Editorial note: as expected, record heat for March has resulted in dramatic snowmelt this week. Consequently I have been updating trail conditions daily to the greatest extent possible. I have never seen snow clear as rapidly in these mountains as this past week, in any month, even May or June, let alone in mid March. The March air temperature record for San Jacinto Peak has been broken three times in the past seven days, now by an almost incomprehensible 14.1 degrees of Fahrenheit compared to the pre-2026 record. Indeed the temperature recorded on 19th March 2026 (59.6°F) exceeds the all-time record highs for April and May as well. Sadly it is an overused word, but what we are currently witnessing is genuinely unprecedented.
Intense high pressure over the region will result in exceptional heat this week. Daily and monthly temperature records are forecast to be shattered throughout Southern California. Temperatures on 17th-22nd will far exceed seasonal for March in the San Jacinto mountains, but remarkably the temperatures forecast for 19th and 20th in particular will exceed even the seasonal averages for July and August, which is beyond astonishing for mid March.
Obviously melting of what little snow remains will be dramatic, and the extent of snow remaining on high country trails will decline daily. The San Jacinto mountains may be in the unprecedented state of being largely snow-free by late March.
Carrying spikes remains useful for most trails above about 9000 ft (possibly lower in places) for at least the next week or so, because despite the weather established tracks are well consolidated by hiker traffic, especially on upper Deer Springs Trail (which is least sun-exposed in the morning, and hence somewhat firm).
Spikes are no longer required for PCT hikers who remain on the PCT, but they are recommended for thru hikers who use alternates involving San Jacinto Peak.
Snow depths are no longer given in this posting. This does not mean there is no snow in the high country, simply that snow is both generally localized to the highest elevations, and that it is rarely more than a few inches deep anywhere, especially on the established trails. As discussed elsewhere, melting – which has already been steady for the past week – will be extremely rapid over the next week, so listing nominal snow depths that will change daily serves little purpose.
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.
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
The past six weeks, in common with the past six months, have seen a roller-coaster ride of temperatures and associated weather. Three snow storms in very quick succession impacted the region across four days on 16th-19th February, as described in detail in a prior Report (linked here).
Temperatures rose dramatically 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 low pressure system on 6th-8th March, with accompanying strong winds and cold temperatures in the high country.
Temperatures rose yet again starting 11th March, briefly stabilized above seasonal on 12th-15th, and will rise even further, to near or even above midsummer averages, on 16th-22nd. A new all-time March record high for San Jacinto Peak was set last week on Friday 13th, but was shattered again on both 18th and 19th.
With such a pronounced high pressure system over Southern California, it probably goes without saying that there is no precipitation in the forecasts.
NWS/NOAA data confirm that the four month period November-February this winter was the hottest for those four months combined on record for Riverside County (131 years of data). The same period was the second hottest all-time for the entire state of California, only behind November 2014-February 2015.
At San Jacinto Peak (10,810 ft/3295 m) on Thursday 19th March 2026 at 0850 the air temperature was 59.6°F (15°C), with a “windchill” temperature of 57.4°F (14°C), 10% relative humidity, and a very light SSE wind sustained at 2 mph gusting to 4.6 mph. The air temperature again broke the all-time record high for the Peak in March, set the previous day (and indeed five days before that), now by more than 14 degrees Fahrenheit compared to the pre-2026 record (photo below).
At the Peak on Wednesday 18th March 2026 at 0900 the air temperature was 54.7°F (12°C), with a “windchill” temperature of 49.1°F (10°C), 16% relative humidity, and a steady ESE wind sustained at 7 mph gusting to 10.1 mph.
At the Peak on Friday 13th March 2026 at 0920 the air temperature was 47.3°F (8°C), with a “windchill” temperature of 40.8°F (5°C), 12% relative humidity, and a light NNW wind sustained at 6 mph gusting to 10.0 mph. This air temperature set a new all-time record high (briefly) for the Peak in March – by two degrees of Fahrenheit – a record that was shattered twice just a few days later.
TRAIL CONDITIONS
Trails above about 9700 ft remain at least 30% snow-covered, and most retain some notable snow cover above 9300 ft (west side) or 9000 ft (east side). Routes below 8600 ft are now functionally clear of snow (details for specific trails below, where known).
With temperatures forecast to remain hot (for March) over the next week, snow even at the highest elevations will not refreeze overnight, and melting will continue be fast and widespread, literally changing trail conditions daily.
Most hikers will find that carrying spikes remains useful everywhere above about 9300 ft even as snow softens and melts dramatically, as established trails are nonetheless somewhat consolidated by hiker traffic and weeks of freeze-thaw cycles. This is especially true in the early mornings, and in the least sun-exposed areas (e.g., upper Deer Springs Trail before 1100).
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 a prior Report (linked here).
Current snow cover on the PCT is minimal from Miles 151 (Highway 74) to about 175 (Red Tahquitz), largely confined to tiny patches on the east slope of Spitler Peak (Mile 168) and the northerly aspects of Apache Peak (Mile 169.5), but not posing significant hazards. Snow cover is 60% between Miles 175-177. Snow cover is very patchy and averages just 10% between Miles 177 to 178.5, then it is functionally clear to Mile 180.5, but about 80% just south of Annie’s Junction to about Mile 180.8. Miles 181-185 are functionally clear. Snow cover averages 40% from Mile 185 to 185.5, although spikes are not required on the well-traveled snow track. The Fuller Ridge Trail section (Miles 185.5 to 191.5) has cleared of snow extremely rapidly this week and now averages only 20% snow cover. Stubborn sections remain around the crossing of the North Fork of the San Jacinto River (Mile 186, photo below), and on the northerly forested slopes (notably Miles 187.5-187.8 and 188.5-189). North of Mile 189, the trail is functionally clear of snow.
Carrying spikes is no longer required for PCT hikers in the San Jacinto mountains at this time, although spikes continue to be recommended for hikers who (a) take any alternate routes off the PCT to San Jacinto Peak, and/or (b) have limited experience of hiking on patchy icy snow.
The 0.4 mile section of South Ridge Trail from Chinquapin Flat to Tahquitz Peak [surveyed 20th March] is now passable without spikes for those who are especially comfortable and experienced traversing patchy icy snow. However most hikers will prefer to use spikes (ideally with poles) as one short section remains with just a single posthole track to follow through angled icy snow (photo below).
Devil’s Slide Trail [surveyed 20th March] is clear of snow to Saddle Junction.
Wellman Trail [surveyed 18th March] is largely clear of snow averaging just 20% snow cover, most of which is in the forested 0.3 mile immediately north of Annie’s Junction. Most hikers will find spikes are not required.
The Peak Trail [surveyed 18th March] is functionally clear of snow to 9900 ft. Above 10,000 ft, snow cover averages 40%, increasing to 60% immediately around San Jacinto Peak itself. Most hiker 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.
A couple of lightly-traveled, but now unfortunately rather lumpy, posthole tracks broadly follow the East Ridge Trail route [surveyed 18th March] through 95% snow cover from near the Miller switchback (10,400 ft) to San Jacinto Peak, giving, as always, an excellent alternative to the uppermost Peak Trail.
The Round Valley Trail [surveyed 18th March] has a rapidly thinning 20% snow cover to Round Valley, and thereafter a well-traveled posthole track through 60% snow cover to Wellman Divide.
Deer Springs Trail [surveyed twice per week in March, most recently on 19th] is clear of snow to Strawberry Junction, and then functionally clear to the junction with Marion Mountain Trail. Thereafter, snow cover on the trail averages just 10% to 9300 ft, increasing to 40% from that elevation to Little Round Valley. Little Round Valley is clearing remarkably rapidly, and although average snow depth is only 3-4 inches, it is a mix of extensive cleared areas interspersed with drifts up to 10 inches deep. Above Little Round Valley snow cover averages only 30%, and the trail route is now largely visible, although some cautious navigation is required where drifts cover switchbacks. With caution, spikes are no longer required on Deer Springs Trail, although many hikers will continue to find them useful for descending parts of the upper trail.
Marion Mountain Trail [surveyed 19th March] is functionally clear of snow, with just a handful of tiny softening snow patches remaining very close to the junction with Deer Springs Trail. Spikes are not required.
Seven Pines Trail is largely clear of snow, with just 20% cover on the uppermost 0.5 mile of trail. There is a lightly traveled posthole track visible through the upper snow patches.
Strawberry Trail (PCT Miles 181-183) is now functionally clear of snow.
South Ridge Trail to Tahquitz Peak [surveyed 20th March] is clear of snow to Tahquitz Peak. Four new blowdowns that came down on this trail in the mid February storms have already been removed by the Trail Report.
Spitler Peak Trail [surveyed 15th March] was sadly decimated by blowdowns in the strong winds that accompanied the last storm in mid February. About 55 new trees came down across the trail, and it will take many weeks, weather dependent, to get the trail largely cleared (this trail has been seemingly unmaintained by the Forest Service since 2018). The Trail Report has already removed 19 trees since late February, the trail is clear as far as the main creek crossing 3.2 miles up from the trailhead, and work has begun further up (photos below; bringing to 193 the number of trees we have removed from this trail in recent years). Five large burned cedars and roughly 30 jumbles of fire-killed oak limbs remain seriously obstructing the trail in the 1.6 miles between that main creek crossing and the PCT.

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.
