wellman Divide (9700 ft): 1 inch (was 20 inches on 20th February).

Annie’s Junction/PCT Mile 181 (9020 ft): 4 inches (was 27 inches on 20th February).

Tahquitz Peak (8836 ft): 0 inch (was 23 inches on 21st February) immediately around the fire lookout, but 2-15 inches on adjacent trails [measured 3rd March].

Long Valley (8500 ft): 0 inch (was 14 inches on 20th February).

Strawberry Junction/PCT Mile 183 (8100 ft): 0 inch (was 15 inches on 23rd February).

Saddle Junction/PCT Mile 179 (8070 ft): 1 inch (was 22 inches on 20th February).

Devil’s Slide Trail trailhead at Humber Park (6500 ft): 0 inch (was 17 inches on 20th February).

Idyllwild (at 5550 ft): 0 inch (was 12.5 inches on 20th February).

The San Jacinto Trail Report celebrates ten years of operation in 2026. It is read by over 30,000 people each year, and will pass one million views in 2026. The Report has helped thousands of hikers, and saved multiple lives, both directly and indirectly. Since the Report became established online, snow/ice rescues in the San Jacinto Mountains have dropped 82%, also saving Riverside County tens, if not hundreds, of thousands of dollars. While all time is volunteered, the Report uses small private donations to help cover operating costs. Donations keep the Report available to all, free from advertising or paywalls, and independent from agencies. If you have found this Report useful, please consider using this link to the Donate page.

Temperatures were so high in the last eight days of February – with daily and monthly records being set throughout Southern California – that they remained above freezing overnight at even the highest mountain elevations. This resulted in snowmelt at an unprecedented rate, even more striking given that it was in the genuinely winter month of February, with Idyllwild losing 12 inches of snow in four days, sun-exposed locations above 9000 ft losing up to 20-22 inches in a week, and San Jacinto Peak also losing about 15 inches in just seven days.

Thankfully, temperatures cooled to near seasonal from Monday 2nd March, and are forecast to fluctuate either side of seasonal for most of the first two weeks of the month, which should be most noticeable in the high country. This should have two significant effects. First, snowmelt rates will slow markedly, and trail conditions may not change dramatically over the next week or more. Secondly, compacted snow tracks established in the high country will remain firm, at least until late morning, allowing for much easier hiking (with spikes now optimal for traction rather than snowshoes).

For example, snow was comfortably firm enough for barebooting all the way from Devil’s Slide Trail to San Jacinto Peak early in the morning on Monday 2nd and Thursday 5th, although on 2nd anywhere I stepped off the compacted posthole tracks I promptly sank ankle deep into surrounding snow. Snow remained firm until about 0930 on 2nd, by which time I was well down Deer Springs Trail and snow was so shallow and patchy that even spikes were no longer needed. This weekend will be colder, so hiking conditions should be even easier (with appropriate traction as needed), in stark contrast to the slop and snowshoes of much of last week.

Spikes are recommended for most trails above about 7600 ft for the foreseeable future as established tracks have now become consolidated by hiker traffic and will continue to undergo significant freeze-thaw cycles this week. Snow depths are currently suitable for snowshoeing only off-trail above about 9500 ft, possibly lower as snow softens by late morning on the warmest days and on the most sun-exposed slopes.

Snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow several feet deep may be much easier hiking than traversing across just a few inches depth of angled virgin icy snow.

The USFS gate at Humber Park reopened on 1st March. The gate 1.7 miles up from Highway 243 on Black Mountain Road (4S01) remains closed. Following superficial grading late in 2025 the road is in better condition than last summer, but remains far rougher than in June 2020, the last time it was thoroughly graded. South Ridge Road (5S11) reopened on 3rd March and is clear of snow.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically 2-3 times per week (but almost daily during winter storm weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Three snow storms in very quick succession impacted the region across four days on 16th-19th February, with the consequent snowfalls described in detail in a prior Report (linked here). Temperatures rose dramatically starting immediately after the passage of the last storm system, and were far above seasonal throughout the last week of February, as discussed above.

Temperatures are forecast to cool closer to seasonal in the first ten days of March, but with high pressure generally remaining in the region and mild, sunny days, steady snowmelt will continue, albeit at a slower rate than in late February. Forecasts indicate the brief passage of a minor low pressure system on 6th-8th March, with accompanying strong winds and cold temperatures in the high country.

At San Jacinto Peak (10,810 ft/3295 m) on Saturday 7th March 2026 at 0820 the air temperature was 10.6°F (-12°C), with a windchill temperature of -14.8°F (-26°C), 71% relative humidity, and a frigid NNE wind sustained at 16 mph gusting to 30.0 mph. Both the air and windchill temperatures were the lowest recorded at the Peak (so far) in winter 2025/26.

At the Peak on Thursday 5th March 2026 at 0840 the air temperature was 31.9°F (0°C), with a windchill temperature of 17.8°F (-7°C), 16% relative humidity, and a variable NW wind sustained at 7 mph gusting to 16.0 mph.

At the Peak on Monday 2nd March 2026 at 0810 the air temperature was 30.9°F (-1°C), with a windchill temperature of 13.3°F (-10°C), 38% relative humidity, and a stiff due West wind sustained at 16 mph gusting to 29.4 mph.

TRAIL CONDITIONS

Trails above about 9500 ft are completely snow-covered, and most have significant snow cover above 7600 ft, but routes below 7600 ft are now generally clear of snow (details for specific trails below, where known).

With high country temperatures near (or even below) freezing for most or all of the next two weeks, spikes are recommended for the foreseeable future everywhere above 7600 ft as snow generally firms up, especially overnight and in the mornings, along with localized icing, and as established trails have become increasingly consolidated by hiker traffic and undergo freeze-thaw cycles.

Crampons remain an option above about 9500 ft for the next week at least, especially in the morning when snow remains firm, but they are certainly not required anywhere on trail, and may result in significant postholing during off-trail travel.

Snowshoes are no longer recommended for travel on the established trail system, as tracks are now generally compacted, icy and uneven. However snowshoes would be invaluable for off-trail travel (e.g., to high peaks other than San Jac) as snow above 9000 ft away from the compacted tracks remains soft, especially after mid morning.

In prior winters I have mentioned the challenges of hard, icy snow underfoot and the value of using spikes especially for descending and traversing. Snow at all elevations will become increasingly firm and icy following multiple freeze-thaw cycles, and I cannot overemphasize the importance of having both appropriate equipment and the right skill set for the terrain. The latter includes interpreting the snow/ice conditions, understanding your physical and mental abilities, and conservative decision making. These concerns may steadily increase over the next couple of weeks with temperatures fluctuating either side of freezing, seasonally stronger insolation, and locally variable snowmelt.

Current snow cover on the PCT is minimal from Miles 151 (Highway 74) to about 175 (Red Tahquitz), largely confined to thin patches on the east slope of Spitler Peak (Mile 168) and the northerly aspects of Apache Peak (Mile 169.5). Snow cover is 90% between Miles 175-177. Snow cover is thin and averages 80% between Miles 177 to 179, then only 10% to Mile 180.5, but almost 100% just south of Annie’s Junction at about Mile 180.8. There are no tracks here where the PCT turns sharply to the west. Miles 181-183 average 20% snow cover. Snow cover is continuous from Mile 184 to 185.5, although spikes are not essential. There are no tracks at this time on the Fuller Ridge Trail section (Miles 185.5 to 191.5), although snow is thin and will be increasingly patchy on the sun-exposed parts of that trail. Stubborn sections will remain around the crossing of the North Fork of the San Jacinto River (Mile 186), and on the northerly slopes (approx. Miles 187.5-187.8 and 188.6-190.4). North of Mile 191, the trail is functionally clear of snow. Carrying spikes is recommended for PCT hikers throughout the San Jacinto mountains at this time.

The 0.4 mile section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [surveyed 3rd March] currently has only a very lightly-traveled single posthole track to follow through steeply angled icy snow (photo below). These icy slopes on the north side of Tahquitz Peak are notoriously treacherous. Currently spikes (or preferably crampons) with an ice axe, and the requisite physical and mental skills to use this equipment in high angle terrain, are strongly recommended, but even then this section of trail will not be comfortable for most hikers until it starts to soften late next week.

Ernie Maxwell Trail [surveyed 2nd March] is now functionally clear of snow (thank you to Anne and Anabel for that report).

Devil’s Slide Trail [surveyed 5th March] is already clear of snow to 7600 ft. From there to Saddle Junction snow cover averages only 20%. Spikes are useful, at least for descending, but they are not required for early morning ascending when the snow is firm, nor for hikers who are especially proficient on patchy icy snow.

Wellman Trail [surveyed 5th March] has a moderately-traveled and very uneven posthole track through about 60% snow cover.

The Peak Trail [surveyed 5th March] has been well-traveled, although in places around 10,000 ft the most heavily traveled track does not accurately follow the trail route. There is a well-compacted posthole and snowshoe route from Wellman Divide to about 10,000 ft through almost continuous snow, but with a few bare patches starting to appear. Above 10,000 ft, snow cover is continuous, and the track becomes more uneven. Most traffic has followed the uppermost traverse of the Peak Trail to Summit Junction (meeting Deer Springs Trail). Multiple tracks around the Peak all ultimately reach the top, although none manage to accurately follow the established trail route.

A lightly-traveled, but now unfortunately lumpy posthole track broadly follows the East Ridge Trail route from near the Miller switchback (10,400 ft) to San Jacinto Peak, and is, as always, an excellent alternative to the upper Peak Trail.

The Round Valley Trail [surveyed 5th March] has a rapidly thinning 40% snow cover to Round Valley, and thereafter a well-traveled posthole track through 90% snow cover to Wellman Divide.

Deer Springs Trail [surveyed 2nd, 6th, and 7th March] is functionally clear of snow to Strawberry Junction, with just a handful of tiny snow patches increasing in frequency closest to the junction. Snow cover then averages 30% until about 8500 ft (less than one mile south of the junction with Marion Mountain Trail, but is only 1-3 inches deep in most places. Thereafter, snow cover on the trail is functionally continuous to San Jacinto Peak, although a handful of bare patches are starting to emerge in the most sun-exposed sections, even as high as 10,400 ft. The somewhat uneven posthole track is largely accurate to the trail route as far as Little Round Valley (LRV). The most heavily-traveled track through LRV vaguely approximates to the trail route, but then at least four tracks ascend from LRV, none of which follow the true trail route for any significant distance, and all of which climb steeply through icy snow toward the Peak, as is traditional in winter.

Marion Mountain Trail [surveyed 7th March] is functionally clear of snow to about 7600 ft, and thereafter has a very well-defined track through largely continuous icy snow to its junction with Deer Springs Trail, that generally follows the true trail route. There is one lengthy sun-exposed section at 8200-8400 ft that is now snow-free. Spikes are valuable, at least for descending the uppermost trail.

As of 7th March there were no tracks through the discontinuous snow on Seven Pines Trail or Fuller Ridge Trail (PCT Miles 185.5-190.5).

Strawberry Trail (PCT Miles 181-183) [surveyed 6th March] averages 20% snow cover (example photo below).

South Ridge Trail to Tahquitz Peak [surveyed 3rd March] is almost completely clear of snow to Old Lookout Flat (7600 ft). Thereafter there is 10% coverage of small snow patches on the traverse to 7900 ft, increasing to 30% on the lower switchbacks, and then to 60% in the upper switchbacks closest to Tahquitz Peak. Snow is firm and icy in the early mornings, starting to soften and become “greasy” by about 0900. Most hikers will find spikes useful in the upper switchbacks but they are not essential for those most experienced on such terrain. Four new blowdowns that came down on this trail in the mid February storms have already been removed by the Trail Report (photo below).

Spitler Peak Trail [surveyed 27th February] is functionally clear of snow, with a few tiny patches of soft, thin snow remaining in the upper third of the trail. The Trail Report cleared another nine trees from the lower four miles of the trail, bringing to 183 the number of trees removed from this trail in recent years. Unfortunately the trail suffered major blowdowns in the most recent storm sequence and four large burned cedars are seriously obstructing the trail between 3.2-4.0 miles up from the trailhead. Several additional small trees remain uncut closer to the PCT.

Skyline Trail reopened on 4th March. Although it is largely clear of icy snow, some hikers will find spikes useful above 7200 ft (the “Traverse”).

SNOW DEPTHS

Snow depths measured on 2nd March 2026 (unless indicated otherwise) are as follows. Current total depth is the principal number given, followed (in parentheses) by the greatest snow depth of this winter to date, following the storms of mid February. Altitudes and PCT mileages are approximate.

San Jacinto Peak (10810 ft): 9 inches (was 26 inches on 20th February), drifted two feet deep in places, notably on east and north sides, especially East Ridge.

Little Round Valley (9750 ft): 8 inches (was 23 inches on 23rd February), ranging from 0-20 inches in places

Wellman Divide (9700 ft): 6 inches (was 20 inches on 20th February)

Annie’s Junction/PCT Mile 181 (9020 ft): 7 inches (was 27 inches on 20th February)

Tahquitz Peak (8836 ft): 0 inch (was 23 inches on 21st February) immediately around the fire lookout, but 3-15 inches on adjacent trails [measured 3rd March]

Long Valley (8500 ft): 1 inch (was 14 inches on 20th February)

Strawberry Junction/PCT Mile 183 (8100 ft): 0 inch (was 15 inches on 23rd February)

Saddle Junction/PCT Mile 179 (8070 ft): 2 inches (was 22 inches on 20th February)

Suicide Rock/Deer Springs trails junction (7000 ft): 0 inch (was 8 inches on 23rd February)

South Ridge Trail trailhead at top of South Ridge Road (6500 ft): 0 inch (was 16 inches on 21st February)

Devil’s Slide Trail trailhead at Humber Park (6500 ft): 0 inch (was 17 inches on 20th February)

Idyllwild (at 5550 ft): 0 inch (was 12.5 inches on 20th February)

Editorial note: although trail details in this Report were extensively revised on Monday 23rd February for many major routes, the rate of melting in the past 4-5 days has been literally unprecedented. Trails below 7000 ft have largely cleared of snow, with increasing patchiness of snow at all elevations. Temperatures are not expected to drop sufficiently to allow some firming of higher elevation snow until 2nd March.

With such a rapid rise in temperatures, snow conditions are changing on several time scales; weekly, daily, and even hourly. Well-prepared hikers will account for these changes. Underfoot conditions are already dramatically different now compared to 3-6 days ago, and will change even further over the course of the next few (unseasonably warm) days. Snow firm enough for barebooting (or spikes) early in the morning is turning into soft slop by mid morning, for which snowshoes are invaluable. This weekend snow at all elevations will be soft throughout the day, as overnight temperatures remain well above freezing even in the high country. Hikers unwilling to carry snowshoes must anticipate widespread and severe postholing.

Three snow storms in very quick succession impacted the region across four days on 16th-19th February. Although technically three separate storms, the impact on the mountain and trail system has functioned as one major storm, with the most substantial (so far) snowfall of winter 2025/26, especially at mid elevations.

Although the combined 26 inches of new snow around the highest peaks was desperately needed and is of course extremely welcome, this was at the lowest end of the forecast expectations, and hopes for 3-5 feet of snow were not ultimately realized.

I recorded a rather-too-lengthy video report from 10,350 ft on the east slope of San Jacinto Peak mid morning of Friday 20th February that summarizes the three storms and conditions at that time (linked here).

Snow fell in three distinct periods, on the afternoon and evening of Monday 16th, then again overnight on 17th-18th, followed by a much more minor snowfall on the evening of Thursday 19th. As was widely forecast this latest storm pattern was significantly colder than others so far this season, with freeze levels more typical of the historical average (at or below 5000 ft for much of the storm period). Consequently there was considerable snowfall at mid elevations, with the first snow of the winter recorded, for example, in Idyllwild (12.5 inches at 5550 ft across the four days), and with all three storms dusting down into Garner Valley (4400 ft).

As is increasingly the trend with a rapidly changing climate in recent years, there was relatively little difference in snowfall between the mid and upper elevations, with 12.5 inches measured in Idyllwild (at 5550 ft) through to 26 inches at San Jacinto Peak (10,810 ft). Locations on the western side of the mountain range, especially those in and around Strawberry Valley, received disproportionately more snowfall, as those areas were “socked in” by storms originating from the south-west, while the highest elevations were, at times, above the cloud.

Snow depths are currently ideal for snowshoeing everywhere above about 7000 ft at all times, lower as snow softens by mid morning (late morning in sheltered areas). Elsewhere, and in addition, spikes are recommended for the foreseeable future as established trails will eventually become consolidated by hiker traffic and will undergo freeze-thaw cycles.

Cautious navigation is strongly recommended everywhere. Even where well-traveled tracks are in place, they may not lead where you want to go (or not on the angle of terrain you would prefer to hike). As described below, some major trails have not yet been traveled at all, and that is unlikely to happen before next weekend at the earliest.

Snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow several feet deep may be much easier hiking than traversing across just a few inches depth of angled virgin icy snow.

The USFS gate at Humber Park closed on 18th February. While theoretically nine legal parking spaces remain immediately below the gate, an unconventional ploughing approach during these latest storms has left space for only 3-5 vehicles to safely park. Conditions in the area are very icy and currently only suitable for 4WD/AWD vehicles anyway, so this area is best avoided in the absence of further ploughing. Parking on Forest Drive, just below the Fern Valley Water District facility, is strongly recommended.

Black Mountain Road (4S01) is closed at the gate 1.7 miles up from Highway 243. Following superficial grading late in 2025 the road is in better condition than last summer, but remains far rougher than in June 2020, the last time it was thoroughly graded. South Ridge Road (5S11) closed due to winter conditions on 22nd February.

On 25th February, the state park closed the section of Skyline Trail under their administration (from 5600 ft to Grubb’s Notch). This is apparently due to “unsupportive snow” and “constant post-holing”. While hikers will be understandably upset at the state park for this poor decision, please also direct your ire at those hikers who are unprepared for the conditions – physically, mentally, or in terms of equipment – who consequently encourage the agencies to make such decisions.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically 2-3 times per week (but almost daily during winter storm weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures rise rapidly starting Friday 20th, and will be far above seasonal in the last week of February (likely record-breaking warmth on Friday 27th at all elevations). Temperatures are forecast to be above freezing >10,000 ft elevation for the remainder of the month, and with clear, sunny days expected, melting of snow will be very rapid, especially on sun-exposed slopes. Temperatures are tentatively forecast to cool closer to seasonal in the first week of March, but by then much of the damage (in terms of snowmelt) will have been done.

The storm system on 16th-19th February consisted of three distinct phases, with the majority of the snow in the high country in the first storm, overnight on 16th. At mid elevations, the first phase was mild enough to initially produce rain, with 0.57 inches in Idyllwild, before turning to snow around dusk on 16th. The second phase was overnight on 17th, with bulk of the high country snow actually falling in the early hours of Wednesday 18th (about half the depth of the previous day). Finally the third storm passed through on Thursday 19th, with much lighter snow falling throughout much of the day, from late morning until just after dusk.

At San Jacinto Peak (10,810 ft/3295 m) on Monday 23rd February 2026 at 0930 the air temperature was 41.7°F (5°C),with a windchill temperature of 33.3°F (1°C), 28% relative humidity, and a light WNW wind sustained at 6 mph gusting to 10.4 mph.

At the Peak on Friday 20th February 2026 at 0740 the air temperature was 17.8°F (-8°C),with a windchill temperature of -7.1°F (-22°C), 49% relative humidity, and a wild WNW wind sustained at 22 mph gusting to 36.2 mph.

At the Peak on Thursday 19th February 2026 at 1010 the air temperature was 15.3°F (-9°C), with a windchill temperature of -6.2°F (-21°C), 100% relative humidity, and a frigid WSW wind sustained at 14 mph gusting to 22.3 mph.

At the Peak on Tuesday 17th February 2026 at 0830 the air temperature was 11.0°F (-12°C), with a windchill temperature of -11.2°F (-24°C), 100% relative humidity, and a steady due West wind sustained at 18 mph gusting to 24.2 mph.

At the Peak on Monday 16th February 2026 at 1410 the air temperature was 23.9°F (-5°C), with a windchill temperature of 5.5 °F (-15°C), 100% relative humidity, and a subdued SW wind sustained at 12 mph gusting to 21.1 mph.

TRAIL CONDITIONS

All trails above about 6500 ft are completely snow-covered, and largely snow-covered above 5500 ft. By the afternoon of Friday 20th, melting was already well underway below 7000 ft, and by Monday 23rd, all elevations had already lost 2-4 inches of snow to melting.

Snowshoes are currently invaluable everywhere above about 9000 ft, and can be used as low as 6000 ft as snow softens dramatically by late morning, as long as depths remain sufficient at such low elevation (probably until later this week). Conversely, snowshoes are also invaluable in the most sheltered areas that have yet to experience freeze-thaw cycles and hence the snow is still relatively fresh powder (e.g., parts of upper Deer Springs Trail, and either side of Annie’s Junction/PCT Mile 181).

Elsewhere (and in addition), spikes are recommended for the foreseeable future everywhere above 6000 ft due to localized icing, and as established trails become increasingly consolidated by hiker traffic and undergo freeze-thaw cycles. Crampons are an option in the high country for the next few days, especially in the morning when snow remains firm, but warming is forecast to be so rapid that severe postholing will soon become a problem.

In prior winters I have mentioned the challenges of hard, icy snow underfoot and the value of using spikes especially for descending and traversing. Snow at all elevations will become increasingly firm and icy following multiple freeze-thaw cycles, and I cannot overemphasize the importance of having both appropriate equipment and the right skill set for the terrain. The latter includes interpreting the snow/ice conditions, understanding your physical and mental abilities, and conservative decision making. These concerns may steadily increase over the next couple of weeks with dramatically rising then falling temperatures, seasonally stronger insolation, and highly variable snowmelt.

Ernie Maxwell Trail [surveyed 26th February] has an average of 70% snow cover remaining, lower at the southern end and increasing to about 90% near Humber Park. Snow is thin and soft but still slippery, spikes are useful.

Devil’s Slide Trail [surveyed 23rd February] has a well-defined track to follow through continuous snow. Snowshoes are currently useful as snow is soft, otherwise spikes are recommended, at least for descending, but are not critical for early morning ascending if the snow is firm.

Wellman Trail [surveyed 23rd February] has only a lightly traveled snowshoe track along its entire length, with only my own tracks (from 20th and 23rd) between Wellman’s Cienega and Wellman Divide. Nevertheless the route is easy to follow. Snowshoes are ideal for the southern section (in the forest and hence still powdery) and for the switchbacks (sun-exposed with soft snow by mid morning).

Almost all of the Peak Trail [surveyed 23rd February] has been very well-traveled, although in places the most heavily traveled track does not accurately follow the trail route (although my snowshoe tracks from 20th remain readily apparent). There is a well-compacted posthole and snowshoe route from Wellman Divide to about 10,000 ft. As is traditional after a reasonable fresh snowfall, the weekend tram traffic has created a myriad mess of tracks above 10,000 ft. Two different well-traveled snowshoe tracks join the Peak Trail here from Tamarack (roughly following the “Sid Davis” route), and two more join just below Miller Peak (near 10,400 ft). Multiple well-traveled posthole, ski, and snowshoe tracks include one that largely follows the uppermost traverse of the Peak Trail to Summit Junction (meeting Deer Springs Trail).

A well-traveled and well-defined compacted snowshoe track broadly follows the East Ridge Trail route from near the Miller switchback (10,400 ft) to San Jacinto Peak, and is an excellent alternative to the upper Peak Trail.

The Round Valley Trail [surveyed 23rd February] has a well-traveled snowshoe and posthole track through continuous moderate depth snow from Long Valley to Wellman Divide. Multiple alternate tracks turn off to head more directly up to the Peak Trail, as described above.

Deer Springs Trail [surveyed 23rd February] has a heavily-traveled posthole track to the Suicide Rock Trail junction. Thereafter the route has been lightly traveled, with the only track that exactly follows the trail route my descending snowshoe tracks from 23rd (between upper Little Round Valley [LRV] and the Suicide junction). Snow below 8600 ft (just south of the Marion junction) is very soft by about late morning and snowshoes make for a much easier hike than miles of deep postholing. From the junction with Marion Mountain Trail, a better-traveled snowshoe track exists briefly, with much of the weekend traffic turning back by the Fuller Ridge junction. A couple of snowshoe tracks and one posthole track continue toward Little Round Valley, with the lone posthole track ending about 0.5 mile below LRV. Much of the section between 8800-9500 ft is sheltered and snowshoes are invaluable through the light powder. Two snowshoe tracks pass through LRV, with only my descending track from 23rd accurately following the trail. From LRV to San Jacinto Peak there is only one known continuous track, my snowshoe tracks which descend very directly from the uppermost switchback (example photo below). I did find one other up-and-down snowshoe track just above LRV, but it was unclear whether this makes it to the Peak.

Marion Mountain Trail [surveyed 23rd February] has a moderately well-traveled snowshoe track along its entire length that largely follows the true trail route. When firm spikes are recommended, at least for descending, but later in the day and on warmer days, snowshoes are invaluable.

As of 23rd February there were no tracks through continuous snow on Seven Pines Trail, Fuller Ridge Trail (PCT Miles 185.5-190.5), or Strawberry Trail (PCT Miles 181-183).

Early on the morning of Saturday 21st we broke trail through light to moderate depth snow on South Ridge Road and South Ridge Trail to Tahquitz Peak (photos below). At that time these routes were untraveled, but by the time we descended, other hikers were postholing through rapidly softening snow at least part way to the peak. One week later on Saturday 28th South Ridge Trail was largely clear of snow to Old Lookout Flat (7600 ft), with only about 10% coverage of small, soft snow patches below that elevation. Snow remains virtually continuous from there to Tahquitz Peak, but is of course much thinner and softer, with largely continuous postholing. Four new blowdowns that came down on this trail in the mid February storms have already been removed by the Trail Report.

The 0.4 mile section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak currently has no track to follow through steeply angled icy snow. These icy slopes on the north side of Tahquitz Peak are notoriously treacherous. Currently crampons with an ice axe, and the requisite skills to use this equipment in high angle terrain, are critical.

Spitler Peak Trail [surveyed 27th February] is functionally clear of snow, with a few limited patches of soft, thin snow remaining in the upper third of the trail. The Trail Report cleared another nine trees from the lower four miles of the trail; we have now removed 183 trees from this trail in recent years. Unfortunately the trail suffered major blowdowns in the most recent storm sequence and four large burned cedars are seriously obstructing the trail between 3.2-4.0 miles up from the trailhead. Several additional small trees remain uncut closer to the PCT.

SNOW DEPTHS

Snow depths measured on 16th-20th February 2026 (unless indicated otherwise) are as follows. Current total depth is the principal number given, followed (in parentheses) by details of the fresh snowfall where known. Altitudes and PCT mileages are approximate.

San Jacinto Peak (10810 ft): 26 inches, drifted 3-4 feet deep in places, notably on east and north sides, especially East Ridge (14 inches on 16th, 7 inches on 17th, 5 inches on 18th)[patchy icy snow persisting from storms in late November was a negligible 0-3 inches deep]

Little Round Valley (9750 ft): 23 inches, drifted to 30-35 inches in places (measured 23rd February)

Wellman Divide (9700 ft): 20 inches (9 inches on 16th, 8 inches on 17th, 3 inches on 19th)

Annie’s Junction/PCT Mile 181 (9020 ft): 27 inches (13 inches on 16th, 10 inches on 17th, 4 inches on 19th)

Tahquitz Peak (8836 ft): 23 inches (measured on 21st, heavily drifted in this exposed location)

Long Valley (8500 ft): 14 inches (8 inches on 16th, 4 inches on 17th, 2 inches on 19th)

Strawberry Junction/PCT Mile 183 (8100 ft): 15 inches (measured 23rd February)

Saddle Junction/PCT Mile 179 (8070 ft): 22 inches (11 inches on 16th, 8 inches on 17th, 3 inches on 19th)

Suicide Rock/Deer Springs trails junction (7000 ft): 8 inches (measured 23rd February)

South Ridge Trail trailhead at top of South Ridge Road (6500 ft): 16 inches (measured 21st)

Devil’s Slide Trail trailhead at Humber Park (6500 ft): 17 inches (9 inches on 16th, 6 inches on 17th, 2 inches on 19th)

Idyllwild (at 5550 ft): 12.5 inches snow (6 inches on 16th, 3.5 inches on 17th, 3 inches on 19th) with 0.57 inches rain on Monday 16th preceding the snow.

Mountain Center (4500 ft): 2 inches (mainly on 16th and 19th, already largely melted).

Quinn Flat, Garner Valley (4450 ft): 1.25 inch (0.25 on 17th, melted, plus one inch on 19th).

The San Jacinto Trail Report celebrates ten years of operation in 2026. It is read by over 30,000 people each year, and will pass one million views in 2026. The Report has helped thousands of hikers, and saved multiple lives, both directly and indirectly. Since the Report became established online, snow/ice rescues in the San Jacinto Mountains have dropped 82%, also saving Riverside County tens, if not hundreds, of thousands of dollars. While all time is volunteered, the Report uses small private donations to help cover operating costs. Donations keep the Report available to all, free from advertising or paywalls, and independent from agencies. If you have found this Report useful, please consider using this link to the Donate page. Thank you for your support.

Back-to-back-to-back storm systems – expected to be the coldest and most vigorous of the season to date – are forecast for the region between Monday 16th and Thursday 19th February 2026. The three systems will impact the San Jacinto mountains on the afternoon and night of 16th, the night of 17th, and throughout the day on 19th, with significant clearing between each, at least in the high country.

Please check this page for periodic updates – the most recent is at the top – throughout the multiday storm sequence. The next comprehensive Report update, summarizing conditions after the storms, is tentatively scheduled for the afternoon of Friday 20th.

UPDATE Thurday 19th February 2026 at 1830

Steady snowfall since late morning at San Jacinto Peak has totaled four inches, with possibly a little more to come this evening. All the snow has been extremely fine rounded grains, which makes for lovely powder, but accumulates very slowly.

In Idyllwild about 1.5 inches of snow has accumulated (at 5550 ft) but even at that elevation it has been admixed with sleet.

UPDATE Thurday 19th February 2026 at 1230

Snowshoeing conditions were exceptionally good on my ascent to San Jacinto Peak this morning, with very firm powder throughout. Temperatures are frigid however, below freezing everywhere above 4000 ft, with severe windchills in the high country.

Total snow accumulation at San Jacinto Peak is currently 21 inches, but with dramatic drifting everywhere above 9000 ft.

It started snowing both in Idyllwild and the high country at about 1115. Snow falling above 10,000 ft is extremely fine rounded grains, currently accumulating at just 0.25 inch/hour.

UPDATE Wednesday 18th February 2026 at 1200

The second storm of the sequence produced only seven inches of fresh snow at San Jacinto Peak overnight, for a total accumulation of 21 inches. Drifting has been severe, with strong winds at upper and mid elevations all night.

Fresh snow in Idyllwild (at 5550 ft) was an unexpectedly low three inches. Snow quality below 6000 ft is atrocious, with a very high water content, bordering on glorified slush. The overnight snow was preceded by 0.13 inch of rain late yesterday afternoon.

Snow dusted as low as 4400 ft in Garner Valley. Cloud became patchy by mid morning, with no further precipitation expected today.

The USFS gate at Humber Park closed on 18th February. While theoretically nine legal parking spaces remain immediately below the gate, an unconventional ploughing approach this time has left space for only 2-3 vehicles to park safely. Parking on Forest Drive, just below the Fern Valley Water District facility, is strongly recommended.

UPDATE Tuesday 17th February 2026 at 1430

Snow depths measured on my hike this morning were: 9 inches at Devil’s Slide trailhead at Humber Park; 11 inches at Saddle Junction (8100 ft); 13 inches at Annie’s Junction (9020 ft); 9 inches at Wellman Divide (9700 ft); 14 inches at San Jacinto Peak.

The snow quality deteriorated as I descended, with delightful, fine, dry powder in the high country down to about 8500 ft, becoming markedly wetter and heavier below that elevation, especially on Devil’s Slide Trail.

Although the high country was largely above the cloud, it was snowing intermittently below 9000 ft on the west side of the mountains during my early afternoon descent, especially in Strawberry Valley (where Idyllwild is located), which traditionally gets socked in during storms that originate from the south-west.

Despite the air temperature only 1-2 degrees above freezing in Idyllwild this afternoon, melting has been rapid with nearly half of the overnight snow already melted.

UPDATE Tuesday 17th February 2026 at 0615

Total snow depth at San Jacinto Peak this morning is 14 inches, following a further eight inches overnight.

I recorded a short video report from the Peak at about 0830 (linked here). At this time, snow conditions are excellent for snowshoeing above 8000 ft, as low as 7000 ft in places.

Idyllwild (at 5550 ft) has had a storm total of six inches of snow. Snow dusted as low as 4500 ft elevation in places (but this has since melted rapidly).

The San Jacinto Trail Report celebrates ten years of operation this year. Since the Report became established online snow/ice rescues in the San Jacinto Mountains have declined 82%, the Report has been used by tens of thousands of hikers, and multiple lives have been saved, both directly and indirectly. While all time and labor is volunteered, the Report uses small donations to help cover modest operating costs. This keeps the Report available to all, free from paywalls or advertising, and independent from agencies. If you have found this Report useful, please consider using this Donate page link. Thank you very much for your support.

UPDATE Monday 16th February 2026 at 1950

Snow accumulated to 2.25 inches in Idyllwild (at 5550 ft) this evening before stopping at about 1900. It has also stopped in Long Valley (8500 ft) where about four inches fell this afternoon.

Very light snow of fine rounded grains continues at San Jacinto Peak, where the total depth is now about six inches (but heavily drifted). A final band of intense snow – to complete the first storm of three – is forecast for the early hours of tomorrow morning.

UPDATE Monday 16th February 2026 at 1630

Rain in Idyllwild this afternoon totaled 0.57 inch before turning to steady snowfall at about 1600.

In the high country snow has been steady all afternoon, but being very fine grains it is accumulating slowly, with three inches at San Jacinto Peak in the past five hours, and about two inches in Long Valley (8500 ft).

UPDATE Monday 16th February 2026 at 1430

As forecast, snow started falling right as I summited San Jacinto Peak at 1130. The fine grain snow, drifting in gusty winds, is accumulating at about 0.5 inch/hour. Winds have so far not been close to the gale force that was forecasted.

The initial wave of the first storm is relatively mild, and light rain started in Idyllwild at 1230, with 0.25 inch falling by 1430. The expectation is that it will start snowing at mid elevations overnight.

To date this has been the second poorest winter on record for snow in the high country (following the desperately dry 2024/25). Snow persisting from storms in November has largely gone from the high country, although what little remains (generally >10,000 ft) is now icy and treacherous in places following months of freeze/thaw cycles. It was unprecedented that the Pacific Crest Trail was clear of snow throughout the San Jacinto mountains at the end of January. The lightest dusting of snow on 5th February – just 0.25 inch above 9900 ft – made conditions even more treacherous at highest elevations, albeit only for a day.

The encouraging news is that high pressure moves away from Southern California this week, and a sequence of storm systems is forecast to impact the San Jacinto mountains. The storms are forecast to be colder than those earlier this winter, with significant snow forecast down to mid elevations, freeze levels at times as low as 5000 ft (meaning snow could dust as low as 4000 ft), and substantial snowfalls possible in the high country.

Snow estimates on 16th-18th February for 5000-6000 ft (e.g., Idyllwild-Pine Cove) range from 4-12 inches, potentially admixed with 1-3 inches of rain, somewhat depending on the freeze level elevation, with high country forecasts ranging widely between 10-50 inches of snow >10,000 ft, with around 20-30 inches currently thought to be most likely. Cold and unsettled conditions may persist until 22nd February.

An initial, very minor, warmer system on Wednesday 11th failed to produce any snow in the high country and only 0.03 inch of rain at mid elevations.

Hikers must be prepared for temperatures below freezing at higher elevations starting Tuesday 10th February, and far below freezing when considering wind chill effects. High country temperatures on 16th-18th February are forecast to be the coldest of the season so far, with periodic blizzard conditions, and potential for dangerous windchills. See the Weather section below for my most recent meteorological observations from San Jacinto Peak.

Obviously, trail conditions are expected to change dramatically over the course of the next week. At this time, spikes are valuable, but not critical, in icy snow areas (generally >9800 ft). From Monday 16th onwards, some combination of snowshoes and crampons/ice axe may well be recommended as low as 8000 ft (potentially much lower), with spikes useful as low as 5000 ft. These recommendations will of course be updated constantly over the next few days and weeks.

Black Mountain Road (4S01) is closed at the gate 1.7 miles up from Highway 243, due to “winter conditions” per US Forest Service. Following superficial grading late in 2025 the road is in better condition than last summer, but remains far rougher than in June 2020, the last time Black Mountain Road was thoroughly graded. South Ridge Road (5S11) reopened to vehicles on 26th January, but is expected to close again around 15th-16th February. Dark Canyon Road remains open at this time, but is also expected to close around 16th. Forecast snowfall will likely result in Humber Park closing starting 16th, but nine legal parking spaces will remain below the gate.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically 2-3 times per week (even more frequently before, during, and after storms), Tahquitz Peak and associated trails at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

High pressure returned to the region in late January, with temperatures again rising to well above seasonal. Unsurprisingly, melting of what little snow remained, largely from November, has been steady.

A rare cloudy day, with moisture emanating from the south, produced the lightest dusting of snow on 5th February, just 0.25 inch of snow above 9900 ft, but no measurable rainfall at mid elevations (see photos above and below).

The “blocking” high pressure ridge is forecast to give way to a track of low pressure storm systems in mid month. A major storm system 16th-18th February may well be the coldest of the season to date. A freeze level as low as 4500 ft is tentatively forecast to produce significant snowfall at the mid-elevations (e.g., Idyllwild-Pine Cove and perhaps even lower). About 6-12 inches of snow are possible in Idyllwild. Snow estimates for the highest elevations have been diverse, but largely fall in the range of 2-4 feet, with the lower end of that range currently forecast as most probable.

At San Jacinto Peak (10,811ft/3295m) on Thursday 12th February 2026 at 0920 the air temperature was 27.6°F (-2°C), with a windchill temperature of 17.2°F (-8°C), 32% relative humidity, and a gentle SW wind sustained at 6 mph gusting to 9.6 mph.

At the Peak on Monday 9th February 2026 at 0910 the air temperature was 50.7°F (10°C), with a windchill temperature of 39.9°F (5°C), 28% relative humidity, and an intermittent NW breeze sustained at 0 mph gusting to 4.5 mph. This air temperature observation shattered the previous record high for the Peak in the month of February (by an almost incomprehensible 9.9°F), the prior record unsurprisingly set just last year.

At the Peak on Friday 6th February 2026 at 0900 the air temperature was 33.4°F (1°C), with a windchill temperature of 19.6°F (-7°C), 63% relative humidity, and a light SE wind sustained at 6 mph gusting to 11.7 mph, with 0.25 inch of fresh snow since the previous day.

At the Peak on Thursday 5th February 2026 at 0920 the air temperature was 32.3°F (0°C), with a windchill temperature of 20.1°F (-7°C), 39% relative humidity, and a steady SSE wind sustained at 10 mph gusting to 13.4 mph, with a few sparse snowflakes in the air.

TRAIL CONDITIONS

All major trails are clear of snow or, at uppermost elevations, have reliable tracks to follow through the very limited remaining icy snow. Most trails currently resemble the spring melt season of April-May, rather than late January/early February. As discussed above, conditions are expected to change dramatically starting 15th February.

Snow cover averages 30% in trails above about 9700 ft (Deer Springs Trail) and 9900 ft (Peak Trail), and is very icy as it is now compacted from hiker traffic and many freeze/thaw cycles.

Spikes remain useful for the next few days at least due to extensive icing above about 9800 ft. Hikers very comfortable on icy snow will find they are generally unnecessary for ascending, but spikes tend to be especially helpful for descending.

The PCT north from Saddle Junction and from Annie’s Junction onward to Strawberry Junction (Miles 179-183) is functionally clear of snow. Spikes not required.

The PCT south from Saddle Junction is functionally clear of snow, with a few very thin icy patches on the north side of Red Tahquitz (Miles 175-177) but spikes are not needed. Further south (Miles 151-175) the PCT is clear of snow.

The 0.4 mile section of South Ridge Trail on the north side of Tahquitz ridge from Chinquapin Flat to Tahquitz Peak is functionally snow-free, which is unprecedented for the end of January.

South Ridge Trail south of Tahquitz Peak is clear of snow.

Snow cover on the Wellman Trail averages less than 5% and is generally very thin.

The Peak Trail is now functionally clear of snow from Wellman Divide to 9900 ft. Icy snow cover in the trail is continuous in the sheltered section from 9900-10,100 ft. Snow cover is now only 10% from there to 10,400 ft (the Miller switchback), but then averages 90% from there to San Jacinto Peak. Many hikers will find spikes useful on this section for descending. At this time most hiker traffic has remained on the route of the upper trail (photo below). There are at least three relatively lightly traveled tracks on the East Ridge Trail route, through 90% snow cover, which rarely follow the actual trail, and for which spikes are very useful (for descending at least). Immediately around San Jacinto Peak (>10,500 ft) snow cover remains 80% and is very icy due following dozens of freeze/thaw cycles; spikes are recommended.

Marion Mountain Trail is now clear of snow. The Trail Report had already cleared the four new treefall hazards downed on this trail so far this winter. A new huge rotten stump came down on the upper trail in the first week of February, but I have cleared an easy work-around for hikers.

Deer Springs Trail is functionally clear of snow to 9000 ft, just above the Fuller Ridge Trail junction. There are a few significant icy snow patches from there to 9700 ft (the lower end of Little Round Valley). From Little Round Valley to near San Jacinto Peak snow cover averages 40%, but in most places on the trail it is more ice than snow. Hikers will find spikes useful on the upper trail, especially for descending some or all of the route from the Peak down to Little Round Valley.

Seven Pines Trail [surveyed 30th January] is clear of snow. The trail is in generally excellent condition (for this true wilderness trail) with most cones and branches now removed. One of two new blowdowns from this winter has been removed, bringing to 101 the number of trees dealt with by the Trail Report on this route in the past decade. An easy work-around has been put in past the huge uprooted tree high up on the trail. Note that Dark Canyon Road, the access to the Seven Pines trailhead, remains open (but is likely to close next week after significant snowfall).

Fuller Ridge Trail (PCT Miles 185.5-190.5) [surveyed 26th January] is functionally clear of snow.

Black Mountain Trail [surveyed 21st January] is clear of snow. The Trail Report has cleared the trail of the two most obstructive blowdowns roughly 1.6 miles up from the highway. Another one in that area, plus one just below Boulder Basin, are both easily hiked over.

Twelve blowdowns were removed from Spitler Peak Trail on 28th January, bringing to 174 the total number of trees the Trail Report has removed from this route in the past seven years. The trail is clear other than one very large burned cedar across the trail immediately after the first creek crossing 3.2 miles up from the trailhead.

The San Jacinto Trail Report celebrates ten years of operation this year. It is now read by over 30,000 people per year, and will pass one million views in 2026. The Report has helped thousands of hikers and saved multiple lives, both directly and indirectly. Since the Report became established online, snow/ice rescues in the San Jacinto Mountains have declined 82% according to Riverside County, saving the county tens, if not hundreds, of thousands of dollars. While all time is volunteered, the Report uses small donations to help cover operating costs, keeping the Report available to all, free from paywalls or advertising, and independent from agencies.

The abysmal snow season continues. Total snowfall to date at San Jacinto Peak (32 inches) is the second lowest in recorded history, with only last winter lower. However, with such warm conditions for much of December and January, the actual snow on the ground around the high peaks this year (0-3 inches) was the lowest on record as of the end of January.

The dusting of snow on Friday 23rd January (described below in Weather) melted within days despite frigid temperatures in the high country. Temperatures climbed again to well above seasonal starting 28th January, with melting expected to remove most of what pitifully little snow remains (almost entirely from late November storms). There is some optimism in the forecasts that the current “blocking” high pressure ridge will give way to a low pressure storm track in mid month, with snow possible most likely starting Saturday 14th February.

It is unprecedented that the Pacific Crest Trail was functionally clear of snow throughout the San Jacinto mountains by the end of January, and hikers remaining on the trail do not require spikes (those taking alternate routes via San Jacinto Peak will find spikes very useful for at least the next week or two, as described under Trail Conditions).

South Ridge Road (5S11) reopened to vehicles on 26th January having been partially blocked by a rockslide about 0.5 mile up following heavy rains at the end of December. The main boulder was moved to a less obstructive position on 23rd (photo below).

Black Mountain Road (4S01) remains closed at the gate 1.7 miles up from Highway 243, due to “winter conditions” per US Forest Service. Following superficial grading late in 2025 the road is in better condition than last summer, but it remains far worse than in June 2020, the last time Black Mountain Road was thoroughly graded.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically 2-3 times per week (even more frequently before, during, and after storms), Tahquitz Peak and associated trails at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

With high pressure returning to the region in late January, temperatures have risen once again to well above seasonal, with the possibility of Santa Ana winds on the last couple of days of the month, and again on 3rd-5th February. The “blocking” high pressure ridge may give way to a track of low pressure storm systems in mid month. The first of these is tentatively forecast for 14th-15th February. Although details remain unclear, the system may be cold (unlike most other storms this season), with snow possible as low as the mid-elevations (e.g., Idyllwild-Pine Cove and perhaps even lower).

A weak “cut-off” low pressure system passed across Southern California on 22nd-24th January, and subsequently contributed moisture to the dramatic weather well to our east, but generated only minimal snow in the San Jacinto mountains. A dusting overnight on 22nd-23rd included 0.5 inch above 9000 ft increasing to one inch at San Jacinto Peak. The air temperature at the Peak was already just above freezing when I summitted early on 23rd, with rapid melting already well underway especially on the sun-exposed slopes. Idyllwild (at 5550 ft) recorded 0.04 inch of rain.

At San Jacinto Peak (10,811ft/3295m) on Thursday 5th February 2026 at 0920 the air temperature was 32.3°F (0°C), with a windchill temperature of 20.1°F (-7°C), 39% relative humidity, and a steady SSE wind sustained at 10 mph gusting to 13.4 mph, with a few very sparse snowflakes in the air.

At the Peak on Sunday 1st February 2026 at 0840 the air temperature was 40.4°F (5°C), with a windchill temperature of 27.3°F (-3°C), 29% relative humidity, and a pleasant SSE wind sustained at 11 mph gusting to 16.7 mph.

At the Peak on Friday 30th January 2026 at 0925 the air temperature was 34.9°F (2°C), with a windchill temperature of 19.8°F (-7°C), 29% relative humidity, and a steady NNE wind sustained at 18 mph gusting to 25.3 mph.

At the Peak on Monday 26th January 2026 at 0840 the air temperature was 21.8°F (-5°C), with a windchill temperature of 2.5°F (-17°C), 16% relative humidity, and a frigid SSE wind sustained at 16 mph gusting to 24.0 mph.

At the Peak on Sunday 25th January 2026 at 0840 the air temperature was 20.6°F (-6°C), with a windchill temperature of 3.9°F (-16°C), 18% relative humidity, and a brisk NNW wind sustained at 10 mph gusting to 16.2 mph.

TRAIL CONDITIONS

All major trails are clear of snow or, at uppermost elevations, have reliable tracks to follow through the limited remaining icy snow. Most trails resemble the spring melt season of April-May, rather than late January/early February.

Snow cover averages >40% in trails above about 9700 ft (Deer Springs Trail) and 9900 ft (Peak Trail), and is very icy as it is now compacted from hiker traffic and many freeze/thaw cycles. Melting continues steadily as temperatures are generally above seasonal until about 10th.

Spikes are increasingly useful for the next few days at least due to extensive icing above about 9800 ft. Hikers very comfortable on icy snow will find they are generally unnecessary for ascending, but spikes tend to be especially helpful for descending. Snow depths are now generally too shallow for crampons, and both depth and conditions are inadequate for snowshoes even at the highest elevations.

Devil’s Slide Trail is clear of snow.

The PCT north from Saddle Junction and from Annie’s Junction onward to Strawberry Junction (Miles 179-183) is functionally clear of snow. Spikes are not required.

The PCT south from Saddle Junction is functionally clear of snow, with a few very thin icy patches on the north side of Red Tahquitz (Miles 175-177) but spikes are not needed. Further south (Miles 151-175) the PCT is clear of snow.

The 0.4 mile section of South Ridge Trail on the north side of Tahquitz ridge from Chinquapin Flat to Tahquitz Peak is functionally snow-free, which is unprecedented for the end of January (photo below).

South Ridge Trail south of Tahquitz Peak is clear of snow.

Snow cover on the Wellman Trail averages less than 5% and is generally very thin, so most of the remainder of this largely sun-exposed trail is expected to clear in the next week or so. In places, notably at Wellman’s Cienega, the trail can be very icy (due to water, not snow) in the morning.

The Peak Trail is now functionally clear of snow from Wellman Divide to 9900 ft. Icy snow cover in the trail is continuous in the sheltered section from 9900-10,100 ft. Snow cover is now only 20% from there to 10,400 ft (the Miller switchback), but then almost continuous from there to San Jacinto Peak. Many hikers will find spikes useful on this section for descending. At this time most hiker traffic has remained on the route of the upper trail (photo below). There are at least two relatively lightly traveled tracks on the East Ridge Trail route, through 90% snow cover, which rarely follow the actual trail, and for which spikes are very useful (for descending at least). Immediately around San Jacinto Peak (>10,500 ft) snow is very icy due following dozens of freeze/thaw cycles, and spikes are invaluable.

Marion Mountain Trail is now clear of snow. The Trail Report has already cleared the four new treefall hazards downed on this trail so far this winter.

Deer Springs Trail is functionally clear of snow to 9000 ft, just above the Fuller Ridge Trail junction. There are a few lengthy icy snow patches from there to 9700 ft (the lower end of Little Round Valley). From Little Round Valley to near San Jacinto Peak snow cover averages 60%, but in most places on the trail it is more ice than snow. Hikers will find spikes useful on the upper trail, especially for descending from the Peak down to Little Round Valley.

Seven Pines Trail [surveyed 30th January] is clear of snow. The trail is in generally excellent condition (for this true wilderness trail) with most cones and branches now removed. One of two new blowdowns from this winter has been removed, bringing to 101 the number of trees dealt with by the Trail Report here in the past decade. An easy work-around has been put in past the huge uprooted tree high up on the trail. Note that Dark Canyon Road, the access to the Seven Pines trailhead, remains open.

Fuller Ridge Trail (PCT Miles 185.5-190.5) [surveyed 26th January] is functionally clear of snow, with tiny patches of thin icy snow persisting in the most sheltered areas, notably around Mile 186 and 186.5-187.

Black Mountain Trail [surveyed 21st January] is clear of snow. The Trail Report has cleared the trail of the two most obstructive blowdowns roughly 1.6 miles up from the highway. Another one in that area, plus one just below Boulder Basin, are both easily hiked over.

Twelve blowdowns were removed from Spitler Peak Trail on 28th January, bringing to 174 the total number of trees the Trail Report has removed from this route in the past seven years. The trail is clear other than one very large burned cedar across the trail immediately after the first creek crossing 3.2 miles up from the trailhead.

UPDATE Friday 23rd January 2026 at 1430:

A dusting of snow overnight produced 0.5 inch above 9000 ft increasing to one inch at San Jacinto Peak. The air temperature at the Peak was just above freezing when I summitted at 0900 in calm conditions, with rapid melting already well underway especially on the sun-exposed slopes (see photo below). Idyllwild (at 5550 ft) recorded 0.04 inch of rain overnight.

The underfoot conditions have not changed significantly, and advice below regarding traction still applies at this time, with spikes advisable above about 9700 ft.

Further very light precipitation is possible at all elevations in the afternoon of Saturday 24th.

———————————

A weak “cut-off” low pressure system moves across Southern California over the next few days. While this will contribute moisture to dramatic weather much further east by the weekend, impacts in the San Jacinto mountains are forecast to be minimal. Light rainfall is possible on 22nd-24th January at mid elevations, at most a fraction of an inch across 22nd-23rd. The freeze level will be high for January, with no snow possible below 7000 ft. In the high country, very light snow is possible, but forecasts increasingly suggesting one inch above 10,000 ft at the most.

With the high country warming consistently above freezing in the past ten days, melting of remnant snow has been rapid, especially with depths so minimal everywhere. Details are given in the Trail Conditions section below, but at this time carrying spikes remains recommended above about 9900 ft, but they can be useful as low as 8800 ft in places.

South Ridge Road (5S11) closed to vehicles on Saturday 3rd January having been partially blocked by a rockslide about 0.5 mile up following heavy rains (photo in an earlier Report linked here). The boulder was moved to a somewhat less obstructive position on 23rd January (photo below) but the road remains closed. Note that the road, plus of course South Ridge Trail, remain open to hikers. Black Mountain Road (4S01) remains closed at the gate 1.7 miles up from Highway 243, due to “winter conditions” per US Forest Service, but following grading is in its best condition since 2020.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically 2-3 times per week (even more frequently before, during, and after storms), Tahquitz Peak and associated trails at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

With high pressure returning to the region in early January, strong Santa Ana winds were a feature of 9th-16th, with no additional rain or snow since 5th January.

The most recent storm of winter 2025/26 produced significant rainfall at mid elevations on 3rd-4th January, plus a minor snowfall overnight on 4th January. It was significantly colder – with thankfully more snow than rain at upper elevations – than most of the rather mild storms so far this winter (as described in more detail in the previous Report linked here).

The morning of Thursday 8th January was remarkable at San Jacinto Peak. Strong winds had been forecast, and I timed my morning hike to experience them. In truly wild conditions, I recorded the highest wind gust reported in winter at the Peak (60.4 mph) and the highest sustained wind speed I have ever recorded there (44 mph). (The all-time record wind gust recorded at the Peak was 77.8 mph on 9th September 2022 during the passage of Tropical Storm Kay.)

Temperatures remained below average until Friday 9th, but have now risen and remain well above seasonal for 13th-21st January as a “blocking” high pressure system moved back in over California, generally redirecting storm systems far north of the state once again.

Brief cooling is forecast around 22nd-24th January as a very weak storm system passes, with a limited chance of light rain at mid elevations as described above, but currently little (if any) snowfall forecast for the high country.

At Tahquitz Peak (8836 ft) at 0800 on Sunday 18th January the air temperature was 54°F, while simultaneously in Idyllwild (at 5550 ft) it was 39.6°F, a noteworthy example of a temperature inversion in Strawberry Valley (and a remarkably warm temperature for Tahquitz Peak in January).

At San Jacinto Peak (10,811ft/3295m) on Monday 19th January 2026 at 0915 the air temperature was 39.6°F (4°C), with a windchill temperature of 33.5°F (1°C), 26% relative humidity, and a very light due North wind sustained at 4 mph gusting to 7.2 mph.

At the Peak on Friday 16th January 2026 at 0940 the air temperature was 36.8°F (3°C), with a windchill temperature of 21.6°F (-6°C), 17% relative humidity, and a stiff NNE wind sustained at 21 mph gusting to 31.7 mph.

At the Peak on Wednesday 14th January 2026 at 0940 the air temperature was 31.0°F (0°C), with a windchill temperature of 9.5°F (-12°C), 45% relative humidity, and a raging NE wind sustained at 37 mph gusting to 45.3 mph.

TRAIL CONDITIONS

All major trails are clear of snow or have reliable tracks to follow through the limited remaining icy snow. Snow on trails is increasingly patchy but icy cover remains >80% in trails above about 9400 ft (west side) and 9900 ft (east side). However it is generally less than an inch deep below about 9700 ft, and will continue to melt steadily until temperatures drop markedly on 22nd.

Although snow is thin, where it persists on high country trails it is now compacted from hiker traffic, and will continue to undergo freeze/thaw cycles, combining to turn thin powder into firm, often icy, snow. This ice can be unexpectedly treacherous in places.

Carrying spikes remains useful everywhere above about 9000 ft, although hikers very comfortable on icy snow may no longer need them. Spikes tend to be especially helpful for descending, even when they are often unnecessary for ascending.

While crampons can be used on compacted trails and off-trail above about 9900 ft (and visible tracks suggest some folks are indeed using them around the highest peaks), snow depths have rapidly become marginal for crampon use. Snow depths and conditions are inadequate for snowshoes even at the highest elevations.

The 0.4 mile section of South Ridge Trail on the north side of Tahquitz ridge from Chinquapin Flat to Tahquitz Peak [surveyed twice per week this month, most recently 18th January] averages only 30% snow cover. It may be unprecedented that this trail is almost snow-free in late January. Fresh snow that fell on 4th-5th January here is extremely thin, and although becoming icy with some compaction (photo below) most hikers will find spikes are no longer required.

Devil’s Slide Trail [surveyed 18th January] is clear of snow. Spikes are not required.

The PCT north from Saddle Junction [surveyed 16th January] and from Annie’s Junction onward to Strawberry Junction (Miles 179-183) is functionally clear of snow. Spikes are not required.

The PCT south from Saddle Junction [surveyed 18th January] has only a handful of icy patches south to Red Tahquitz (Miles 179-175) although I have observed some hikers are choosing to use spikes in a couple of specific locations. Further south (Miles 151-175) the PCT is functionally clear of snow.

Snow cover on the Wellman Trail [surveyed 16th January] averages only 20% and is generally very thin, so most of the remainder of this largely sun-exposed trail is expected to clear in the next few days. In places, notably at Wellman’s Cienega and for 0.1 mile immediately north, the trail can be extremely icy (due to water, not snow) in the morning.

The Peak Trail [surveyed 16th January] has thin, discontinuous, icy snow cover of about 60% from Wellman Divide to 9900 ft. Spikes can be useful on this section, mainly for descending, but are not required. Snow cover in the trail is continuous from 9900 ft to San Jacinto Peak, and snow is very firm with a well-defined track to follow. Many hikers will find spikes useful on this section for descending. At this time almost all hiker traffic has remained on the route of the upper trail (which currently resembles the “monorail” snow tracks of New England). There is only a lightly traveled snow track on the East Ridge Trail route, which rarely follows the actual trail, and for which spikes are certainly useful. Immediately around San Jacinto Peak snow is very icy due to sun exposure and freeze/thaw cycles, and spikes are valuable.

South Ridge Trail [surveyed 18th January] south of Tahquitz Peak is now clear of snow.

Marion Mountain Trail [surveyed 19th January] is now functionally clear of snow. A few tiny icy patches remain in the most sheltered areas in the central portion of the trail, but spikes are no longer required. The Trail Report has already cleared the four new treefall hazards that have fallen on this trail so far this winter.

Deer Springs Trail [surveyed 19th January] is clear of snow to Strawberry Junction, and is now largely clear of icy snow to the Marion Mountain Trail junction (8700 ft), small patches persisting only in the most sheltered forest areas. From 8700-9400 ft, only limited icy patches remain, although many are tricky underfoot and some hikers may find spikes useful. From 9400 ft through Little Round Valley to San Jacinto Peak, snow cover averages 90%, but in many places on the trail it is more ice than snow. Hikers will find spikes useful on the upper trail, especially for descending from the Peak down to around 9400 ft (the crossing of the North Fork of the San Jacinto River).

Seven Pines Trail [surveyed 19th January] is largely clear of snow. There is currently no track to follow through the remaining thin snow patches above 8400 ft, although navigation would be straightforward for those very familiar with this trail.

Fuller Ridge Trail (PCT Miles 185.5-190.5) [surveyed 19th January] is functionally clear of snow, with patches of thin icy snow persisting in the most sheltered areas, notably around Mile 186 and 186.5-187.

Black Mountain Trail [surveyed 21st January] is clear of snow. The Trail Report has cleared the trail of the two most obstructive blowdowns roughly 1.6 miles up from the highway. Another one in that area, plus one just below Boulder Basin, are both easily hiked over.

The San Jacinto Trail Report celebrates ten years of operation this year. It is now read by over 30,000 people per year, and will pass one million views in 2026.

The most recent storm of winter 2025/26 produced significant rainfall at mid elevations on 3rd-4th January, plus a minor snowfall overnight on 4th January. It was significantly colder – with more snow than rain at upper elevations – than most of the storms so far this winter, especially the very mild storm just three days earlier that was described in detail in the previous Report (linked here).

The morning of Thursday 8th January was a remarkable time to be on San Jacinto Peak. Strong winds had been forecast, and I timed my morning hike to experience them. In truly wild conditions, I recorded the highest wind gust reported in winter at the Peak (60.4 mph) and the highest sustained wind speed I have ever recorded there (44 mph). (The all-time record wind gust recorded at the Peak was 77.8 mph on 9th September 2022 during Tropical Storm Kay.) I recorded a short video from the Peak (linked here) although even that doesn’t seem to adequately convey the dramatic wind speeds.

High pressure returns to Southern California by this weekend with temperatures moving far above seasonal again next week, and, predictably, no significant further precipitation in the forecasts before late January.

With the high country remaining below freezing since Monday 5th, melting has been slow above 8000 ft. Melting will be steady this weekend, especially on sun-exposed slopes, before accelerating dramatically everywhere next week, especially given that snow depths everywhere are minimal.

South Ridge Road (5S11) closed to vehicles on Saturday 3rd January having been partially blocked by a rockslide about 0.5 mile up following heavy rains (photo in previous Report linked here). Note that the road (and of course trail of the same name) remain open to hikers.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (even more frequently during winter storm weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Light snow late on 4th January dusted down to 7400 ft on South Ridge Trail and to 7800 ft on Deer Springs Trail. On 5th I measured 1.5 inches at 8500 ft on South Ridge and two inches at Tahquitz Peak, with one inch at Saddle Junction, two at Wellman Divide and three inches at San Jacinto Peak. I recorded a short video report from San Jacinto Peak at about 1100 (linked here).

Prodigious rain continued until near dawn on 5th at mid elevations, with another 1.21 inches in Idyllwild (at 5550 ft) in the 24 hours to 0700 that morning, for a storm total of 1.93, and remarkably 6.9 inches in the 14 days between 23rd December and 5th January.

Temperatures have remained below average this week, but are forecast to start climbing on Friday 9th, and by next week will be well above seasonal for January, as a “blocking” high pressure system moves back in over California, redirecting storm systems well to the north once again.

Strong Santa Ana (north-east) winds are forecast for 9th-10th January. While air temperatures will actually be rising rapidly, windchills may feel severe, especially around peaks and ridges.

At San Jacinto Peak (10,811ft/3295m) on Thursday 8th January 2026 at 0945 the air temperature was 16.9°F (-8°C), with a windchill temperature of -12.3°F (-25°C), 63% relative humidity, and a record-breaking WNW wind sustained at 44 mph gusting to 60.4 mph. The latter was a record wind gust for winter at the Peak (photo below), and the former an all-time record for sustained wind speed that I have recorded at the Peak.

At the Peak on Monday 5th January 2026 at 1100 the air temperature was 19.7°F (-7°C), with a windchill temperature of -1.5°F (-19°C), 59% relative humidity, and a bitter SW wind sustained at 21 mph gusting to 26.4 mph.

TRAIL CONDITIONS

Snow on trails is increasingly patchy above about 8200 ft, but largely continuous above 9000 ft. However it is thin everywhere, generally only 1-2 inches deep below about 9700 ft, and will melt rapidly as temperatures rise over the next few days.

There were fresh tracks to follow on South Ridge, Wellman, Peak, Deer Springs, and Marion Mountain trails, plus the PCT from Miles 177-181, as early as the afternoon of Monday 5th. There is now also a reliable track to follow through very thin snow on the Round Valley Trail from Long Valley to Wellman Divide.

Carrying spikes remains valuable everywhere above about 9000 ft, and some hikers may find them useful in places as low as 8000 ft. Over the course of the next few days high country trails may become somewhat compacted from hiker traffic, and will undergo freeze/thaw cycles, turning the current powder into firmer, icy snow. Conversely, melting will be rapid as temperatures rise over the next few days, reducing the need for traction, especially below 9000 ft and on sun-exposed slopes. Spikes tend to be especially helpful for descending, even when they seem marginally necessary for ascending.

Crampons could be used above about 9700 ft (Wellman Divide on the east side, Little Round Valley on the west side), at least for the next few days while snow depth is adequate, but they are certainly not required (nor preferable to spikes). Snow depths and conditions are inadequate for snowshoes even at the highest elevations.

The 0.4 mile section of South Ridge Trail on the north side of Tahquitz ridge from Chinquapin Flat to Tahquitz Peak [surveyed 10th January] was, remarkably, almost completely clear of icy snow (that remained from November) when checked on the morning of Saturday 3rd, having been drastically melted by mild rainfall in the preceding days. Fresh snow on this trail from 5th is very thin, and although becoming icy with some compaction, most hikers will not require spikes (photo below).

Devil’s Slide Trail is functionally clear of snow to 7800 ft. Between there and Saddle Junction there are some extended patches of very thin snow, which will become more icy this weekend (before melting completely next week). Most hikers will find spikes are not required.

Snow cover on the Wellman Trail is almost continuous but extremely thin, and most of this very sun-exposed trail will clear rapidly in the next few days.

The Peak Trail has thin but continuous snow cover from Wellman Divide to San Jacinto Peak. The least sun-exposed section at 9900-10,100 ft has also drifted the most, and locally depths are 8-10 inches, but snow is very firm with a well-defined track to follow. At this time almost all hiker traffic has remained on the route of the upper trail, and the few tracks on the East Ridge Trail route are not very apparent due to the firmness of the snow.

South Ridge Trail [surveyed 10th January] south of Tahquitz Peak is largely clear of snow to 8500 ft (about 5% snow cover above 7800 ft). Icy snow is almost continuous above 8500 ft (switchback 9) but is thin and will melt rapidly next week. Hikers may find spikes useful, especially for descending the uppermost trail (photo below).

Deer Springs Trail is functionally clear of snow to Strawberry Junction. Snow is very thin and increasingly patchy from there to about 8500 ft (just south of the Marion Mountain Trail junction), but then largely continuous thereafter through to San Jacinto Peak. Snow will become increasingly patchy next week both above and below Little Round Valley, but due to differential drifting and sun exposure, snow will remain several inches deep in most of Little Round Valley for the next week or so. Hikers will find spikes are useful on the upper trail, especially for descending from the Peak to below Little Round Valley.

The San Jacinto Trail Report celebrates ten years of operation this year. It is now read by over 30,000 people per year, and will pass one million views in 2026. The Report has helped thousands of hikers and saved multiple lives, both directly and indirectly. Since the Report became established online, snow/ice rescues in the San Jacinto Mountains have declined 82%, saving Riverside County tens, if not hundreds, of thousands of dollars.

The sixth storm system of winter 2025/26 to impact the San Jacinto mountains was impressive for both its rain generation, and for its remarkably high freeze level. This combination brought heavy rain – which froze above about 9300 ft – all the way to San Jacinto Peak, but (sadly) minimal fresh snow.

Rainfall began around 0700 on 31st December at both mid and upper elevations, continuing with remarkable persistence until the morning of 2nd January (0500 in Idyllwild, 0700 at 9000 ft). Across the roughly 48 hour period, Idyllwild (at 5550 ft) received 2.98 inches of rain, with Wellman’s Cienega (9300 ft) recording a prodigious 5.2 inches.

Snowfall immediately around San Jacinto Peak was a mere two inches, heavily admixed with freezing rain, sleet, and remnant snow from November and December storms, with just one inch at 10,500 ft, and a dusting as low as 9900 ft.

I recorded a rather lengthy video report from San Jacinto Peak in superb conditions at 0830 on Friday 2nd January (linked here, discussion of trail/ice conditions between minutes 4-5). Icy snow is essentially continuous above 9800 ft, and was so hard and icy that conditions are optimal for spikes. This will change rapidly on sun-exposed areas during the day, but the upper elevations will refreeze overnight, getting icy again every morning. Crampons could be used above about 10,000 ft, but are frankly more than is needed at this time. Snow depth and condition are unsuitable for snowshoes.

Contrary to normal winter reporting, snow depths are not given at the foot of this posting. Rain has largely eliminated all snow from trails below 9800 ft (with the notable exception of uppermost Deer Springs Trail and the north side of Tahquitz Peak). Generally, trails below that elevation are largely or completely clear of snow (but may retain some ice). Snow depth above 10,000 ft is currently 2-5 inches, with deeper drifts in places.

High country temperatures are forecast to be generally around seasonal into mid January. Consequently, hikers must be prepared for air temperatures below freezing above 10,000 ft elevation and well below freezing when considering wind chill effects. See the Weather section below for my recent observations from San Jacinto Peak.

The conditions forecast for 3rd-4th January may be similar to those earlier this winter which resulted in multiple significant hypothermia cases in the San Jacinto high country. Hikers – most notably those from the Tramway where such conditions are less anticipated – may be ascending through rain, before encountering snowfall, stronger winds, and frigid windchills at the highest elevations. Being fully prepared for the challenging combination of both winter conditions and wet weather can be critical (at a minimum, having fully wind- and waterproof clothing, plus multiple dry layers, hats, and gloves stored in a truly waterproof pack system, is very strongly advised). A clear recognition of when turning around is the safest option in such conditions is also invaluable.

South Ridge Road (5S11) closed on Saturday 3rd January having been partially blocked by a boulder about 0.5 mile up following recent heavy rains (photo below).

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (but even more frequently during winter storm weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Conditions remain very unsettled, especially at mid elevations, until at least 8th January. Consequently, temperatures remain generally below seasonal, especially at mid elevations, until next weekend.

Light rain is forecast from late on Saturday 3rd to early on Monday 5th January. This system will be colder than most recent ones, with a freeze level near 8000 ft, but with little precipitation forecast (<1 inch rain at mid elevations, 1-2 inches of snow >9000 ft), the impacts will be limited.

The “blocking” high pressure area returns to Southern California later this week, with temperatures moving back above seasonal the following week, with, predictably, no further precipitation in the forecasts thereafter.

At San Jacinto Peak (10,811ft/3295m) on Friday 2nd January 2026 at 0830 the air temperature was 32.4°F (0°C), with a windchill temperature of 18.7°F (-7°C), 34% relative humidity, and a cool due West wind sustained at 11 mph gusting to 17.0 mph.

At the Peak on Wednesday 31st December 2025 at 1100 the air temperature was 33.8°F (1°C),with a windchill temperature of 17.1°F (-8°C), 79% relative humidity, and a sharp SSE wind sustained at 22 mph gusting to 30.8 mph.

At the Peak on Saturday 27th December 2025 at 0730 the air temperature was 15.2°F (-9°C), with a windchill temperature of -7.4°F (-22°C), 100% relative humidity, and a bitter NW wind sustained at 20 mph gusting to 28.2 mph.

TRAIL CONDITIONS

Trails below about 9,800 ft (east side) or 9500 ft (west side) are generally snow-free, but may be icy to lower elevations in early to mid mornings.

Carrying spikes remains advisable everywhere above about 9000 ft. Sections of ice and icy snow that remained from November are now largely obscured under very thin fresh snow cover (>9900 ft), or ice from frozen rain, making them especially treacherous. This is especially true on the Peak Trail above 10,100 ft, and on upper Deer Springs Trail (>9500 ft). Spikes tend to be especially helpful for descending, even when they do not seem necessary for ascending.

Snow depths are generally unsuitable for snowshoeing everywhere due to limited snow depths and compaction/ice.

Remarkably, the section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [updated 3rd January] is largely clear of icy snow, having been melted by rainfall in recent days (photo below). Some hikers may find spikes useful for short sections.

South Ridge Trail [updated 3rd January] south of the peak is clear of snow and ice to Tahquitz Peak.

The Wellman Trail is almost entirely clear of icy snow, other than a handful of patches in the sheltered areas at its southern end.

The Peak Trail has an obvious track through very thin continuous snow cover that accurately follows the trail route to the Summit Junction with Deer Springs Trail, and then onward up to San Jacinto Peak. The snow is extremely icy in mornings and in areas that are not sun-exposed. Spikes recommended.

Upper Deer Springs Trail does not have a track to follow through continuous icy snow above Little Round Valley as of Friday 2nd. The existing tracks have been largely obscured by a mixture of melting, rain, and icy fresh snow. Spikes are strongly recommended for this route.

The San Jacinto Trail Report celebrates ten years of operation this year. It is now read by over 30,000 people per year, and will pass one million views in 2026. The Report has helped thousands of hikers and saved multiple lives, both directly and indirectly. Since the Report became established online, snow/ice rescues in the San Jacinto Mountains have declined 82%, saving Riverside County tens, if not hundreds, of thousands of dollars.

UPDATE Friday 2nd January 2026: it continued to drizzle up to 9000 ft until early this morning. San Jacinto Peak added two inches of snow, but it is embedded in a thick ice layer of freezing rain.

I recorded a video report from the Peak early this morning (linked here) discussing the weather and current conditions.

Spikes are strongly recommended everywhere above about 9000 ft due to heavy icing of all surfaces at this time.

Rainfall was prodigious, with about 5.4 inches at Wellman’s Cienega (9300 ft) in the past 48 hours.

UPDATE Thursday 1st January 2026 at 1745: steady rain overnight and almost all day is finally slowing (almost to a stop at mid elevations). Idyllwild (at 5550 ft) received 1.47 inches in the 24 hours up to 0700 this morning, and another 1.37 inches in the subsequent ten hours, for an impressive storm total of 2.84 inches. Long Valley (8500 ft) recorded 1.63 inches in the 24 hours to midnight last night, with an additional 0.45 inch today. The freeze level remained above 10,000 ft all morning, finally dropping this afternoon closer to 9000 ft (but after the bulk of the precipitation had passed).

UPDATE Wednesday 31st December 2025: I spent most of the day in the high country, as my morning hike turned into substantial involvement in a hiker rescue from San Jacinto Peak. The good news is that all has ended well, but this update was of course delayed. Rain started this morning at 0700, but did not turn heavy at mid elevations until 1500. Above 9000 ft, the rain was heavy for much of the day, with Wellman’s Cienega recording 0.4 inch in just four hours from 0900-1300. Rain in Idyllwild totaled 0.83 inch from 0700-1900 today. The system is very mild, as expected, with rain as high as San Jacinto Peak this morning before turning to intermittent snow and sleet at about 1115, but only above 10,500 ft. Trails that had snow and/or ice remaining from last week (or even November) have fast become an ugly mix of softening snow, watery ice, and, increasingly, slush. Fully waterproof gear, including footwear, is critical for the next 36 hours, in addition to gear for genuine winter conditions. Rain is forecast to persist all night until late tomorrow afternoon, at least to 10,000 ft, with just a few inches of snow expected above that elevation.

UPDATE Tuesday 30th December 2025: an extremely mild winter storm arrives tomorrow morning, bringing steady rain all day on Wednesday and Thursday (totaling about two inches at Idyllwild elevation). The forecast freeze level is remarkably high, not dropping below 10,000 ft, above which 6-8 inches of snow are tentatively forecast, with perhaps a dusting down to 9000 ft. After a hiatus on Friday 2nd January, most of the first half of January remains unsettled, with precipitation possible on many days, and a more typical freeze level – especially in the second week of the month – perhaps eventually bringing snow down to mid elevations.

UPDATE Monday 29th December 2025: in a 180° change in the weather – literally, in terms of the wind direction – strong Santa Ana winds are impacting the mountains today. I recorded a north-easterly wind gust of 43.8 mph at Tahquitz Peak early this morning, but more impressive was the sustained speed at 30 mph, with the wind seemingly strengthening further after we left the peak. Although the direction remains the same, the wind speeds are forecast to drop substantially tomorrow, Tuesday 30th, with rain forecast for the following day.

—————————————-

This update summarizes conditions following the fifth storm system of winter 2025/26 – a major atmospheric river across most of California – that recently impacted the San Jacinto mountains on 23rd-26th December. This update is intentionally brief as (a) very limited snowfall has resulted in generally benign trail conditions, and (b) another very warm storm system starting 31st December expected to bring widespread rain to at least 10,000 ft elevation and lasting into the first few days of January will change conditions significantly once again.

Despite reports of dramatic weather only a short distance to our west, the latest storm greatly underperformed forecasts in the San Jacinto mountains. Across three different days of precipitation, total snow accumulation at San Jacinto Peak was 7.5 inches, with 2.01 inches of rain in Idyllwild (at 5550 ft).

Other than at the end of the storm system on 26th, the bulk of the storm was very mild, and rather than adding snow, rainfall as high as 10,000 ft actually contributed to removing much of the already rather limited snow that remained from November storms. When the freeze level finally dropped, even snowfall on 26th was generally less than 0.5 inch fell below 8500ft, with only an inch to 9900 ft, so impacts on the trails have been very limited.

I recorded a short video discussion from San Jacinto Peak on the morning of Saturday 27th December, giving a feel for the snow conditions underfoot at the highest elevations (linked here). I maintained day-by-day postings on the progress of the multiday storm system available here.

Details are given below under Trail Conditions, but carrying spikes remains advisable everywhere above about 9000 ft, and they can be useful down to 8000 ft in places. Sections of ice and icy snow that remained from November are now largely obscured under thin fresh snow cover, making them especially treacherous. This is especially true on the Peak Trail between 9700-10,100 ft, and on upper Deer Springs Trail (9000-10,500 ft). Spikes tend to be especially helpful for descending, even when they do not seem necessary for ascending.

Snow depths are not currently suitable for snowshoes, except perhaps for off-trail travel around the highest peaks (>10,000 ft), but even then only for the next couple of days as melting is expected to be steady with rising temperatures this week.

Snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow feet deep is often much easier hiking than traversing across just a few inches depth of angled virgin icy snow.

High country temperatures are forecast to remain near or above seasonal for the first ten days of January 2026. Nevertheless, hikers should be prepared for temperatures near or below freezing in the high country (>9800 ft elevation) and at times well below freezing when considering wind chill effects. See the Weather section below for my recent observations from San Jacinto Peak.

The conditions forecast for 31st December-4th January are similar to those on 15th November which resulted in multiple significant hypothermia cases in the San Jacinto high country, and with which I was heavily involved as I alluded in a prior report linked here. Hikers – most notably those from the Tramway where such conditions are less anticipated – may be ascending through rain, before encountering snowfall, stronger winds, and frigid windchills at the highest elevations. Being fully prepared for the challenging combination of both winter conditions and wet weather will be critical (at a minimum, having fully wind- and waterproof clothing, plus multiple dry layers, hats, and gloves stored in a truly waterproof pack system, is very strongly advised). A clear recognition of when turning around is the safest option in such conditions is also invaluable.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (but almost daily during winter storm weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures rise steadily in the last few days of December, with widespread melting of the very thin snow expected. They will remain somewhat above seasonal in the first week of January, especially at upper elevations, even as a new storm system arrives.

The first five days of January 2026 are forecast to be very unsettled, especially at mid elevations. About two inches of rain are expected at Idyllwild elevation (5000-6000 ft) between the afternoon of Wednesday 31st December and Monday 5th January, heaviest on 31st December and 1st January. The system is expected to be even warmer than that of 23rd-24th December, with freeze levels consistently near or even above 10,000 ft. Snowfall around the highest peaks is tentatively forecast to be several inches spread across the five days, mostly falling on 31st and 1st, with little more than a dusting expected down to 8000 ft, and only roughly 1-3 inches in between, following significant rainfall to 10,500 ft or higher.

At San Jacinto Peak (10,811ft/3295m) on Saturday 27th December 2025 at 0730 the air temperature was 15.2°F (-9°C), with a windchill temperature of -7.4°F (-22°C), 100% relative humidity, and a bitter NW wind sustained at 20 mph gusting to 28.2 mph.

At the Peak on Friday 26th November 2025 at 1330 the air temperature was 28.4°F (-2°C), with a windchill temperature of 13.4°F (-10°C), 98% relative humidity, and a surprisingly gentle SW wind sustained at 5 mph gusting to 6.5 mph.

At the Peak on Thursday 25th December 2025 at 0645 the air temperature was 20.6°F (-6°C), with a windchill temperature of -0.2°F (-18°C), 98% relative humidity, and a sharp due West wind sustained at 15 mph gusting to 27.0 mph.

At the Peak on Wednesday 24th November 2025 at 1045 the air temperature was 32.3°F (0°C), with a windchill temperature of 15.6°F (-9°C), 96% relative humidity, and a harsh SSW wind sustained at 20 mph gusting to 28.9 mph.

TRAIL CONDITIONS

Trails below about 9,900 ft (east side) or 9000 ft (west side) have such a thin covering of snow that they are functionally snow-free, or will largely clear of snow within the next day or two. With sunny days forecast on 28th-31st December in the high country, melting will be rapid, especially on sun-exposed slopes.

Spikes can be useful in places above about 8000 ft, but especially above 9000 ft, depending upon personal preference and comfort level hiking on icy snow. Snow on established trails from storms in November has become densely compacted by hiker traffic, has undergone many freeze-thaw cycles, and has recently been rained upon. Spikes are especially useful for descending heavily traveled high elevation trails (e.g., Peak and upper Deer Springs trails), and also the north side of Tahquitz Peak, which remained largely unmelted from November storms.

Snow depths are generally unsuitable for snowshoeing everywhere due to limited snow depths and compaction/ice.

Devil’s Slide Trail is clear of snow, but is very icy in places close to Saddle Junction in the mornings.

The section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [updated 29th December] currently has a well-traveled, uneven track to follow through increasingly patchy angled icy snow. A very thin covering of fresh snow partially obscures the persistent compacted icy snow remaining from November. These icy slopes on the north side of Tahquitz Peak are notoriously treacherous. Currently spikes are recommended; they are not essential for hikers most experienced with icy snow travel, but conversely this route will not feel safe for some hikers.

South Ridge Trail [updated 29th December] is functionally clear of snow, but has a few small but tricky ice patches above 8500 ft. There is a patchy dusting of 0.25 inch of snow admixed with ice around Tahquitz Peak. Most hikers may find spikes useful

As of Saturday 27th, there was a lightly-traveled track to follow through very shallow and rapidly melting snow on the Strawberry Trail (PCT Miles 180.8-183).

There are well-traveled and compacted tracks on Round Valley Trail through Long and Round valleys to Wellman Divide.

The PCT north from Saddle Junction, continuing onto the Wellman Trail, has a well-traveled track through very light snow cover to Wellman Divide [updated Saturday 27th]. Melting has been rapid on the most sun-exposed section immediately north of Saddle Junction (“Angel’s Glide”) with some lengthy snow-free sections already appearing.

The Peak Trail has a well-traveled track through generally thin continuous snow cover that accurately follows the trail route to the Summit Junction with Deer Springs Trail, and then onward up to San Jacinto Peak.

Upper Deer Springs Trail does not have a track to follow through continuous snow above Little Round Valley as of Saturday 27th. The existing tracks will have been completely obscured by fresh snow, which although shallow, was heavily drifted by strong accompanying winds. Spikes are strongly recommended for this route.

Fuller Ridge Trail [updated Saturday 27th] has a lightly traveled but accurate track to follow through very thin snow cover along its entire length (PCT Miles 185.5-190.5).

SNOW DEPTHS

Snow depths measured on 27th December 2025 are as follows. Current total depth is the first number given, followed (in parentheses) by details of the snowfall in the storm of 23rd-26th December. Altitudes and PCT mileages are approximate.

San Jacinto Peak (10811 ft): 10 inches, drifted deeper in places, notably on East Ridge (0.5 inch added 23rd, 3.5 inches on 24th, 3.5 inches on 26th December)

Wellman Divide (9700 ft): 1 inch (1 inch on 26th December)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 1 inch (1 inches on 26th December)

Long Valley (8500 ft): 1 inch (on 26th December)

Saddle Junction/approx. PCT Mile 179 (8070 ft): <0.25 inch (on 26th December)

Devil’s Slide Trail at Humber Park (6500 ft): 0 inch

Idyllwild (at 5550 ft): 0 inch snow, 1.99 inches rain 23rd-26th December.

The fifth storm system of winter 2025/26 is forecast to impact the San Jacinto mountains between Tuesday 23rd and Friday 26th December 2025.

Please check this page for periodic updates – the most recent is at the top – throughout the multiday storm sequence. The next comprehensive Report update, summarizing conditions after the storm, is tentatively scheduled for Saturday 27th.

UPDATE Saturday 27th December at 0700

Overnight snowfall at San Jacinto Peak totaled 3.5 inches, for a rather paltry storm total of 7.5 inches.

I recorded a short video discussion from the Peak at 0730 this morning, giving a feel for the snow conditions underfoot (linked here).

Snow dusted down to 7800 ft, with one inch at 8500 ft (e.g., Long Valley).

Rainfall in Idyllwild at 0700 totaled 0.82 inch in the previous 24 hours.

Hikers this weekend will find spikes invaluable above 9000 ft, as there is extensive ice and icy snow on the main trails now obscured under a thin cover of fresh powder. Snow depths are insufficient for snowshoes, other than perhaps for off-trail travel only around the highest peaks, snd even then only for the next day or two as melting will be steady with warming temperatures.

UPDATE Friday 26th December at 2010

Fine granular snow has so far accumulated to two inches average depth in the past six hours at San Jacinto Peak, although the snow has been heaviest in the past hour.

A light dusting (<0.25 inch) in Long Valley at 8500 ft shortly before dusk melted, it then briefly rained at that elevation before recently turning to snow, with currently 0.5 inch accumulation.

Rainfall this afternoon in Idyllwild totaled 0.47 inch by 1900 (at 5550 ft), where it continues to rain gently.

UPDATE Friday 26th December at 1430

It started raining in Idyllwild at 1350 this afternoon, and about 15 minutes later started snowing lightly and intermittently at San Jacinto Peak. Forecasts have reduced expected precipitation amounts for this final phase of the storm system, with 3-4 inches of snow predicted for the high peaks, and under 0.5 inch rain for Idyllwild. Very light snow is expected as low as 6000 ft.

The Peak Trail is very icy starting immediately above Wellman Divide (9700 ft) and spikes are strongly recommended. The same is almost certainly true on upper Deer Springs Trail (there probably as low as 9000 ft).

UPDATE Thursday 25th December at 1200

There was no further precipitation overnight. I recorded a short video report from San Jacinto Peak this morning just after sunrise (linked here). With clearing skies, a sharp drop in temperatures, and such wet snow yesterday, the snow above 10,000 ft has frozen solid, making for very easy hiking (with spikes and/or appropriate boots).

The next low pressure system arrives tomorrow morning, Friday 26th, and a colder air mass should result in the snow level dropping to 6000 ft, possibly even lower. Snow estimates are about six inches above 10,000 ft and 2-4 inches at 8000 ft (e.g., Saddle and Strawberry junctions). Rainfall of 0.5-0.8 inch is forecast for the mid elevations.

UPDATE Wednesday 24th December at 1915

It stopped snowing at San Jacinto Peak at about 1800, where unfortunately only 3.5 inches accumulated today.

The snow level today was astonishingly high, having dusted down to 9000 ft, but with no more than a barely measurable 0.25 inch at Wellman Divide. On his descent to the tram, Kyle Eubanks described Round and Long valleys as having “many rivers and waterfalls”, such was the volume of rainfall (plus snowmelt).

Idyllwild (at 5550 ft) recorded 0.76 inch of rain today, for a storm total of 1.17 inches, less than half the forecast expectations.

UPDATE Wednesday 24th December at 1630

Snowfall has been largely continuous at San Jacinto Peak for the past four hours, but often light, so far accumulating to 2.5 inches. Winds have been sustained at 25-30 mph, with gusts close to 40 mph, but it feels like the strongest winds and heaviest precipitation have slipped past to the west of the San Jacinto mountains.

Rainfall in Idyllwild since 0700 today has totaled 0.45 inch, for a storm total of 0.86 inch so far, roughly half of forecast.

That said, rain intensity is clearly localized, as Long Valley (8500 ft) is reporting 1.4 inches since midnight. I saw Kyle Eubanks at the Peak this afternoon and he commented that trails in Long and Round valleys were “like rivers”, so the relatively low rainfall for Idyllwild is evidently not representative of the whole mountain.

UPDATE Wednesday 24th December at 1200

Precipitation largely stopped at mid and upper elevations between 0700-1000, with light rain starting again above 10,000 ft at about 0950, finally turning to snow at 1150 around San Jacinto Peak. Winds are getting potent in the high country, sustained from SSW at 20 mph, gusting to 29 mph, but forecast to continue strengthening.

UPDATE Wednesday 24th December at 0620

At least in the San Jacinto mountains the initial front of the atmospheric river system is so mild (relatively speaking) that it is currently raining all the way to San Jacinto Peak.

Patchy, and at times intense, rain started in Idyllwild at 0200, with rain accumulation overnight 0.26 inch in Idyllwild (at 5550 ft), for a current storm total of 0.41 inch, with 0.22 reported in Long Valley (8500 ft).

UPDATE Tuesday 23rd December at 1700

One “arm” of the dramatic low pressure system forming off the California coast passed over the San Jacinto mountains around 1130 this morning, bringing light precipitation throughout. The temperature plunged more than 10°F in less than half-an-hour in the high country, and it briefly snowed above 8000 ft (with 0.5 inch briefly accumulating above 10,000 ft, and barely a dusting in Long Valley), and about 0.02 inch of drizzle in Idyllwild. The temperature rose again subsequently, largely melting the minimal fresh snow. It remained misty and drizzly throughout the early afternoon, totaling 0.15 inch in Idyllwild, before beautifully clearing out at dusk.

The major blocking high pressure area over the south-west of the country continued to generate very warm and dry conditions for our region for most of the first three weeks of December. A significant atmospheric river system is forecast to impact Southern California on 23rd-26th December. While precipitation volumes and timing remain somewhat uncertain for the San Jacinto mountains, the bulk of the system will be relatively mild, with a high freeze level, and snowfall largely above about 9000 ft, before the freeze level drops, with snow possibly as low as 6500 ft, by late on 26th. Considerable rainfall (2.5-3.5 inches across four days) is expected throughout mid elevations. Unsettled conditions, with possibilities for further light precipitation (snow in the high country, rain at mid elevations) may persist for the last three days of the year and the first three days of January.

Since the minor snow storms that impacted the region for nine days in mid November – discussed in detail in a prior Report linked here – temperatures generally well above seasonal have led to very rapid snow melt for the time of year (photos below).

The air temperature of 52.2°F (11°C) that I recorded at San Jacinto Peak on Thursday 11th December 2025 shattered (by 3°F) the previous high temperature knowingly recorded at the Peak in the month of December.

Once temperatures drop markedly from 23rd December onwards, hikers must be prepared for temperatures below freezing at high elevations, and potentially far below freezing when considering wind chill effects, with strong winds (>30 mph) forecast on many days. See the Weather section below for my recent observations from San Jacinto Peak.

The conditions forecast for 24th-25th December are similar to those on 15th November which resulted in multiple significant hypothermia cases in the San Jacinto high country (the overlap with a holiday period adding a further complication) to which I briefly alluded in a prior report linked here. Hikers – most notably those from the Tramway where such conditions are rarely anticipated – may be ascending through rain, before encountering snow, strong winds, and frigid windchills at the highest elevations. Being fully prepared for the challenging combination of both genuine winter conditions and very wet weather will be critical (at a minimum, having fully wind- and waterproof clothing, plus multiple dry layers, hats, and gloves stored in a truly waterproof pack system, is very strongly advised). A clear recognition of when turning around is the safest option in such conditions is also invaluable.

Details are given below under Trail Conditions, but most hikers will find that carrying spikes remains advisable in areas above about 9000 ft, although experienced hikers will find they are generally no longer needed on established trails even well above that elevation. Spikes tend to be especially helpful for descending, even when they seem to be of limited use for ascending.

Current snow depths measured at various locations on the trail system are given near the foot of this posting. Note that these are expected to change starting Wednesday 24th. Also note that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow feet deep is often much easier hiking than traversing across just a few inches depth of, for example, angled virgin icy snow. Conversely, just a one inch covering of icy snow at mid-elevations (where there have been many freeze-thaw cycles) can be among the most treacherous surfaces to hike.

Black Mountain Road (4S01) closed to vehicle traffic in mid November at the gate 1.7 miles up from Highway 243. Despite being clear of snow for most of December it is now expected to remain closed for the winter season, per Forest Service.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice every week (and even more frequently during stormy weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures have generally been well above seasonal since the last week of November (with the brief exception of 1st-4th December). They are forecast to remain far above seasonal until 22nd December, after which the current “blocking” high pressure system is forecast to move east, allowing a storm system flow to return (perhaps only briefly) to Southern California.

Significant rainfall is expected at mid elevations, with about three inches of rain forecast between 23rd and 26th December at 5000-6000 ft. Rainfall will be heaviest and probably continuous on Wednesday 24th, but lighter and more intermittent on 25th-26th.

Snowfall predictions for the high country have varied significantly, but most recent forecast models suggest 12-20 inches of snow are possible around the highest peaks of the San Jacinto mountains, largely on Wednesday 24th but continuing into the 25th. Regardless of precise snow volumes, the system is expected to be relatively warm, at least initially, with freeze levels largely remaining above 8000 ft, and hence little (or possibly even no) snowfall expected at mid elevations. It is most likely that any snowfall in the mid elevations will accumulate as the coldest part of the storm system moves through late on Friday 26th, when 1-2 inches are possible at the higher elevations of Pine Cove and Fern Valley.

Further waves of unsettled weather are tentatively forecast almost daily between 29th December and 3rd January, with light rainfall (mid elevations) and very light snowfall (highest elevations) possible on some or even all of those days. Currently the timing and volume of precipitation on those days is uncertain, but will become clearer over the course of the next week.

The second, third, and fourth storm systems of winter 2025/26 all impacted the San Jacinto mountains in quick succession, on 14th-16th, 17th-18th, and 20th-22nd November, respectively. All three storms were relatively mild, with high freeze levels and very limited snow below 7000 ft. The storm sequence and precipitation outcomes were described in detail in an earlier Report (linked here).

At San Jacinto Peak (10,811ft/3295m) on Monday 22nd December 2025 at 0845 the air temperature was 39.9°F (4°C), with a windchill temperature of 27.5°F (-2°C), 26% relative humidity, and a stiffening SW wind sustained at 12 mph gusting to 20.3 mph.

At the Peak on Thursday 18th December 2025 at 0840 the air temperature was 44.3°F (7°C), with a windchill temperature of 34.5°F (1°C), 44% relative humidity, and a fresh NW wind sustained at 10 mph gusting to 15.6 mph.

At the Peak on Monday 15th December 2025 at 0830 the air temperature was 40.4°F (5°C), with a windchill temperature of 34.5°F (1°C), 22% relative humidity, and a very light due North wind sustained at 2 mph gusting to 5.5 mph.

At the Peak on Thursday 11th December 2025 at 0830 the air temperature was 52.2°F (11°C), with a “windchill” temperature of 48.4°F (9°C), 15% relative humidity, and a barely discernable SE wind sustained at 2 mph gusting to 3.5 mph. This is the first time I have ever recorded an air temperature exceeding 50°F in December at the Peak, and this is undoubtedly a record high for the month at that location.

TRAIL CONDITIONS

Trails above about 9500 ft remain largely snow-covered (details below), especially on the less-exposed western slope trails. With above seasonal temperatures almost continuously since 24th November, melting has been unusually rapid for the time of year, especially on sun-exposed slopes. This melting will continue with warm temperatures forecast to persist until 22nd December.

Spikes can be useful above about 9000 ft, locally as low as 8500 ft, as established trails have become consolidated by hiker traffic and undergone freeze-thaw cycles. They are especially useful for descending parts of heavily traveled tracks where the snow persists (most notably uppermost Deer Springs Trail). Snow depth and condition is no longer suitable for snowshoes, even for off-trail travel at the highest elevations.

Devil’s Slide Trail [updated 22nd December] is now clear of icy snow. A few tiny, persistent, icy snow patches remain above 7700 ft, but most are so dirt-covered at this time that underfoot traction is rarely a concern. Spikes are no longer required.

There is a well-traveled, compacted track on the PCT south from Saddle Junction to Chinquapin Flat/PCT Mile 178 [updated 18th December]. Snow cover has dropped markedly this week, to about 40%.

The section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [updated 20th December] has a very well-traveled track to follow through increasingly patchy angled icy snow. These icy slopes on the north side of Tahquitz Peak are notoriously treacherous, and see so little direct sunlight in December and January that conditions change slowly at this time of year. That said, some cleared patches have appeared this week, especially at the Chinquapin Flat (northern) end. Spikes are recommended for most hikers, but even then parts of the route may not be comfortable for all (photo above).

South Ridge Trail south of Tahquitz Peak [updated 20th December] is now clear of snow to Tahquitz Peak, with a few tiny icy patches remaining above 8500 ft (switchback 9).

The Strawberry Trail (PCT Miles 180.8-183) is functionally clear of snow, other than patches that persist for 0.1 mile at its eastern end, and in a handful of forested sections nearer Strawberry Junction.

Willow Creek Trail [updated 18th December] averages less than 10% thin snow cover to Hidden Divide.

There are well-traveled and compacted tracks on Round Valley Trail through Long and Round valleys to Wellman Divide, and on the “Sid Davis” route, the latter emerging at the Peak Trail near 10,000 ft [updated 15th December]. Both routes are starting to have extensive bare patches appear in their most exposed sections.

The PCT north from Saddle Junction [updated 22nd December] is now clear of snow to 9000 ft elevation, with just a few small icy snow patches persisting on this very sun-exposed south-facing slope. From 9000 ft, where the trail enters forest, to Annie’s Junction, has cleared dramatically in the past few days, and now averages only 10% snow cover. Most hikers will find spikes are not required.

The Wellman Trail [updated 22nd December] averages less than 10% snow cover, concentrated in the forested section at its southern end (closest to Annie’s Junction). Spikes are not required.

The Peak Trail [updated 22nd December] has a rapidly diminishing 30% cover of softening and generally thin snow, largely confined to the sheltered section around 10,000 ft, and then above 10,400 ft. There is a split in hiker traffic – as is traditional in winter – near Miller Peak at 10,400 ft. The East Ridge route is a somewhat meandering (but well-compacted) route through 90% continuous snow cover to San Jacinto Peak. The Peak Trail itself above 10,400 ft now has a heavily-traveled track to follow through 80% snow cover. Trails just below San Jacinto Peak proper have largely consolidated into 3-4 alternate routes, all of which ultimately reach the peak. Spikes are no longer essential on this trail for those with extensive experience of snow hiking. Snow cover on the exposed south- and east-facing slopes around San Jacinto Peak is now only 30%, and averages just 1-2 inches in most places, with drifts to 10 inches.

Deer Springs Trail [updated 15th December] is clear of snow to 8500 ft (just 0.4 mile south of the Marion Mountain Trail junction). Although snow cover still averages about 90% thereafter all the way to San Jacinto Peak, lengthy bare patches are starting to appear even as high as 10,500 ft in the most sun-exposed areas, and these will expand steadily over the next week. After the Marion junction, the track is well-traveled and compacted to Little Round Valley, almost entirely following the trail route accurately (spikes useful for descending). Above Little Round Valley there are myriad posthole track options, but the most heavily traveled now almost entirely follows the actual trail route. The other, more direct tracks, are now harder to follow as they encounter rocks and vegetation in the rapidly expanding snow-free areas.

Marion Mountain Trail [updated 15th December] is now largely clear of snow to the junction with the PCT/Deer Springs Trail. Nevertheless, two sections of persistent icy snow sections remain, one for about 0.4 mile in the central (most sheltered) portion of the trail, and the other the final 0.1 mile closest to the PCT. Some hikers will find that spikes remain very useful, especially for descending, as some of the icy snow patches are treacherous. The Trail Report removed one new blowdown from the lower trail on 9th, but there is another significant one about 0.7 mile from the top (with a fairly easy workaround).

Seven Pines Trail [updated 15th December] has no tracks to follow through the patchy snow on its uppermost section.

Fuller Ridge Trail (PCT Miles 185.5-190.5) [updated 15th December] has a lightly traveled but accurate posthole track to follow through the remaining 20% snow cover in its most sheltered sections. Sun-exposed areas (notably Miles 186-186.6 and 187.5-188.5) and those closest to Black Mountain Road (north from Mile 189.5) are now clear of snow.

Black Mountain Trail (2E35) was functionally clear of snow by 3rd December, with just a few tiny icy snow patches near the top. Four medium-sized treefall hazards include three within 0.1 mile of one another about 1.5 miles up from the trailhead, plus another just below the top of the trail, but all have easy workarounds. The climbers trail section that continues from the top of the trail to the fire lookout still has about 20% icy snow cover, as does the uppermost access road to the tower.

SNOW DEPTHS

Snow depths measured on 22nd December 2025 (most locations) and 15th December (Deer Springs Trail) are as follows. Current total depth is the first number given, followed (in parentheses) by the total measured in November following the most recent storms. Altitudes and PCT mileages are approximate.

San Jacinto Peak (10811 ft): 0-3 inches (was 17 inches on 24th November)

Little Round Valley (9800 ft): 4-5 inches (was 15-18 inches in late November)

Wellman Divide (9700 ft): 0 inch (was 11 inches on 24th November)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 0 inch (was 12 inches on 24th November)

Fuller Ridge Trail junction with Deer Springs Trail/PCT Mile 185.5 (8900 ft): 2-3 inches (was 10-12 inches in late November)

Long Valley (8500 ft): 0-1 inch (was 8 inches on 24th November)

Saddle Junction/PCT Mile 179 (8070 ft): 0 inch (was 8 inches on 24th November)

Strawberry Junction/PCT Mile 183 (8050 ft): 0 inches (was 6 inches in late November)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inch by 24th November.

A major blocking high pressure system just west of California will continue to generate warm, relatively calm, and extremely dry conditions for our region into the second half of December. There are tentative forecasts suggesting the jet stream may return to Southern California late in December, around 22nd-26th. Three minor snow storms impacted the San Jacinto mountains in nine days in mid November, as discussed in detail in a prior Report (linked here). Since then, temperatures generally well above seasonal have led to rapid snow melt (for the time of year, given the Sun is at its weakest of the year).

The air temperature of 52.2°F (11°C) that I recorded at San Jacinto Peak on Thursday 11th December 2025 shattered (by 3°F) the previous high temperature knowingly recorded at the Peak in the month of December. Forecasts suggest that the new record could even be exceeded again early next week.

Details are given below under Trail Conditions, but most hikers will find that spikes remain useful in many areas above about 9000 ft, although experienced hikers may find they are no longer essential on established trails even well above that elevation. Despite rapid melting, challenging icy patches persist as low as 7700 ft, notably on Devil’s Slide and Marion Mountain trails. Spikes tend to be especially helpful for descending, even when they seem unnecessary for ascending.

Snow depths measured at various locations on the trail system are given near the foot of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow feet deep is often much easier hiking than traversing across just a few inches depth of, for example, angled virgin icy snow. Conversely, just a one inch covering of icy snow at mid-elevations (where there have been many freeze-thaw cycles) can be among the most treacherous surfaces to hike.

Temperatures are forecast to be far above seasonal into the second half of December. Nevertheless, it is (nominally) winter and hikers should be prepared for temperatures near freezing above 10,000 ft elevation, and periodically below freezing when considering wind chill effects. This advisory may be especially important after 20th December. See the Weather section below for my recent observations from San Jacinto Peak.

Black Mountain Road (4S01) closed to vehicle traffic in mid November at the gate 1.7 miles up from Highway 243. Despite being clear of snow it is now expected to remain closed for the winter season, according to Forest Service.

Be bear aware. Although generally rarely reported, at least six individually identifiable Black Bears have been observed in the San Jacinto mountains since 2017 (I have personally encountered at least one annually for the past seven years). A full-sized adult bear with a right ear tag has been seen in multiple locations from Willow Creek to Fern Valley since August (see my video from a trail cam on 14th September available here, and images from Fern Valley in late August in a prior Report linked here). A smaller, second individual has been reliably reported at least twice, most recently in late September in lower Fern Valley. My brief videos from Devil’s Slide Trail in September 2021 (linked here) and one walking past our house in 2018 (linked here) show two further individuals. There have been no reports of negative interactions with humans in the high country, at or near campsites, or on trails, but bear-safe storage of food when camping is recommended.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (much more frequently during stormy weather and in winter), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures were well above seasonal in the last week of November, and following a few days of cooler seasonal temperatures on 1st-4th, they again warmed to well above average starting Friday 5th. Temperatures are forecast to remain far above seasonal until 20th December, after which there is a possibility that the current “blocking” high pressure system moves away, allowing the jet stream flow to return to Southern California (although details of possible precipitation remain unclear at this time).

The second, third, and fourth storm systems of winter 2025/26 all impacted the San Jacinto mountains in quick succession, on 14th-16th, 17th-18th, and 20th-22nd November, respectively. All three storms were relatively mild, with high freeze levels and very limited snow below 7000 ft. The storm sequence and precipitation outcomes were described in detail in an earlier Report (linked here).

At San Jacinto Peak (10,811ft/3295m) on Thursday 11th December 2025 at 0830 the air temperature was 52.2°F (11°C), with a “windchill” temperature of 48.4°F (9°C), 15% relative humidity, and a barely discernable SE wind sustained at 2 mph gusting to 3.5 mph. This is the first time I have ever recorded an air temperature exceeding 50°F in December at the Peak, and this is undoubtedly a record high for the month at that location.

At the Peak on Tuesday 9th December 2025 at 0750 the air temperature was 40.5°F (5°C), with a windchill temperature of 29.5°F (-1°C), 16% relative humidity, and a persistent NNE wind sustained at 15 mph gusting to 21.6 mph.

At the Peak on Monday 8th December 2025 at 0820 the air temperature was 37.2°F (3°C), with a windchill temperature of 28.0°F (-2°C), 31% relative humidity, and a light NNW wind sustained at 4 mph gusting to 10.5 mph.

At the Peak on Thursday 4th December 2025 at 0840 the air temperature was 24.5°F (-4°C), with a windchill temperature of 8.2°F (-13°C), 13% relative humidity, and a remarkably steady NE wind sustained at 15 mph gusting to 17.7 mph.

TRAIL CONDITIONS

All trails above about 8500 ft remain largely snow-covered (details below), although the frequency and extent of snow-free patches has increased rapidly this week. With above seasonal temperatures almost continuously since 24th November, melting has been unusually rapid for the time of year, especially on sun-exposed slopes. This melting will accelerate further with unusually warm temperatures forecast for the next week at least.

Spikes can be useful above about 9000 ft, locally as low as 7700 ft, as established trails have become consolidated by hiker traffic and undergone freeze-thaw cycles. They are especially useful for descending parts of heavily traveled tracks where the snow has become compacted and icy (e.g., Devil’s Slide, Wellman, Peak, Round Valley, Marion Mountain, and uppermost Deer Springs trails).

Snow depths are marginally suitable for snowshoes above about 9500 ft, but only for off-trail travel. They are no longer useful on established high country trails which are all now heavily compacted. Snow depths everywhere are dropping steadily, and snowshoes will be of little or no use, even off-trail, by mid December.

Devil’s Slide Trail [updated 11th December] is clear of icy snow to about 7700 ft. Above that elevation average ice cover is now only 20% to Saddle Junction. Nevertheless some of the small, persistent, icy snow patches are treacherous, especially those closest to Saddle Junction, and many hikers will continue to find traction devices are helpful on the uppermost trail, especially for descending.

There is a well-traveled, compacted track on the PCT south from Saddle Junction to Chinquapin Flat/PCT Mile 178 [updated 11th December]. Snow cover has dropped markedly this week, to about 80%.

The section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [updated 13th December] now has a well-traveled track to follow through the angled icy snow. These icy slopes on the north side of Tahquitz Peak are notoriously treacherous, and see no direct sunlight in December and January, so conditions change very slowly at this time of year. Spikes are recommended for most hikers, but even then the route will not be comfortable for all (photo below).

South Ridge Trail south of Tahquitz Peak [updated 13th December] is functionally clear of snow to Tahquitz Peak, with a limited number of small icy patches remaining mainly above 8500 ft (switchback 9). Most hikers will find spikes are no longer needed.

There is a lightly-traveled posthole track to follow through shallow and rapidly melting snow on the Strawberry Trail (PCT Miles 180.8-183). The bulk of this trail is very sun-exposed and snow cover now averages only 10% on this trail.

Willow Creek Trail [updated 11th December] has a lightly traveled track to follow through shallow and patchy snow to Skunk Cabbage Meadow. Thereafter the trail is largely clear of snow to Hidden Divide.

There are well-traveled and compacted tracks on Round Valley Trail through Long and Round valleys to Wellman Divide, and on the “Sid Davis” route, the latter emerging at the Peak Trail near 10,000 ft [updated 11th December]. Both routes are starting to have extensive bare patches appear in their most exposed sections.

The PCT north from Saddle Junction [updated 11th December] is now largely clear of snow to 9000 ft elevation, with just a few small icy snow patches persisting on this very sun-exposed south-facing slope. From 9000 ft, where the trail enters forest, there is a well-traveled, compacted, track through light snow cover (now about 90%) to Annie’s Junction and north onto the Wellman Trail.

The Wellman Trail [updated 11th December] averages only about 30% snow cover, concentrated in the most forested sections. The remaining, sun-exposed, areas are clearing rapidly.

The Peak Trail [updated 11th December] has a well-traveled, compacted, track through 90% snow cover that accurately follows the trail route. Several snow-free patches have appeared in the past few days, and these will expand considerably in the next week. There is a split in hiker traffic – as is traditional in winter – near Miller Peak at 10,400 ft, with two equally prominent tracks, one taking the East Ridge on a somewhat meandering (but well-compacted) route to San Jacinto Peak, and the Peak Trail itself above 10,400 ft now having a defined but often lumpy posthole track to follow (photo above). Trails just below San Jacinto Peak proper have largely consolidated into 3-4 alternate routes, all of which ultimately reach the peak. Most hikers are clearly using spikes on this trail, but they are no longer essential for those with extensive experience of snow hiking.

Deer Springs Trail [updated 9th December] is clear of snow to Strawberry Junction. Above Strawberry Junction snow cover has rapidly thinned and largely cleared to 8500 ft (just 0.5 miles south of the Marion Mountain Trail junction). Although snow cover averages 90% thereafter all the way to San Jacinto Peak, lengthy bare patches are starting to appear even as high as 9650 ft in the most sun-exposed areas, and these will expand steadily over the next week or two. Where snow remains between Strawberry Junction and the top of Marion Mountain Trail (approx. PCT Miles 183-185) there is only a moderately traveled posthole track but the snow is thin and easy underfoot. After the Marion junction, the track is well-traveled and compacted to Little Round Valley, almost entirely following the trail route accurately (spikes useful for descending). Above Little Round Valley there are myriad posthole track options, one of which largely follows the actual trail route, but it is rarely the most heavily traveled, most compacted, or indeed the best option, but eventually all the tracks seem to ultimately make their way up towards the Peak (example photo below).

Marion Mountain Trail [updated 9th December] is completely clear of snow to 7700 ft, a little above midway to the junction with the PCT/Deer Springs Trail. In the upper half of the trail snow cover now averages only 30%, but note that some of the persistent snow sections are lengthy and very icy. Spikes remain very useful, especially for descending, as some of the icy snow patches are treacherous. The Trail Report removed one new blowdown from the lower trail on 9th, but there is another significant one about 0.7 mile from the top (with a fairly easy workaround).

Seven Pines Trail [updated 9th December] has no tracks to follow through the snow on its upper section.

Fuller Ridge Trail (PCT Miles 185.5-190.5) [updated 9th December] has a lightly traveled but accurate posthole track to follow through the remaining 30% snow cover in its most sheltered sections. Sun-exposed areas (notably Miles 186-186.6 and 187.5-188.5) and those closest to Black Mountain Road (north from Mile 189.5) are now functionally clear of snow.

Black Mountain Trail (2E35)[updated 3rd December 2025] is functionally clear of snow, with just a few tiny icy snow patches near the top. Four medium-sized treefall hazards include three within 0.1 mile of one another about 1.5 miles up from the trailhead, plus another just below the top of the trail, but all have easy workarounds. The climbers trail section that continues from the top of the trail to the fire lookout still has about 40% icy snow cover, as does the uppermost access road to the tower.

SNOW DEPTHS

Snow depths measured on 9th December (Deer Springs Trail locations) and 8th December 2025 (elsewhere) are as follows. Current total depth is the first number given, followed (in parentheses) by the total measured in November following the most recent storms. Altitudes and PCT mileages are approximate.

San Jacinto Peak (10811 ft): 7-8 inches (was 17 inches on 24th November)

Little Round Valley (9800 ft): 5-7 inches (was 15-18 inches in late November)

Wellman Divide (9700 ft): 1-2 inches (was 11 inches on 24th November)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 2 inches (was 12 inches on 24th November)

Fuller Ridge Trail junction with Deer Springs Trail/PCT Mile 185.5 (8900 ft): 5 inches (was 10-12 inches in late November)

Long Valley (8500 ft): 2-3 inches (was 8 inches on 24th November)

Saddle Junction/PCT Mile 179 (8070 ft): 0-2 inches (was 8 inches on 24th November)

Strawberry Junction/PCT Mile 183 (8050 ft): 0 inches (was 6 inches in late November)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inch by 24th November.

Three minor snow storms impacted the San Jacinto mountains in nine days in mid November, as discussed in detail in the previous Report (linked here). Since then, a week of above seasonal temperatures has led to relatively rapid melting (for the time of year). Although this week is cooling to about seasonal, further dry, warm, weather is expected to return and persist into mid December, with currently no significant additional precipitation in the forecasts.

Details are given below under Trail Conditions, but spikes remain valuable in many areas above about 8000 ft, although experienced hikers may find they are no longer essential on established trails even well above that elevation. Despite rapid melting, treacherous icy patches persist as low as 7700 ft, notably on Devil’s Slide and Marion Mountain trails. Spikes tend to be especially helpful for descending, even when they are unnecessary for ascending. Snow depths are locally suitable for snowshoes above about 9500 ft, but generally only off-trail. They are no longer useful on established trails which are now heavily compacted (and hence ideal for spikes) such as Round Valley Trail, Peak Trail, Wellman Trail, and the posthole route on upper Deer Springs Trail.

Snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow feet deep is often much easier hiking than traversing across just a few inches depth of, for example, angled virgin icy snow. Conversely, just a one inch covering of icy snow at mid-elevations (where there have been many freeze-thaw cycles) can be the most treacherous surface to hike.

Temperatures are forecast to be generally above seasonal into mid December. Nevertheless, hikers should be prepared for temperatures near or below freezing above 10,000 ft elevation, and at times well below freezing when considering wind chill effects, the latter in particular during the passage of a cold front to the north on 3rd-4th December. See the Weather section below for my recent observations from San Jacinto Peak.

Be bear aware. Although generally rarely reported, at least six individually identifiable Black Bears have been observed in the San Jacinto mountains since 2017 (I have personally encountered at least one annually for the past seven years). A full-sized adult bear with a right ear tag has been seen in multiple locations from Willow Creek to Fern Valley since August (see my video from a trail cam on 14th September available here, and images from Fern Valley in late August in a prior Report linked here). A smaller, second individual has been reliably reported at least twice, most recently in late September in lower Fern Valley. My brief videos from Devil’s Slide Trail in September 2021 (linked here) and one walking past our house in 2018 (linked here) show two further individuals. There have been no reports of negative interactions with humans in the high country, at or near campsites, or on trails, but bear-safe storage of food when camping is recommended.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (much more frequently during stormy weather and in winter), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures were well above seasonal in the last week of November, and following a few seasonal days on 1st-4th, will again be well above average starting Friday 5th, then potentially far above average on 8th-12th December. During the latter period, temperatures will be especially mild in the high country (more akin to early April than early December), and melting of snow is expected to be steady throughout, and rapid on sun-exposed slopes.

The second, third, and fourth storm systems of winter 2025/26 all impacted the San Jacinto mountains in quick succession, on 14th-16th, 17th-18th, and 20th-22nd November, respectively. All three storms were relatively mild, with high freeze levels and very limited snow below 7000 ft. The storm sequence and precipitation outcomes were described in detail in the previous Report (linked here).

All three storms underperformed their snow forecasts, but given the climate change crisis, any snow on the ground prior to December should probably be considered something of a bonus. Indeed, at 18.5 inches total snowfall at San Jacinto Peak by the end of November 2025, this winter is second only to 2019/20 in the past eight years for the most snowfall before 1st December (some may remember the spectacular Thanksgiving storm of 2019 that produced almost three feet of snow in three days in late November that year).

At San Jacinto Peak (10,811ft/3295m) on Thursday 4th December 2025 at 0840 the air temperature was 24.5°F (-4°C), with a windchill temperature of 8.2°F (-13°C), 13% relative humidity, and an exceptionally steady NE wind sustained at 15 mph gusting to 17.7 mph.

At the Peak on Monday 1st December 2025 at 0840 the air temperature was 30.6°F (-1°C), with a windchill temperature of 22.8°F (-5°C), 44% relative humidity, and a light NNE wind sustained at 2 mph gusting to 5.8 mph.

At the Peak on Saturday 29th November 2025 at 0755 the air temperature was 36.1°F (2°C), with a windchill temperature of 24.4°F (-4°C), 31% relative humidity, and a benign WNW wind sustained at 6 mph gusting to 11.2 mph.

At the Peak on Thursday 27th November 2025 at 0850 the air temperature was 41.6°F (5°C), with a windchill temperature of 35.2°F (2°C), 18% relative humidity, and a steady SE wind sustained at 6 mph gusting to 7.9 mph.

TRAIL CONDITIONS

All trails above about 8500 ft are largely – or above about 9500 ft completely – snow-covered. With above seasonal temperatures since 24th, melting has been unusually rapid, especially on sun-exposed slopes.

Spikes can be useful above about 8000 ft, locally somewhat lower, as established trails have become consolidated by hiker traffic and undergone freeze-thaw cycles. They are especially useful for descending heavily traveled tracks where the snow has become compacted and icy (e.g., Devil’s Slide, Wellman, Peak, Round Valley, and uppermost Deer Springs trails).

Snow depths are locally suitable for snowshoeing above 9500 ft, but only off-trail or when breaking trail on routes that have so far been largely untraveled. Snow depths are dropping steadily, and snowshoes will be of very limited use by the second week of December.

Devil’s Slide Trail [updated 4th December] is functionally clear of icy snow to about 7700 ft. Above that elevation, there is a heavily compacted and icy track to follow through increasingly patchy thin snow (average ice cover now only 30% to Saddle Junction). Some hikers will find that traction devices are helpful on the upper trail, especially for descending.

There is a well-traveled, compacted track on the PCT south from Saddle Junction to Chinquapin Flat/PCT Mile 178 [updated 4th December]. The track is somewhat less well traveled and requires some minor postholing about 0.3 mile from Chinquapin Flat.

The section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [updated 6th December] now has a well-traveled track to follow through the angled icy snow, with significant compaction over the holiday weekend in late November, plus minor melting. Some of the track remains covered by fallen ice. These icy slopes on the north side of Tahquitz Peak are notoriously treacherous. Spikes are recommended for most hikers, but even then the route will not be comfortable for all (photo below).

South Ridge Trail south of Tahquitz Peak [updated 6th December] is functionally clear of snow to 8500 ft (switchback 9) with just a couple of tiny icy patches below that elevation. Thereafter icy snow cover averages about 40% to Tahquitz Peak, but it is diminishing rapidly with coverage having halved in the past four days. Some hikers will find spikes useful for descending the upper trail.

As of Sunday 30th November, there is a simple posthole track to follow through shallow and rapidly melting snow on the Strawberry Trail (PCT Miles 180.8-183). The bulk of this trail is very sun-exposed and snow cover averages only 30% on this trail.

Willow Creek Trail [updated 1st December] has a lightly traveled track to follow through shallow and patchy snow, at least to Skunk Cabbage Meadow.

There are well-traveled and compacted tracks on Round Valley Trail through Long and Round valleys to Wellman Divide, and on the “Sid Davis” route, the latter emerging at the Peak Trail near 10,000 ft [updated 4th December].

The PCT north from Saddle Junction, continuing onto the Wellman Trail, has a well-traveled and increasingly compacted track through light snow cover to Wellman Divide [updated 1st December]. Melting has been rapid on the most sun-exposed section immediately north of Saddle Junction (“Angel’s Glide”) with some lengthy snow-free sections already appearing, and the first mile north of Saddle Junction now averages only 50% snow cover.

The Peak Trail [updated 4th December] has a well-traveled, compacted, posthole track through continuous snow cover that accurately follows the trail route to near Miller Peak at 10,400 ft. Thereafter there is a split in hiker traffic – as is traditional in winter – with two equally prominent tracks, one taking the East Ridge on a somewhat meandering route to San Jacinto Peak, and the Peak Trail itself above 10,400 ft now having a defined compacted track to follow. Trails just below San Jacinto Peak proper are starting to consolidate into less of a shambolic maze of alternate routes, but there has been some infilling with spindrift in strong winds on 3rd-4th December, reducing the visibility of some tracks, notably that on the East Ridge.

Deer Springs Trail [updated 4th December] is clear of snow to Strawberry Junction. Above Strawberry Junction snow cover has rapidly thinned and is increasingly patchy to 8500 ft (about 0.5 miles south of the Marion Mountain Trail junction). Although snow cover is functionally continuous thereafter all the way to San Jacinto Peak, small bare patches are starting to appear even as high as 9650 ft. There is only a moderately traveled posthole track between Strawberry Junction and the top of Marion Mountain Trail (approx. PCT Miles 183-185), but the snow is thin and easy underfoot. After the Marion junction, the track is well-traveled and compacted to Little Round Valley, almost entirely following the trail route accurately (spikes useful for descending). Above Little Round Valley there are multiple posthole track options, none of which consistently follow the actual trail route, most of which ascend steeply, some of which are more heavily traveled than others, but all of which seem to ultimately make their way up towards the Peak (example photo below).

Marion Mountain Trail [updated 4th December] is completely clear of snow to 7600 ft, roughly midway to the junction with the PCT/Deer Springs Trail. In the upper half of the trail snow cover averages 60%, with extensive bare patches in the most sun-exposed areas, but also some lengthy and very icy sections too. Spikes are very useful, especially for descending.

Seven Pines Trail [updated 4th December] has no tracks to follow through the snow on its upper section.

Fuller Ridge Trail [updated 4th December] has a lightly traveled but accurate posthole track to follow through light snow cover along its entire length (PCT Miles 185.5-190.5). Sun-exposed areas (notably Miles 187.5-188.5) and those closest to Black Mountain Road (Mile 190 north) are now largely clear of snow.

Black Mountain Trail (2E35)[updated 3rd December 2025] is functionally clear of snow, with just a few tiny icy snow patches near the top. Four medium-sized treefall hazards include three within 0.1 mile of one another about 1.5 miles up from the trailhead, plus another just below the top of the trail, but all have easy workarounds. The climbers trail section that continues from the top of the trail to the fire lookout still has about 40% icy snow cover, as does the uppermost access road to the tower.

SNOW DEPTHS

Snow depths measured on 1st December 2025 are as follows. Current total depth is the first number given, followed (in parentheses) by the total measured on 24th November following the most recent storms. Altitudes and PCT mileages are approximate.

San Jacinto Peak (10811 ft): 11-12 inches (17 inches on 24th November)

Wellman Divide (9700 ft): 5 inches (was 11 inches on 24th)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 10 inches (was 12 inches on 24th)

Long Valley (8500 ft): 3-4 inches (was 8 inches on 24th)

Saddle Junction/approx. PCT Mile 179 (8070 ft): 3-4 inches (was 8 inches on 24th)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inch by 24th November.

Details are given below under Trail Conditions, but carrying spikes is now generally advisable everywhere above about 8000 ft. Despite rapid melting, treacherous icy patches persist as low as 7700 ft, notably on Devil’s Slide Trail. Spikes tend to be especially helpful for descending, even when they do not seem necessary for ascending. Snow depths are currently suitable for snowshoes above about 9000 ft, but they are only of use on untraveled trails and off-trail. They are no longer useful on established trails which are now heavily compacted (and hence ideal for spikes) such as Round Valley Trail, Peak Trail, Wellman Trail, and the posthole route on upper Deer Springs Trail.

The second, third, and fourth storm systems of winter 2025/26 all recently impacted the San Jacinto mountains in quick succession, on 14th-16th, 17th-18th, and 20th-22nd November, respectively. More detail on each is given in the Weather section below.

All three storms underperformed their snow forecasts, but given the climate change crisis, any snow on the ground prior to December should probably be considered something of a bonus. Indeed, at 18.5 inches total snowfall at San Jacinto Peak by the end of November 2025, this winter is second only to 2019/20 in the past eight years for the most snowfall before 1st December (some may remember the spectacular Thanksgiving storm of 2019 that produced almost three feet of snow in three days in late November that year).

The most recent storm resulted in arguably the biggest weather forecasting error in the past decade in these mountains, when the first wave of the storm late on Friday 21st November produced only four inches of snow at San Jacinto Peak, in contrast to the 10-25 inches that was widely predicted. The situation was partially salvaged when the rotational movement of the system brought it back around on Saturday 22nd, this time coming in from easterly directions, with locations on the east slope, including the Peak, receiving 3-4 more inches. The easterly winds accompanying the rotation were strong and especially gusty, resulting in prodigious drifting.

Snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow feet deep is often much easier hiking than traversing across just a few inches depth of angled virgin icy snow.

Temperatures are now expected to be above seasonal into early December. Nevertheless, hikers should be prepared for temperatures near freezing above 10,000 ft elevation, and below freezing when considering wind chill effects, in particular around 4th and 7th-8th December. At this time, the next possible precipitation is tentatively forecast for 3rd-4th December. See the Weather section below for my recent observations from San Jacinto Peak.

Be bear aware. Although generally rarely reported, at least six individually identifiable Black Bears have been observed in the San Jacinto mountains since 2017 (I have personally encountered at least one annually for the past seven years). A full-sized adult bear with a right ear tag has been seen in multiple locations from Willow Creek to Fern Valley since August (see my video from a trail cam on 14th September available here, and images from Fern Valley in late August in a prior Report linked here). A smaller, second individual has been reliably reported at least twice, most recently in late September in lower Fern Valley. My brief videos from Devil’s Slide Trail in September 2021 (linked here) and one walking past our house in 2018 (linked here) show two further individuals. There have been no reports of negative interactions with humans in the high country, at or near campsites, or on trails, but bear-safe storage of food when camping is recommended.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (much more frequently during stormy weather and in winter), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Three storm systems impacted the San Jacinto mountains in nine days from 14th-22nd November. All three storms were relatively mild, with high freeze levels and very limited snow below 7000 ft.

An “atmospheric river” on 14th-16th started extremely warm for the season, with a freeze level initially above 11,000 ft and rain throughout the highest peaks for the first day of the storm, before turning to snow early on Saturday 15th. Even then, the snow level remained high, with little more than a dusting below 7000 ft. This warmth of course limited snow at all elevations, with seven inches at San Jacinto Peak, down to three inches at Saddle Junction (8100 ft). Accumulated rainfall was impressive at mid elevations, with 2.70 inches in Idyllwild (at 5550 ft).

The system on 17th-18th was colder, with a freeze level dropping to 6000 ft. However this cooling happened largely after the passage of the main precipitation, so snowfall at mid elevations was extremely limited, with just one inch at Humber Park (6500 ft)(which lasted only hours before melting) and barely a dusting below that. Fresh snowfall in the high country was more limited than the prior storm (four inches at San Jacinto Peak), but more uniformly distributed across all elevations above 8000 ft (2-4 inches throughout). Rainfall in Idyllwild was 0.51 inch.

The third system, on 20th-22nd, initially moved across the region from the south-west. Universally forecast to produce heavy snow, in the San Jacinto mountains the accumulation rate of 0.25 inch/hour at the highest elevations overnight on 20th produced only four inches by first light the next day as the storm moved away, with a dusting down to 6500 ft. Thankfully the rotation of the system brought it back around from the east with a vengeance the next day, with fine snowfall accompanied by sustained winds of 20 mph with gusts nearly double that speed. Snowfall accumulation on 22nd roughly matched that on 20th-21st, especially on the eastern slope of the mountain (e.g,, from Red Tahquitz to Long Valley, including the east flanks of the high peaks), with three inches at San Jacinto Peak for a nine day total accumulation of 17-18 inches.

Temperatures are rising rapidly to above seasonal this week, especially at upper elevations. This is expected to result in steady snowmelt at all elevations, and consequent deterioration in trail conditions of snowy tracks. Minor storm systems provisionally forecast to arrive overnight on Saturday 29th November and another on 3rd-4th December now look like to pass too far to the north to impact the San Jacinto mountains, other than causing brief and modest drops in temperatures.

At San Jacinto Peak (10,811ft/3295m) on Saturday 29th November 2025 at 0755 the air temperature was 36.1°F (2°C), with a windchill temperature of 24.4°F (-4°C), 31% relative humidity, and a benign WNW wind sustained at 6 mph gusting to 11.2 mph.

At the Peak on Thursday 27th November 2025 at 0850 the air temperature was 41.6°F (5°C), with a windchill temperature of 35.2°F (2°C), 18% relative humidity, and a steady SE wind sustained at 6 mph gusting to 7.9 mph.

At the Peak on Monday 24th November 2025 at 0910 the air temperature was 35.5°F (2°C), with a windchill temperature of 25.0°F (-4°C), 47% relative humidity, and a light NNE wind sustained at 4 mph gusting to 10.2 mph.

At the Peak on Friday 21st November 2025 at 0820 the air temperature was 18.7°F (-7°C), with a windchill temperature of 1.9°F (-17°C), 56% relative humidity, and a cool SSW wind sustained at 11 mph gusting to 14.8 mph.

TRAIL CONDITIONS

All trails above about 8000 ft are largely – or above 9000 ft completely – snow-covered. With above seasonal temperatures since 24th, melting has been unusually rapid, especially on sun-exposed slopes.

Spikes can be useful everywhere above about 8000 ft, locally lower in places, as established trails have become consolidated by hiker traffic and undergone freeze-thaw cycles. They are especially useful for descending heavily traveled trails where they have become compacted and icy (e.g., Devil’s Slide, Wellman, Peak, and Round Valley trails).

Snow depths are suitable for snowshoeing above 9000 ft, but only off-trail or when breaking trail on routes that have so far been untraveled.

Devil’s Slide Trail [updated Saturday 29th] is functionally clear of icy snow to about 7600 ft. Above that elevation, there is a heavily compacted and icy track to follow through increasingly patchy thin snow (average snow cover now 50% to Saddle Junction). Most hikers will find that traction devices are very helpful on the upper trail, especially for descending.

There is a well-traveled, compacted track most of the way on the PCT south from Saddle Junction to Chinquapin Flat/PCT Mile 178 [updated Wednesday 26th]. The track is less well traveled and requires some minor postholing about 0.3 mile from Chinquapin Flat.

The section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [updated Wednesday 26th] currently has a lightly traveled, uneven track to follow through the angled icy snow. Much of the track is covered by fallen ice. These icy slopes on the north side of Tahquitz Peak are notoriously treacherous. Currently spikes (with hiking poles at a minimum) are strongly recommended, but the route is probably not suitable for most hikers (photo above).

South Ridge Trail [updated Wednesday 26th] is clear of snow to 0.5 mile beyond Old Lookout Flat to about 7800 ft. Snow cover is increasingly patchy to 8500 ft, but the patches are invariably icy. There is a well-defined but icy track through continuous snow above 8500 ft to Tahquitz Peak. Rocks around the Peak are also largely icy, but the tower is now almost completely clear of ice. Spikes are recommended for the upper trail.

As of Saturday 29th, there were no tracks to follow through shallow and rapidly melting snow on the Strawberry Trail (PCT Miles 180.8-183).

Willow Creek Trail [updated Saturday 29th] now has a lightly traveled track to follow through shallow and patchy snow, at least to Skunk Cabbage Meadow.

There are well-traveled and compacted tracks on Round Valley Trail through Long and Round valleys to Wellman Divide, and on the “Sid Davis” route, the latter emerging at the Peak Trail near 10,000 ft [updated Saturday 29th].

The PCT north from Saddle Junction, continuing onto the Wellman Trail, has a well-traveled and increasingly compacted track through light to moderate snow cover to Wellman Divide [updated Saturday 29th]. Melting has been rapid on the most sun-exposed section immediately north of Saddle Junction (“Angel’s Glide”) with some lengthy snow-free sections already appearing.

The Peak Trail [updated Saturday 29th] has a well-traveled, compacted, posthole track through continuous snow cover that accurately follows the trail route to near Miller Peak at 10,400 ft. Thereafter the majority of hiker traffic – as is traditional in winter – takes the East Ridge on a meandering route to San Jacinto Peak. The Peak Trail itself above 10,400 ft has seen more traffic this weekend, but remains a more uneven postholing route. Tracks just below San Jacinto Peak proper are starting to consolidate into less of a shambolic maze of alternate routes, but it is still easy to wander well off track on less obvious options.

Deer Springs Trail [updated Thursday 27th] is functionally clear of snow to Strawberry Junction, with just a few tiny patches of soft snow close to the junction (spikes not required). Above Strawberry Junction snow cover is very thin and increasingly patchy to 8500 ft, becoming functionally continuous thereafter all the way to San Jacinto Peak. There is only a very lightly traveled posthole track between Strawberry Junction and the top of Marion Mountain Trail (approx. PCT Miles 183-185), but the snow is thin and easy underfoot. After the Marion junction, the track is well-traveled and compacted to Little Round Valley, almost entirely following the trail route accurately (spikes useful, mainly for descending). Above Little Round Valley there are two options, a lightly traveled and uneven posthole track that ascends steeply (as is traditional in winter), or my snowshoe track that largely follows the trail route. The latter (photograph below) is an easier ascent, but only if followed with snowshoes (or skis), as it would otherwise involve severe postholing.

Marion Mountain Trail [updated Thursday 27th] has a well-traveled and compacted track that accurately follows the trail route through the snow on its upper section. Patchy snow cover starts at 7000 ft and is largely continuous above 7500 ft, with bare patches higher in the most sun-exposed areas. Spikes are useful, especially for descending.

Seven Pines Trail [updated Thursday 27th] has no tracks to follow through the snow on its upper section.

Fuller Ridge Trail [updated Thursday 27th] has a lightly traveled but accurate posthole track to follow through light-to-moderate snow cover along its entire length (PCT Miles 185.5-190.5).

SNOW DEPTHS

Snow depths measured on 24th November 2025 are as follows. Current total depth is the first number given, followed (in parentheses) by details of the snowfall in the storm of 21st-22nd November. For details of the snowfall in the two preceding storms see the prior Report (linked here). Altitudes and PCT mileages are approximate. [Update on Saturday 29th November: all of these locations have lost 20-40% of these depths to melting in the past five days. I expect to issue revised measurements on Monday 1st December.]

San Jacinto Peak (10811 ft): 17-18 inches (4 inches added by 21st November, plus three on 22nd)

Wellman Divide (9700 ft): 11 inches (4 inches new on 21st-22nd)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 12 inches (6 inches new on 21st-22nd)

Long Valley (8500 ft): 8 inches

Saddle Junction/approx. PCT Mile 179 (8070 ft): 8 inches (3 inches new on 21st-22nd)

Devil’s Slide Trail at Humber Park (6550 ft): 0 inch on 24th, with single inches on 18th and 21st already completely melted

Idyllwild (at 5550 ft): 0 inch snow, 0.56 inch rain 21st-23rd November

UPDATE Saturday 22nd November 2025 at 1150: as seems to be more frequent in recent years, the rotational movement of yesterday’s storm system has brought it back around, this time coming in from easterly directions. Consequently the east side of the range has received modest snowfall this morning, with about four inches in Long Valley (for a total depth of about eight inches). The highest elevations remained above the cloud for much of the morning. The easterly winds have been strong and very gusty, resulting in extensive drifting, and unfortunately the (at least partial) removal of tracks broken yesterday. We broke trail up South Ridge this morning to Tahquitz Peak, from where I recorded a short video report (linked here). The snow level remained high at about 7000 ft, with just light drizzle in Idyllwild, and total accumulation at Tahquitz is a modest 4-6 inches, but this is obscured by severe drifting everywhere above about 8000 ft. Further fresh snow is possible this afternoon.

UPDATE Friday 21st November 2025: in the biggest weather forecasting error in the past decade in these mountains, the storm overnight – our third in eight days – that was widely forecast to produce 10-25 inches of snow around the highest peaks instead resulted in only three inches at San Jacinto Peak, with one inch at both Saddle Junction and Long Valley, and barely a dusting below 7000 ft. It was however a gorgeous morning in the high country, as seen in a short video report I recorded from San Jacinto Peak early today (linked here). As of this morning, well-defined, accurate tracks are in place on Devil’s Slide Trail, north from there via the Wellman and Peak trails to San Jacinto Peak, and also on the Round Valley Trail from Long Valley to Wellman Divide (broken above 9000 ft with snowshoes by myself and Kyle Eubanks). Spikes are useful everywhere above about 8000 ft, potentially lower in places. While we both used snowshoes this morning above about 9000 ft, they will not be required even above that elevation on traveled tracks (they would however be useful on upper Deer Springs Trail, which does not have a freshly broken track as of Friday morning).

————————————–

This is a summary of conditions following the second and third storm systems of winter 2025/26 that impacted the San Jacinto mountains on 14th-16th and 17th-18th November, respectively. I recorded a video report from San Jacinto Peak on the morning on Tuesday 18th (linked here) which gives a feel for current conditions in the high country.

This Report is intentionally brief as the next storm system, the third in a week, arrives late on Thursday 20th with precipitation expected to last into Saturday 22nd November. That storm will again be relatively cool, similar to the storm on 17th-18th, with a freeze level dropping to near 6000 ft, and potentially two feet of snow forecast above 10,000 ft elevation. Consequently snow and trail conditions are expected to change markedly again by Saturday 22nd, although the changes should be limited to upper elevations, with predominantly rain expected below about 6500 ft.

Both of the recent storms were ultimately less impactful than forecasts had suggested, partly due to the difficulty of predicting the exact paths of complex rotating “atmospheric rivers”, and partly because the first storm was so mild that the very high freeze level significantly restricted the quantity of snowfall (it rained all the way up to San Jacinto Peak for the first 20 hours of the storm throughout 14th November). It is interesting to speculate that if the front of that earlier storm system had been just a couple of degrees colder, with a freeze level consequently hundreds of feet lower overnight on Friday 14th, the snow depth around the highest peaks could easily have been double what we ultimately experienced.

Further details are given below under Trail Conditions, but in summary, carrying spikes is now recommended everywhere above about 7500 ft. Snow depths are currently marginal anywhere for snowshoes, although they could be used above about 9500 ft on untraveled trails. That advice is expected to change by Saturday 22nd with significant additional fresh snowfall.

Details of snow depths measured at various locations on the trail system are given towards the end of this posting. Note however that snow depth itself is rarely indicative of the difficulty (or ease) of hiking a particular track or trail. For example a firm, well-compacted track across snow several feet deep is often much easier hiking than traversing across just a few inches depth of angled virgin icy snow.

Below seasonal temperatures followed the passage of the storm system on Tuesday 18th November and will persist until Sunday 23rd. Hikers must be prepared for temperatures well below freezing at higher elevations, and far below freezing when considering wind chill effects. See the Weather section below for my recent observations from San Jacinto Peak.

Be bear aware. Although generally rarely reported, at least six individually identifiable Black Bears have been observed in the San Jacinto mountains since 2017 (I have personally encountered at least one annually for the past seven years). A full-sized adult bear with a right ear tag has been seen in multiple locations from Willow Creek to Fern Valley since August (see my video from a trail cam on 14th September available here, and images from Fern Valley in late August in a prior Report linked here). A smaller, second individual has been reliably reported at least twice, most recently in late September in lower Fern Valley. My brief videos from Devil’s Slide Trail in September 2021 (linked here) and one walking past our house in 2018 (linked here) show two further individuals. There have been no reports of negative interactions with humans in the high country, at or near campsites, or on trails, but bear-safe storage of food when camping is recommended.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (more frequently during stormy weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

The second storm system of the season (and the first since 14th October) impacted the region on 14th-16th November. The “atmospheric river” system was extremely warm for the season, with a freeze level initially above 11,000 ft and rain throughout the highest peaks for the first day of the storm, before turning to snow early on Saturday 15th. Even then, the snow level remained high throughout the storm, with little more than a dusting below 7000 ft. Inevitably this limited snow at all elevations, with seven inches at San Jacinto Peak, down to three inches at Saddle Junction (8100 ft). Accumulated rainfall was impressive at mid elevations, with 2.70 inches in Idyllwild (at 5550 ft).

The system on 17th-18th was palpably colder, with a freeze level dropping to 6000 ft. However this rapid cooling happened largely after the passage of the main precipitation, so snowfall at mid elevations was extremely limited, with just one inch at Humber Park (6500 ft)(which lasted only hours before melting) and barely a dusting below that. Fresh snowfall in the high country was more limited than the prior storm (four inches at San Jacinto Peak), but more uniformly distributed across all elevations above 8000 ft (2-4 inches throughout). Rainfall in Idyllwild was 0.51 inch.

The third system in a week, due on 20th-21st, is expected to be similar in temperature to the storm of 17th-18th. with a freeze level near 6000 ft. About one inch of rain is forecast for Idyllwild. Although snow forecasts have varied widely in recent days, at least 10-12 inches, possibly much more, is now expected above 10,000 ft.

Starting Sunday 23rd November, temperatures are tentatively forecast to rise rapidly to above seasonal, especially at upper elevations. This is expected to result in rapid snowmelt at all elevations, and of course consequent steady changes in trail conditions.

The first (very minor) winter storm of the season impacted the region on Tuesday 14th October 2025, as described in detail in a prior Report (linked here).

At San Jacinto Peak (10,811ft/3295m) on Tuesday 18th November 2025 at 0650 the air temperature was 15.9°F (-9°C), with a windchill temperature of -3.7°F (-20°C), 38% relative humidity, and a sharp SSW wind sustained at 14 mph gusting to 20.7 mph.

At the Peak on Monday 17th November 2025 at 1420 the air temperature was 25.0°F (-4°C), with a windchill temperature of 16.0°F (-9°C), 66% relative humidity, and a frigid SW wind sustained at 14 mph gusting to 26 mph.

At the Peak on Friday 14th November 2025 at 1610 the air temperature was 36.0°F (2°C), with a windchill temperature of 23.5°F (-4°C), 100% relative humidity, and a steady due South wind sustained at 14 mph gusting to 17.4 mph.

TRAIL CONDITIONS

All trails above about 7500 ft are largely or completely snow-covered. By the afternoon of 18th, melting was already well underway below 9000 ft. The powder on 18th was so light and fine that drifting in the trails has been dramatic above 9000 ft, which is not reflected in the snow depths given below. Trails above 10,000 ft have snow up to 25 inches deep in the trail routes in places.

Spikes are potentially useful everywhere above about 7500 ft, lower in places, especially as established trails become consolidated by hiker traffic and undergo freeze-thaw cycles. They are especially useful for descending trails when they become icy and compacted (e.g. Devil’s Slide and lower Deer Springs trails). Snow depths are suitable for snowshoeing above 10,000 ft, but this elevation is expected to drop significantly after 22nd November.

Ernie Maxwell Trail is completely clear of snow.

Devil’s Slide Trail has a well-traveled track to follow through largely continuous thin icy snow above 7000 ft.

Deer Springs Trail is largely clear of snow to the Suicide Rock junction with just a few patches close to the junction (spikes not required). Above Strawberry Junction snow cover is continuous, but at this time there is no track to follow to Little Round Valley or beyond to San Jacinto Peak.

SNOW DEPTHS

Snow depths measured on 18th November 2025 are as follows. Current total depth is the first number given, followed (in parentheses) by the snowfall in the storm of 14th-16th November and then the snowfall in the storm of 17th-18th November). Altitudes and PCT mileages are approximate.

San Jacinto Peak (10811 ft): 11 inches (7 inches by 16th November/4 inches added by 18th November)

Wellman Divide (9700 ft): 7 inches (4 inches/3 inches)

Annie’s Junction/PCT Mile 180.8 (9020 ft): 6 inches (3 inches/3 inches)

Saddle Junction/approx. PCT Mile 179 (8070 ft): 5 inches (3 inches/2 inches)

Devil’s Slide Trail at Humber Park (6550 ft): 1 inch on 18th, already completely melted later that day

Idyllwild (village center at 5400 ft): 0 inches

The first significant storms of winter 2025/26 – three systems in eight days – are forecast to impact the San Jacinto mountains from Friday 14th to Friday 21st November 2025.

Please check this page for periodic updates – the most recent is at the top – throughout the multiday storm sequence. The next comprehensive Report update, summarizing conditions during and after the first two of the three storms, is tentatively scheduled for Wednesday 19th.

UPDATE Tuesday 18th November at 0800

The minor storm that moved through swiftly overnight produced a further three inches of snow at San Jacinto Peak – for a total on the ground of about 10 inches – and dusted locally as low as 6000 ft. The snow quality was perfect, a light powder, but that did drift heavily in gusty overnight winds, so tracks are obscured above 10,000 ft and snow in trails can be much deeper than expected.

At this time snow depths are marginal for snowshoes. That is expected to change, at least above about 9500 ft, following the next storm on Friday 21st.

Rainfall in Idyllwild totaled 0.51 inch, with no evidence of snow in Pine Cove (to 6300 ft).

I recorded a video report from San Jacinto Peak early this morning (linked here) which gives a good feel for current conditions.

UPDATE Monday 17th November at 1545

On my afternoon hike, snow conditions were poor and slushy to nearly 9000 ft, before improving above that elevation. Snow depths at Annie’s Junction (9020 ft) and Wellman Divide (9700 ft) are four and five inches, respectively.

At San Jacinto Peak (10,811ft/3295m) on Monday 17th November 2025 at 1515 the air temperature was 24.1°F (-4°C), with a windchill temperature of 5.5°F (-15°C), 72% relative humidity, and a fresh WSW wind sustained at 15 mph gusting to 23.9 mph.

UPDATE Monday 17th November at 1130

There was no further precipitation overnight. The second storm arrives tonight and is forecast to move through relatively quickly overnight, with several inches of additional snow in the high country and just under 0.5 inch of rain at mid elevations.

The current snow level is as low as 7000 ft in Strawberry Valley with a dusting down to 6600 ft. Snow depth increases steadily with three inches at 8000 ft (Saddle Junction) up to seven inches at San Jacinto Peak.

Devil’s Slide Trail for example has largely continuous snow in the trail above 7200 ft, which is currently slushy, but will freeze again overnight.

Carrying spikes is recommended everywhere above about 7000 ft at this time, along with the necessary clothing and equipment for genuine winter conditions. The storm coming in tonight is considerably colder, with high country air temperatures well below freezing and windchills far below freezing for the remainder of this week.

UPDATE Sunday 16th November at 1900

Until it largely stopped at dusk, the rain was almost continuous in Idyllwild today, with an additional 0.84 inch in the past 12 hours for a storm total of 2.70 inches.

Periodic snowfall restarted in the high country by 1200, with the snow level remaining high (>7500 ft), but with only modest accumulation (struggling to reach 0.25 inch/hour) by the time it stopped in mid afternoon.

UPDATE Sunday 16th November at 0940

Periodic rain overnight at mid elevations produced another half inch in Idyllwild, for an impressive storm total at 5550 ft (since Friday 14th) of 1.86 inches by 0700 this morning (and it continues to rain steadily). Light snow overnight and into this morning has added about two inches at the elevation of Long Valley (8500 ft), with total depth at San Jacinto Peak now near six inches. The snow level has remained stubbornly around 7500 ft, with all elevations above that level having added an inch or two of snow since yesterday.

By 0930 it stopped snowing throughout most of the high country, with the cloud cover rapidly clearing on the eastern side of the mountain range. All forecasts are indicating relatively minimal further precipitation today as this first storm system moves away to the east, however rain-producing cloud often remains socked into the west slope valleys long after the high country has cleared.

UPDATE Saturday 15th November at 1830

Apologies for the delayed updating. As described below, it was a challenging day around the Peak. Snowfall at San Jacinto Peak was three inches by early afternoon, likely 4-5 inches by this evening, with two inches at Wellman Divide (9700 ft). There has been a dusting as low as 8000 ft (just below Saddle Junction), with a slushy 0.5 inch from there to 9000 ft elevation.

An additional 0.9 inch of rain in Idyllwild today brings the storm total at 5550 ft to 1.41 inches. Rainfall accumulation at Saddle Junction was 1.29 inches before turning to sleet/light snow.

We dealt with three cases of hypothermia in two separate hiker groups at San Jacinto Peak today, occupying most of the daylight hours. All cases were basically caused by hikers getting wet in the rain on their ascents and then running into the cold, wind, and snow at the highest elevations. Two women I assisted this afternoon exhibited serious symptoms, and I helped get them dry, provided them with extra clothing that I had, made hot beverages, and ultimately guided them part way back down the mountain. The good news is that I have had messages from both groups that everyone eventually got home safely. A tough day, but a great learning experience for those who ventured into the high country today.

UPDATE Saturday 15th November at 0930

The bad news from the top of the mountain is that it rained gently throughout the night at San Jacinto Peak, with the freeze level remaining stubbornly above 11,000 ft. Storm total rainfall by 0700 was 1.09 inches.

The good news is that it steadily turned to snow after 0700, accumulating to 0.75 inch by 0930. Currently the snow level is reported to be around Wellman Divide (9700 ft).

Rainfall storm total in Idyllwild up to 0700 this morning was 0.51 inch.

UPDATE Friday 14th November at 2020

The temperature at San Jacinto Peak has remained around 36°F all day, with consequently no snow but 0.79 inch of rain accumulating by 2015. It is forecast to turn to light snow overnight.

On our hike up this afternoon, there was intermittent light rain at all elevations above 6000 ft.

Total rainfall in Idyllwild in the past 24 hours has been an unexpectedly low 0.28 inch, most of which fell overnight.

UPDATE Friday 14th November at 1030

Rain accumulation overnight by 0700 was 0.20 inch in Idyllwild (at 5550 ft), with 0.05 inch in Long Valley (8500 ft). The start of the system was so mild – well above freezing even above 10,000 ft – that light rain fell at all elevations including around the highest peaks.

The first significant winter storm of the 2025/26 winter will impact the San Jacinto mountains on 14th-16th November. A second storm system will follow so close behind, on 17th-18th, that the gap between the two may be hard to discern, especially at mid elevations where it is expected to rain more-or-less continuously for five days (14th-18th).

The first system will be warm for the season, with initial rainfall potentially above 10,000 ft before the freeze level drops down to around 8000 ft. Rain is expected to persist at mid elevations for at least three days (Friday-Sunday), heaviest on Saturday 15th, and may reach (or even exceed) three inches. Current forecasts indicate 10-15 inches of snow around the highest peaks, mainly focused on the morning of 15th. Due to the warmth of the system, snowfall may be only 4-6 inches at the elevations of Strawberry and Saddle junctions (both around 8000 ft) as these areas will predominantly receive rain. A dusting of snow is possible at elevations as low as Pine Cove and Fern Valley.

Uncertainty persists regarding the second storm system tentatively forecast for 17th-19th. The system is expected to be much colder, with a freeze level dropping as low as 5500 ft, hence light snow in Pine Cove and Idyllwild is more likely. Atmospheric instability continues throughout those days, with a likelihood of periodic light rain at mid elevations (roughly an additional one inch forecast), but snow estimates for the high country have ranged widely from 0-12 inches, with about the middle of that range most likely.

A third storm system tentatively forecast for 20th-21st will also be relatively cold. At this time further light rain is forecast for mid elevations, nut little or no snow for the high country.

Water flows have deteriorated again despite inches of rain in recent months (some example photos below) although this situation may become academic later this week. Most key hiker water sources remain flowing. All ephemeral sources that dried in the summer but temporarily flowed again earlier this month are now dry again. Wellman’s Cienega and the pipe in Round Valley are flowing steadily and will now maintain useable flow into the winter. The creek in Little Round Valley has dried again both where it passes through the meadow and also where it crosses Deer Springs Trail, but continues to flow patchily in its central section. Deer Springs creek (PCT Mile 185.4) dried up in late July where it crosses the trail of the same name, and although it has intermittently flowed again twice during recent rains, is now functionally dry again. The North Fork of the San Jacinto River is flowing where it crosses both Fuller Ridge (PCT Mile 186) and Deer Springs trails, but is largely dry where it crosses Seven Pines Trail. Stone Creek has now dried again where it crosses Deer Springs Trail (near PCT Mile 183.6). Marion Creek is flowing steadily where it crosses the Suicide Rock Trail. Strawberry Cienega (approx PCT Mile 181.9), has dried again.

Willow Creek is flowing weakly again where it crosses the Willow Creek Trail, having dried in August. Hidden Lake functionally dried by the end of June. Long Valley Creek is dry where it passes through Round Valley, as is the nearby creek in Tamarack Valley. Water is flowing reliably in Tahquitz Creek at PCT Mile 177 and again further downstream at the north end of Little Tahquitz Meadow (although it is dry between those two locations)(photos below). The pipe in Tahquitz Meadow dried in mid July. Skunk Cabbage Meadow creek is functionally dry. Middle Spring on Devil’s Slide Trail has been functionally dry since 1st August, but I maintain a tiny pool there from which dogs can drink.

Be bear aware. Although generally rarely reported, at least six individually identifiable Black Bears have been observed in the San Jacinto mountains since 2017 (I have personally encountered at least one annually for the past seven years). A full-sized adult bear with a right ear tag has been seen in multiple locations from Willow Creek to Fern Valley since August (see my video from a trail cam on 14th September available here, and images from Fern Valley in late August in a prior Report linked here). A smaller, second individual has been reliably reported at least twice, most recently in late September in lower Fern Valley. My brief videos from Devil’s Slide Trail in September 2021 (linked here) and one walking past our house in 2018 (linked here) show two further individuals. There have been no reports of negative interactions with humans in the high country, at or near campsites, or on trails, but bear-safe storage of food when camping is recommended.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (more frequently during stormy weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures throughout early November were generally above seasonal at all elevations, with warm, dry (but thankfully weak) easterly winds in recent days. Temperatures cool markedly after Tuesday 11th with the anticipated passage of back-to-back minor winter storms on 13th-19th November.

Winter storm systems are forecast for 14th-16th November (high degree of confidence), 17th-18th November (some uncertainty), and 20th-21st (considerable uncertainty). The first system will be relatively mild, with a freeze level likely above 7000 ft. Steady rain from late Thursday 13th into Sunday 16th is forecast to total at least two inches at mid elevations (e.g., Idyllwild). Currently 8-15 inches of snow are forecast around the highest peaks, but due to the warmth of the system, possibly fewer than six inches at the elevations of Strawberry and Saddle junctions (around 8000 ft).

National Weather Service San Diego published a detailed, revised, video forecast of the upcoming storm system on 12th November (linked here).

The second system on 17th-18th will be colder, with several inches of snowfall mainly on Monday 17th in the high country even though rainfall at mid elevations could be less than one inch, the latter mainly in the afternoon/evening of Monday 17th. Due to the temperature of the storm, light snow is possible at elevations as low as Pine Cove and Fern Valley (a dusting at 5000 ft, 1-3 inches near 6000 ft).

Details remain unclear for the third system, due on 20th-21st, at this time, although it is expected to be as cold as the storm on 17th-18th, but possibly fast moving, and hence with minimal precipitation.

The first (very minor) winter storm of the season impacted the region on Tuesday 14th October. Snow fell intermittently at San Jacinto Peak most of the afternoon, accumulating to about 1.5 inches. Snow dusted as low as 9000 ft, averaging about one inch above 9500 ft. Rainfall in Idyllwild (5550 ft) totaled an impressive 0.76 inch for the day, with 0.85 inch at Saddle Junction (8100 ft).

That storm was a dramatic contrast from the relatively mild, humid, weather experienced since late August. The San Jacinto mountains had a remarkable sequence of tropical and monsoonal autumnal rains spread across ten distinct rain events between 22nd August and 10th October. San Jacinto Peak recorded an impressive 8.74 inches of rainfall, with 4.58 inches recorded in Idyllwild (at 5550 ft).

At San Jacinto Peak (10,811ft/3295m) on Wednesday 12th November 2025 at 1020 the air temperature was 39.9°F (4°C), with a windchill temperature of 28.0°F (-2°C), 48% relative humidity, and a fresh WSW wind sustained at 12 mph gusting to 18.5 mph.

At the Peak on Friday 7th November 2025 at 0945 the air temperature was 46.1°F (8°C), with a windchill temperature of 39.6°F (4°C), 35% relative humidity, and a cool NNE wind sustained at 6 mph gusting to 9.7 mph.

At the Peak on Monday 3rd November 2025 at 0840 the air temperature was 44.1°F (7°C), with a windchill temperature of 36.5°F (2°C), 16% relative humidity, and a remarkably steady SW wind sustained at 9 mph gusting to 10.9 mph.

At the Peak on Friday 31st October 2025 at 0910 the air temperature was 45.3°F (7°C), with a “windchill” temperature of 43.0°F (6°C), 36% relative humidity, and a very light NNE breeze sustained at 0 mph gusting to 3.0 mph.

At the Peak on Wednesday 29th October 2025 at 0945 the air temperature was 56.2°F (13°C), with a “windchill” temperature of 50.7°F (10°C), 30% relative humidity, and a barely discernable NW breeze sustained at 0 mph gusting to 2.2 mph.

TRAIL CONDITIONS

Temperatures will be relatively cold in the high country during the passage of dual storm systems between 13th-19th November. Hikers must be prepared for temperatures well below freezing at higher elevations, and far below freezing when considering wind chill effects, especially on 14th, 15th, 18th, and 19th. It is expected that spikes may be needed above about 9000 ft elevation after 14th.

Trails have cleared of the icy snow that fell three weeks ago. Thankfully most trails suffered relatively minor tread erosion from intense rains in August-October. Neither the Wolf Fire in late June nor the Rosa Fire in early August had major impacts on the trail system, although the latter did burn the southernmost 0.5 mile of the Palm Canyon trail.

For the first time in nearly a decade, Deer Springs Trail from its trailhead to Little Round Valley is now completely clear of blowdowns, with 26 trees removed since the middle of last year (of which 70% were cut by the Trail Report). A joint Eastern Sierra Conservation Corps/State Park crew working in early October trimmed encroaching vegetation along Deer Springs Trail just above the Fuller Ridge Trail junction to about 9300 ft.

On PCT Miles 170-175 (roughly Apache Peak to Red Tahquitz) most blowdowns have been removed but six trees remain to be cut around South Peak (Miles 173.5-174) of which most are significant obstructions for hikers. Sections of the trail are badly overgrown with brush and in their worst condition in decades, especially most of Miles 168-174.

The two large downed trees near PCT Mile 180 were removed by the Trail Report this spring. The Strawberry Trail (PCT Miles 180.8-183.1) has had long-term blowdowns removed this month by Forest Service volunteers. The brush along Miles 181-181.7 has become heavily overgrown since it was last trimmed by the Trail Report in 2021, but there is a plan for trimming work in the next few months.

The maintenance condition of the Fuller Ridge (Miles 185.5-190.5) section of the PCT improved significantly in July 2025, with the Trail Report clearing most of the 15 blowdowns and a PCTA volunteer crew cutting the remainder the following week.

On the Wellman Trail, Wellman’s Cienega is flowing well compared to earlier in the autumn (photo below). The Trail Report continues the work it started last year to keep this trail well-maintained (after it had become badly overgrown by early 2024).

Dark Canyon Road (4S02) had some effective basic maintenance on its dirt section in the spring. The associated Dark Canyon campground is closed for the year (apparently due to federal budget cuts).

For the first time in about 20 years Seven Pines Trail has a continuous route completely cleared of blowdown trees, with the trail also as faithful to the original route as possible. The Trail Report “adopted” Seven Pines as a priority for maintenance work nearly a decade ago due to a disproportionate number of lost hiker rescues (with State Park and Forest Service evidently no longer maintaining the route). Since 2019 we have now removed exactly 100 downed trees – including 25 since April of this year – and the trail is largely trimmed and cleared semi-annually. Although our work has restored this delightful trail, Seven Pines remains a genuine wilderness trail unlike the wider, bare, obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains invaluable for those without extensive experience of hiking this trail.

Black Mountain Road is open and in its typical non-graded condition, i.e. lumpy but readily passable in any moderate clearance vehicle. The tap at Cinco Poses Spring currently has reliable water (located alongside the road 0.2 mile below the Boulder Basin turning).

On Willow Creek Trail whitethorn urgently needs trimming again especially near the boundary between the two agencies. The two large trees remaining uncut in the State Park section from several years ago have easy workarounds.

The Caramba Trail from near Reeds Meadow through Laws Camp and on to Caramba, and the Cedar Trail from Willow Creek Trail to Laws, are euphemistically (and arguably dangerously) described by the Forest Service as “not maintained”. In reality both trails have been abandoned for more than a decade and no longer exist. They are so heavily overgrown, largely with dense whitethorn which obscures dozens of downed trees, that hikers should not attempt to follow them (regardless of how much you may trust any particular app).

An informal use trail to Laws is much more direct, generally well maintained, and avoids the bushwhacking of the abandoned trails (some local Idyllwild hikers dubbed it the “King Trail” when I established the route in 2019). It leaves Willow Creek Trail exactly 1.0 mile from Saddle Junction, 0.46 mile from the Skunk Cabbage turning (trailhead at N 33.7796, W 116.6590). The route descends following former deer trails for 1.2 miles, meeting Willow Creek about 0.15 mile upstream from the site of the historic Laws Camp (the remains of which were destroyed by the 2013 Mountain Fire and subsequent flood and treefall damage). One huge pine tree fell in late 2024 across the King Trail about midway down that requires a minor scramble underneath, but nine additional blowdowns have been removed since January 2025, with the trail trimmed and cleaned three times this year.

From Laws east to Caramba the original Caramba Trail has been cairned by myself and others and can largely be followed with skilled route-finding. My most recent 2025 survey counted 120 trees down on this 2.1 miles of trail. It is extremely obscure for the first 0.5 mile east of the Willow Creek crossing, becoming more obvious (but still subtle) as it descends towards Caramba. Very cautious navigation is strongly recommended throughout the area.

Stormy weather this autumn brought down another seven trees across Spitler Peak Trail. All were removed by the Trail Report on 20th October, bringing to 169 the total number of trees we have removed from this route in the past seven years. One very large burned cedar is the only tree that remains across the trail, immediately after the first creek crossing 3.2 miles up from the trailhead.

The Zen Center Trail continues its serious deterioration that started following the 2013 Mountain Fire, with a combination of vigorous regrowth and treefall hazards further obscuring the route with each passing season. The lower and upper thirds of this trail are partially cairned and not too bad for those who are very familiar with the former route, but even the experienced find navigating the central section tricky. Long trousers, scrambling gloves, and a genuine enjoyment of bush-whacking are all strongly recommended.

Temperatures in early November have been broadly above seasonal at all elevations. They are expected to remain above average into the second week of November, before cooling from 12th. Forecasts are suggesting back-to-back minor winter storm systems on 13th-14th and 17th-19th November. The first system will be mild, with rain potentially as high as 9,000 ft (before possibly transitioning to light snow). Rain may persist at mid elevations for 1-2 days, starting on the afternoon of 13th. The system on 18th will be colder, with a dusting of snow as low as 6500 ft possible. For the first storm, snowfall is forecast to be limited to no more than 1-2 inches around the highest peaks, while estimates for the later storm have ranged widely from 1-12 inches.

Water flows have deteriorated again despite inches of rain in recent months (some example photos below). However most key hiker water sources are flowing. All ephemeral sources that dried in the summer but temporarily flowed again earlier this month are now dry again. Wellman’s Cienega and the pipe in Round Valley are flowing steadily and will now maintain useable flow into the winter. The creek in Little Round Valley has dried again both where it passes through the meadow and also where it crosses Deer Springs Trail, but continues to flow patchily in its central section. Deer Springs creek (PCT Mile 185.4) dried up in late July where it crosses the trail of the same name, and although it has intermittently flowed again twice during recent rains, is now functionally dry again. The North Fork of the San Jacinto River is flowing where it crosses both Fuller Ridge (PCT Mile 186) and Deer Springs trails, but is largely dry where it crosses Seven Pines Trail. Stone Creek has now dried again where it crosses Deer Springs Trail (near PCT Mile 183.6). Marion Creek is flowing steadily where it crosses the Suicide Rock Trail. Strawberry Cienega (approx PCT Mile 181.9), has dried again.

Willow Creek is flowing weakly again where it crosses the Willow Creek Trail, having dried in August. Hidden Lake functionally dried by the end of June. Long Valley Creek is dry where it passes through Round Valley, as is the nearby creek in Tamarack Valley. Water is flowing reliably in Tahquitz Creek at PCT Mile 177 and again further downstream at the north end of Little Tahquitz Meadow (although it is dry between those two locations)(photos below). The pipe in Tahquitz Meadow dried in mid July. Skunk Cabbage Meadow creek is functionally dry. Middle Spring on Devil’s Slide Trail has been functionally dry since 1st August, but I maintain a tiny pool there from which dogs can drink.

During the federal government shutdown, the Forest Service Idyllwild Ranger Station is closed. Unlike the 2018-19 shutdown which occurred in the winter months of December-January, gates on Forest Service roads and USFS campgrounds have remained open (for now).

Be bear aware. Although generally rarely reported, at least six individually identifiable Black Bears have been observed in the San Jacinto mountains since 2017 (I have personally encountered at least one annually for the past seven years). A full-sized adult bear with a right ear tag has been seen in multiple locations from Willow Creek to Fern Valley since August (see my video from a trail cam on 14th September available here, and images from Fern Valley in late August in a prior Report linked here). A smaller, second individual has been reliably reported at least twice, most recently in late September in lower Fern Valley. My brief videos from Devil’s Slide Trail in September 2021 (linked here) and one walking past our house in 2018 (linked here) show two further individuals. There have been no reports of negative interactions with humans in the high country, at or near campsites, or on trails, but bear-safe storage of food when camping is recommended.

The fire lookout at Black Mountain is closed indefinitely due to issues identified in a May 2025 safety inspection. Tahquitz Peak lookout reopened (likely only for a few weeks) on 7th November having been closed all season to date.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (more frequently during stormy weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures remain generally above seasonal throughout early November, before cooling markedly after Tuesday 11th.

Consecutive winter storm systems are forecast (with increasing reliability) for 13th-15th and 18th November. The first system will be relatively mild for the season, with a freeze level above 7000 ft and initial rainfall possibly near 10,000 ft (before turning to very light snow). Steady light rain from late on Thursday 13th into Saturday 15th could total one inch at mid elevations (e.g., Idyllwild). Only 1-3 inches of snow are currently forecast around the highest peaks, with a dusting possible at elevations as low as Pine Cove and upper Fern Valley.

The system on 18th is forecast to be colder, with a freeze level potentially dropping to 6000 ft and hence a dusting of snow as low as Idyllwild possible. Snowfall in the high country is expected to be somewhat greater with the second storm than the first, but still only 2-4 inches, falling throughout the day on Tuesday 18th.

The first (very minor) winter storm of the season impacted the region on Tuesday 14th October. Snow fell intermittently at San Jacinto Peak most of the afternoon, accumulating to about 1.5 inches. Snow dusted as low as 9000 ft, averaging about one inch above 9500 ft. Rainfall in Idyllwild (5550 ft) totaled an impressive 0.76 inch for the day, with 0.85 inch at Saddle Junction (8100 ft).

That storm was a dramatic contrast from the relatively mild, humid, weather experienced since late August. The San Jacinto mountains had a remarkable sequence of tropical and monsoonal autumnal rains spread across ten distinct rain events between 22nd August and 10th October. San Jacinto Peak recorded an impressive 8.74 inches of rainfall, with 4.58 inches recorded in Idyllwild (at 5550 ft).

One interesting consequence of the climate change crisis is the increasing prevalence of tropical, rather than monsoonal, rainfall in the San Jacinto mountains. In three of the four most recent years (2022-2025) the majority of rainfall in our region between August-October has come from tropical sources (generally from the south or south-west) as opposed to the historically much more frequent monsoonal storms (originating from easterly directions).

At San Jacinto Peak (10,811ft/3295m) on Friday 7th November 2025 at 0945 the air temperature was 46.1°F (8°C), with a windchill temperature of 39.6°F (4°C), 35% relative humidity, and a cool NNE wind sustained at 6 mph gusting to 9.7 mph.

At the Peak on Monday 3rd November 2025 at 0840 the air temperature was 44.1°F (7°C), with a windchill temperature of 36.5°F (2°C), 16% relative humidity, and a remarkably steady SW wind sustained at 9 mph gusting to 10.9 mph.

At the Peak on Friday 31st October 2025 at 0910 the air temperature was 45.3°F (7°C), with a “windchill” temperature of 43.0°F (6°C), 36% relative humidity, and a very light NNE breeze sustained at 0 mph gusting to 3.0 mph.

At the Peak on Wednesday 29th October 2025 at 0945 the air temperature was 56.2°F (13°C), with a “windchill” temperature of 50.7°F (10°C), 30% relative humidity, and a barely discernable NW breeze sustained at 0 mph gusting to 2.2 mph.

TRAIL CONDITIONS

Trails have cleared of the icy snow that fell three weeks ago. Thankfully most trails suffered relatively minor tread erosion from intense rains in August-October. Neither the Wolf Fire in late June nor the Rosa Fire in early August had major impacts on the trail system, although the latter did burn the southernmost 0.5 mile of the Palm Canyon trail.

For the first time in nearly a decade, Deer Springs Trail from its trailhead to Little Round Valley is now completely clear of blowdowns, with 26 trees removed since the middle of last year (of which 70% were cut by the Trail Report). A joint Eastern Sierra Conservation Corps/State Park crew working in early October trimmed encroaching vegetation along Deer Springs Trail just above the Fuller Ridge Trail junction to about 9300 ft.

On PCT Miles 170-175 (roughly Apache Peak to Red Tahquitz) most blowdowns have been removed but six trees remain to be cut around South Peak (Miles 173.5-174) of which most are significant obstructions for hikers. Sections of the trail are badly overgrown with brush and in their worst condition in decades, especially most of Miles 168-174.

The two large downed trees near PCT Mile 180 were removed by the Trail Report this spring. The Strawberry Trail (PCT Miles 180.8-183.1) has had long-term blowdowns removed this month by Forest Service volunteers. The brush along Miles 181-181.7 has become heavily overgrown since it was last trimmed by the Trail Report in 2021, but there is a plan for trimming work in the next few months.

The maintenance condition of the Fuller Ridge (Miles 185.5-190.5) section of the PCT improved significantly in July 2025, with the Trail Report clearing most of the 15 blowdowns and a PCTA volunteer crew cutting the remainder the following week.

On the Wellman Trail, Wellman’s Cienega is flowing well compared to earlier in the autumn (photo below). The Trail Report continues the work it started last year to keep this trail well-maintained (after it had become badly overgrown by early 2024).

Dark Canyon Road (4S02) had some effective basic maintenance on its dirt section in the spring. The associated Dark Canyon campground is closed for the year (apparently due to federal budget cuts).

For the first time in about 20 years Seven Pines Trail has a continuous route completely cleared of blowdown trees, with the trail also as faithful to the original route as possible. The Trail Report “adopted” Seven Pines as a priority for maintenance work nearly a decade ago due to a disproportionate number of lost hiker rescues (with State Park and Forest Service evidently no longer maintaining the route). Since 2019 we have now removed exactly 100 downed trees – including 25 since April of this year – and the trail is largely trimmed and cleared semi-annually. Although our work has restored this delightful trail, Seven Pines remains a genuine wilderness trail unlike the wider, bare, obvious routes of, for example, Devil’s Slide or Marion Mountain trails. Cautious navigation remains invaluable for those without extensive experience of hiking this trail.

Black Mountain Road is open and in its typical non-graded condition, i.e. lumpy but readily passable in any moderate clearance vehicle. The tap at Cinco Poses Spring currently has reliable water (located alongside the road 0.2 mile below the Boulder Basin turning).

On Willow Creek Trail whitethorn urgently needs trimming again especially near the boundary between the two agencies. The two large trees remaining uncut in the State Park section from several years ago have easy workarounds.

The Caramba Trail from near Reeds Meadow through Laws Camp and on to Caramba, and the Cedar Trail from Willow Creek Trail to Laws, are euphemistically (and arguably dangerously) described by the Forest Service as “not maintained”. In reality both trails have been abandoned for more than a decade and no longer exist. They are so heavily overgrown, largely with dense whitethorn which obscures dozens of downed trees, that hikers should not attempt to follow them (regardless of how much you may trust any particular app).

An informal use trail to Laws is much more direct, generally well maintained, and avoids the bushwhacking of the abandoned trails (some local Idyllwild hikers dubbed it the “King Trail” when I established the route in 2019). It leaves Willow Creek Trail exactly 1.0 mile from Saddle Junction, 0.46 mile from the Skunk Cabbage turning (trailhead at N 33.7796, W 116.6590). The route descends following former deer trails for 1.2 miles, meeting Willow Creek about 0.15 mile upstream from the site of the historic Laws Camp (the remains of which were destroyed by the 2013 Mountain Fire and subsequent flood and treefall damage). One huge pine tree fell in late 2024 across the King Trail about midway down that requires a minor scramble underneath, but nine additional blowdowns have been removed since January 2025, with the trail trimmed and cleaned three times this year.

From Laws east to Caramba the original Caramba Trail has been cairned by myself and others and can largely be followed with skilled route-finding. My most recent 2025 survey counted 120 trees down on this 2.1 miles of trail. It is extremely obscure for the first 0.5 mile east of the Willow Creek crossing, becoming more obvious (but still subtle) as it descends towards Caramba. Very cautious navigation is strongly recommended throughout the area.

Stormy weather this autumn brought down another seven trees across Spitler Peak Trail. All were removed by the Trail Report on 20th October, bringing to 169 the total number of trees we have removed from this route in the past seven years. One very large burned cedar is the only tree that remains across the trail, immediately after the first creek crossing 3.2 miles up from the trailhead.

The Zen Center Trail continues its serious deterioration that started following the 2013 Mountain Fire, with a combination of vigorous regrowth and treefall hazards further obscuring the route with each passing season. The lower and upper thirds of this trail are partially cairned and not too bad for those who are very familiar with the former route, but even the experienced find navigating the central section tricky. Long trousers, scrambling gloves, and a genuine enjoyment of bush-whacking are all strongly recommended.

The first winter storm of the season impacted the region on Tuesday 14th October, with precipitation starting about 1130 and lasting until near dusk. Snow fell intermittently at San Jacinto Peak most of the afternoon, accumulating to about 1.5 inches, but with a periodic mix of drizzle and sleet, and finishing with a thick icy coating from late freezing rain. Snow dusted as low as 9000 ft, averaging about one inch above 9500 ft. Rainfall in Idyllwild (5550 ft) totaled an impressive 0.76 inch for the day, with 0.85 inch at Saddle Junction (8100 ft). I posted a short video report from San Jacinto Peak early on 15th, linked here. Despite a steady warming trend in recent days, on Wednesday 22nd thin icy snow still persisted in patches in the most shaded areas above 9900 ft elevation, although spikes are no longer required anywhere.

This storm was a dramatic contrast from the relatively mild, humid, weather we have generally experienced since late August. The San Jacinto mountains had a remarkable sequence of tropical and monsoonal autumnal rains in the past eight weeks. San Jacinto Peak recorded an impressive 8.74 inches of rainfall spread across ten distinct rain events between 22nd August and 10th October, with 4.58 inches recorded in Idyllwild (at 5550 ft) over the same period.

The most recent tropical rains, on 9th-10th October, were concentrated on the western flank of the mountain range. The junction of Marion Mountain and Deer Springs trails at 8600 ft recorded 2.23 inches of rain, with 1.67 inches at 9800 ft in Little Round Valley, in contrast to just 0.36 inch at Saddle Junction (located on the southern flank of the high country).

Water flows have improved following the rain events of recent weeks, although many rapidly returned to their mid-August condition (see photos below). Some key hiker water sources are flowing reasonably well. All ephemeral sources dried in the summer but some are temporarily flowing again, especially those on the western side of the mountains. Wellman’s Cienega and the pipe in Round Valley are flowing and should now maintain useable flow into the winter. The creek in Little Round Valley has already dried again both where it passes through the meadow and also where it crosses Deer Springs Trail, but continues to flow patchily in its central section. Deer Springs creek dried up in late July where it crosses the trail of the same name, and although it has intermittently flowed again twice during recent rains, it will dry again soon. The North Fork of the San Jacinto River is flowing where it crosses both Fuller Ridge and Deer Springs trails. Stone Creek is temporarily trickling again where it crosses Deer Springs Trail (near PCT Mile 183.6). Marion Creek is flowing steadily where it crosses the Suicide Rock Trail. Strawberry Cienega (approx PCT Mile 181.9), which dried in midsummer, is temporarily trickling again, but not sufficiently to filter any useful volume of water.

Willow Creek is flowing again where it crosses the Willow Creek Trail, having dried in August. Hidden Lake dried by the end of June (although it temporarily holds a tiny pond from recent rains). Long Valley Creek is dry where it passes through Round Valley, as is the nearby creek in Tamarack Valley. Water is flowing reliably in Tahquitz Creek at PCT Mile 177 and again further downstream at the north end of Little Tahquitz Meadow (although it is dry between those two locations). The pipe in Tahquitz Meadow dried up in mid July. Skunk Cabbage Meadow creek is functionally dry and no longer useful for filtering. Middle Spring on Devil’s Slide Trail has been functionally dry since 1st August, but I maintain a tiny pool there from which dogs can drink.

During the federal government shutdown, the Forest Service Idyllwild Ranger Station is closed. Unlike the 2018-19 shutdown which occurred in the winter months of December-January, gates on Forest Service roads and USFS campgrounds have remained open (for now).

Fire lookouts at Black Mountain and Tahquitz Peak are closed indefinitely due to issues identified in a May 2025 safety inspection at Black Mountain. Neither tower is now expected to reopen until 2026.

Be bear aware. Although generally rarely reported, up to six individually identifiable Black Bears have been observed in the San Jacinto mountains since 2017, and I have personally seen at least one annually for the past seven years. A full-sized adult bear with an ear tag has been seen in multiple locations from Laws to Fern Valley since late August (see my video from 14th September available here, and images from late August in a prior Report linked here). My other brief videos from Devil’s Slide Trail in September 2021 (linked here) and one walking through our property in Idyllwild in 2018 (linked here) show two other individuals. There have been no reports of negative interactions with humans in the high country, at or near campsites, or on trails.

Daily survey hikes by the Trail Report year-round in the San Jacinto mountains include multiple routes to the highest peaks including San Jacinto Peak typically at least twice per week (more frequently during stormy weather), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER

Temperatures plunged to well below seasonal for October on 13th-16th with the passage of a cold front associated with the first winter storm of the season on Tuesday 14th. Strong winds associated with passage of the cold front briefly dropped windchill temperatures close to 0°F (-18°C) at the highest peaks.

Temperatures warm quickly this week, especially at mid elevations, and will be above seasonal for late October on most days from 18th to the end of the month. The last few days of October are forecast to be unusually warm for the season.

The San Jacinto mountains received valuable monsoonal and tropical rainfall in ten distinct events since late August, as described in more detail in the previous Report and links therein (linked here). The most recent tropical rains, on 9th-10th October, were associated with the breakdown of former Hurricane Priscilla far to our south. Locations on the western side of the high country received the bulk of the the intense rainfall, with 2.23 inches of rain recorded at the junction of Marion Mountain and Deer Springs trails at 8600 ft, and 1.67 inches at 9800 ft in Little Round Valley. In contrast, locations to the south of the high country received much less rain, with Saddle Junction recording just 0.36 inch, and Idyllwild 0.49 inch, while higher elevation locations on the east side fell between those extremes (1.21 inches at Wellman’s Cienega). San Jacinto Peak recorded 1.43 inches.

One interesting consequence of the climate change crisis is the increasing prevalence of tropical, rather than monsoonal, rainfall in the San Jacinto mountains. In three of the four most recent years (2022-2025) the majority of rainfall in our region between August-October has come from tropical sources (generally from the south or south-west) as opposed to the historically much more frequent monsoonal storms (originating from easterly directions).

At San Jacinto Peak (10,811ft/3295m) on Wednesday 22nd October 2025 at 0930 the air temperature was 37.8°F (3°C), with a windchill temperature of 21.9°F (-6°C), 46% relative humidity, and a chilly SW wind sustained at 12 mph gusting to 21.4 mph.

At the Peak on Friday 17th October 2025 at 0940 the air temperature was 31.7°F (0°C), with a windchill temperature of 17.6°F (-8°C), 47% relative humidity, and a cool NNE wind sustained at 8 mph gusting to 14.9 mph.

At the Peak on Wednesday 15th October 2025 at 0645 the air temperature was 22.5°F (-5°C), with a windchill temperature of 5.5°F (-15°C), 100% relative humidity, and a frigid due West wind sustained at 14 mph gusting to 22.0 mph.

At the Peak on Tuesday 14th October 2025 at 1045 the air temperature was 30.3°F (-1°C), with a windchill temperature of 14.0°F (-10°C), 93% relative humidity, and a bitter SW wind sustained at 10 mph gusting to 20.6 mph.

TRAIL CONDITIONS

Icy snow was almost continuous on trails above 9300 ft on 15th October, with a patchy mix of ice, snow, and sleet down to 8800 ft. Spikes were useful, but not essential for those very familiar with hiking in such conditions, above about 9500 ft. These conditions will improve steadily with a warming trend over 16th-19th October, with melting most rapid at lower elevations (initially below 10,000 ft) and on the most sun-exposed trails. As of Friday 17th, very thin icy snow was still widespread in the sheltered sections of the Peak Trail above 9900 ft, and as low as 9300 ft on the least sun-exposed sections of Deer Springs Trail. With caution, spikes are generally not required, although there is little harm with carrying them of course.

Thankfully most trails have suffered relatively minor tread erosion from recent intense rains. Neither the Wolf Fire in late June nor the Rosa Fire in early August had major impacts on the trail system, although the latter did burn the southernmost 0.5 mile of the Palm Canyon trail.

For the first time in nearly a decade, Deer Springs Trail from its trailhead to Little Round Valley is now completely clear of blowdowns, with 26 trees removed since the middle of last year, of which 70% were cut by the Trail Report. A joint Eastern Sierra Conservation Corps/State Park crew working in early October made good progress trimming encroaching vegetation along Deer Springs Trail just above the Fuller Ridge Trail junction to about 9300 ft.

On PCT Miles 170-175 (roughly Apache Peak to Red Tahquitz) most blowdowns have been removed but six trees remain to be cut around South Peak (Miles 173.5-174) of which most are significant obstructions for hikers. Sections of the trail are badly overgrown with brush and in their worst condition in decades, especially most of Miles 168-174.

The two large downed trees near PCT Mile 180 were removed by the Trail Report this spring. The Strawberry Trail (PCT Miles 180.8-183.1) has had several of its decade-old blowdowns removed this month by Forest Service volunteers. The brush along Miles 181-181.7 has become heavily overgrown since it was last trimmed by the Trail Report in 2021, but there is a plan for trimming work in the next few months.
