The past week has seen high pressure over the region and markedly mild temperatures for November, especially at the highest elevations, where a new record high temperature for the month (55.4°F/13°C) was recorded at San Jacinto Peak on 9th.
The first jet stream-driven storm(s) of the season are now forecast starting later this week. Highly changeable, colder, and at times wintry, weather is now expected for 13th-21st November, with precipitation possible on any of those days, as multiple consecutive storm systems may impact Southern California.
Rain at mid elevations is tentatively forecast for 13th-14th, 16th-17th, and 19th-21st November, with at least 0.5 inch possible during each of those three precipitation events. One or more of these storm events may be colder than those earlier this winter, so snow levels may be lower, possibly as low as 7000 ft, although at this time forecasts are for only 1-3 inches of snow during each of the three storms even at elevations >10,000 ft.
With high pressure dominant since the storm on 1st November, temperatures rose steadily and hence snow melt was rapid. By Friday 6th November, trails were clear of snow, with only a few minor persistent sections remaining on the East Ridge Trail (further details in Trail Conditions below). Further light snowfall forecast for 13th-14th will likely change recommendations regarding traction devices.
Forest Service campgrounds at Boulder Basin, Marion Mountain and Fern Basin are now closed for the season. The State Park campground at Stone Creek is also now closed for the winter.
Following superficial grading late last year, Black Mountain Road (4S01) is in slightly better condition than in 2025, but remains far rougher than in June 2020, the last time it was comprehensively graded. Dark Canyon campground did not reopen in 2026 due to staffing/budget issues, although Dark Canyon Road (the access to Seven Pines trailhead) has remained open all year. South Ridge Road is in poor condition (although not as bad as 2019) and generally requires a high clearance and/or AWD/4WD vehicle to reach the South Ridge trailhead at the top of the road.
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 and following storm conditions), Tahquitz Peak and area at least once per week, plus a wide variety of other trails on intervening days.

WEATHER
The third snow-producing storm of this winter season impacted the San Jacinto mountains late on Saturday 31st October, with light rain and drizzle continuing into Sunday 1st November. With a warm subtropical air mass driving the storm, the freeze level was predictably high, snow dusting only down to 9650 ft, with two inches above 10,000 ft and 2.5 inches at San Jacinto Peak falling late on 31st. By the morning of 1st November, it was already drizzling as high as San Jacinto Peak, and large sections of the Peak Trail were already more slush than snow.
Mid elevations throughout the San Jacinto mountains received at least half-an-inch of rain, with many closer to one inch. The most rain recorded locally was 1.46 inches at Vista Grande (4700 ft, NWS data), with 1.22 inches at Wellman’s Cienega (9300 ft) and 0.76 inch in Idyllwild (at 5550 ft).
With an additional 2.5 inches of snow at San Jacinto Peak on 31st, the Peak received a total of 4.25 inches of snow in October 2026, the most in the month of October for at least the past decade (the previous high was 1.5 inches in October 2025).
As described above, following ten days of high pressure and mild temperatures for November, much more variable weather is forecast for 13th-21st November (at least). Rain at mid elevations is tentatively forecast for 13th-14th, 16th-17th, and 19th-21st November, with at least 0.5 inch possible during each of the three precipitation events. Snow levels may be lower than during prior storms so far this winter, possibly as low as 7000 ft, although at this time forecasts are for only 1-3 inches of snow during each storm event even around the highest peaks.
At San Jacinto Peak (10,809 ft/3295 m) on Tuesday 10th November 2026 at 0740 the air temperature was 46.4°F (8°C), with a windchill temperature of 34.5°F (1°C), 23% relative humidity, and a light NNW wind sustained at 6 mph gusting to 10.9 mph.
At the Peak on Monday 9th November 2026 at 1430 the air temperature was 55.4°F (13°C), with a “windchill” temperature of 51.4°F (11°C), 38% relative humidity, and an intermittent SW breeze sustained at 0 mph gusting to 3.9 mph. The air temperature of 55.4°F (13°C) is the all-time record highest observed at the Peak in November.
At the Peak on Friday 6th November 2026 at 0820 the air temperature was 34.4°F (1°C), with a windchill temperature of 18.7°F (-8°C), 26% relative humidity, and a frigid NNE wind sustained at 11 mph gusting to 23.3 mph.
TRAIL CONDITIONS
Trails cleared by 3rd November of the light snowfall that had accumulated on 31st October. Only the lightly traveled East Ridge route to San Jacinto Peak still retained 30% snow cover on 10th November. On the trail system, traction devices are not required at this time (although this advice may well change by Saturday 14th).
Hikers exploring off-trail among the 10,000+ ft peaks should note that significant, thin, icy snow cover remains on sheltered and north-facing slopes around Jean and Shirley peaks, and Marion Mountain, at this time, for which some hikers may find spikes useful.
Established springs and pipes are flowing steadily at this time, and hence flow rates and water availability are not expected to be discussed further this winter. Note that most ephemeral sources currently remain dry however.
Significant sections of the Pacific Crest Trail in the San Jacinto mountains, although largely clear of blowdowns, remain in urgent need of brushing despite repeated reporting to USFS and PCTA. This includes Miles 155-157, 169-170 (Apache Peak area), 171-173, 179-183 (Saddle Junction to Strawberry Junction), and 185.5-190 (Fuller Ridge).
The first comprehensive trail trimming in decades is being undertaken by the Trail Report this year on the upper Peak Trail. My work started in late May, and the entire 0.5 mile section of trail between 10,000 ft and the Miller Peak switchback had been widened to 3-4 feet by early November. Unmanaged chinquapin overgrowth had narrowed the trail to just 10-15 inches wide in many places, which was problematic year-round, but especially in winter conditions and for pole users (example before-and-after photos in several prior reports since June).
Trail maintenance work by USFS and State Park volunteers earlier this year cleared Willow Creek Trail of blowdowns from last winter. Brush trimming work was undertaken on both the USFS and State Park sections of the trail in late July, although it was much more limited on the State Park section, and the upper switchbacks closer to Hidden Divide remain overgrown in places.
Deer Springs Trail from the trailhead to Little Round Valley was cleared of the handful of blowdowns from last winter by the Trail Report.
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 perhaps 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 several hundred 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 is marked with cairns (and subtle flagging to aid USFS work crews) and 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). Blowdowns from this winter have already been removed by the Trail Report, and the huge pine tree that fell in late 2024 was kindly removed by Forest Service volunteers in May 2026.
East from Laws the old Caramba Trail is initially heavily obscured by blowdowns and thick regrowth, but the easternmost 1.5 miles closest to Caramba camp is often well marked with cairns placed by myself and others. Much of the old trail rock work is visible in places. The first mile east of Laws is currently marked largely along the former trail route with orange flagging (for use by USFS work crews), although it is not recommended to follow this in some areas as it goes directly through blowdowns and obstructive vegetation, not around them.
Work to rehabilitate the original Caramba Trail started in June this year – combining the Trail Report, other volunteers, and Forest Service employees – almost exactly 13 years after it burned in the Mountain Fire. Unsurprisingly it is proving to be a painfully slow process and it is now certain that at least two years of work will be required to rehabilitate the old trail routes. Please do not remove, move, or (as described above) attempt to follow, flagging in this area which has been placed to guide USFS and volunteer work crews.
The Trail Report “adopted” Seven Pines Trail as a priority for maintenance work due to a disproportionate number of lost hiker rescues (with the agencies evidently no longer maintaining the route). In the past seven years we have removed 101 downed trees and the trail is largely trimmed and cleared annually. Thankfully only two large blowdowns affected the trail this past winter, and both now have very easy workarounds. Although our work has restored this delightful trail to its best condition in decades, Seven Pines remains a genuine wilderness trail very 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.

The San Jacinto Trail Report celebrates ten years of operation in 2026. The Report has helped tens of 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%, with an additional benefit of saving Riverside County 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 very much for your support.
