Conditions summary as of September 1, 2026
Mount Jackson currently has mild temperatures and light winds, but expect wet, slippery rocks and muddy stretches along the ridge from recent moisture, along with increasing fog and wind as a system approaches Wednesday. Tuesday offers the best conditions before showers and stronger winds move in overnight Wednesday into Thursday.
Expect temperatures to drop from around 57–66°F at the trailhead to 53–56°F at the summit, with wind increasing from about 9 mph to 15 mph — bring a light wind layer for the upper ridge and prepare for wetter, slicker rock near treeline and the summit.
Best Hiking Window
Tuesday morning through early afternoon offers the driest, calmest conditions before clouds thicken and winds increase Tuesday evening; avoid Wednesday and Thursday when rain and wind intensify.

Trail: Webster Jackson Trail, Webster Cliff Trail
Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Standing/Running Water on Trail, Mud - Minor/Avoidable, Mud - Significant
“Morning hike for Cody's 52WAV and 4K hikes. Lower trail was fairly dry with occasional soft mud/wet spots. But at higher elevations the trails were pretty wet. The potentially slippery wet rocks and some mud made for slower going. Multiple muddy stretches along the ridge. Slabs on the ridge and on Jackson were mostly dry. Views were OK today, some cloudy haze.”
Trail: Webster Jackson Trail, Webster Cliff Trail, Crawford Path, Eisenhower Loop, US 302
Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Standing/Running Water on Trail, Mud - Minor/Avoidable
“Hot humid day in the woods. Dry trail to start, some slippery rocks and mud in the usual spots, overall dryer than I was expecting. Only 2 on top of Jackson, I ate & enjoyed the views knowing it would be busy later on. Steep and wet rock coming down from top, fairly wet to the hut. Bog bridges are starting to show some wear, very deep mud. Refilled water for the climb to Pierce, dry to top. Absolute cluster around the summit, too many here so I found a spot to rest just past it. Still many here but a lot quieter with a nice breeze. Many folks coming from Eisenhower early, really hot for the climb. Wet muddy spots but nice to see many herd paths have been blocked, thank you! Lots of folks here but found a spot to sit with a nice breeze. Somewhat hazy views, was thinking about going down Edman's Path to avoid the crowds but opted not as the road walk sucks. Quick back too no people at junction. Very wet for most of the way down, passed many heading up. Pack plenty of water unless heading to hut as it’s very humid right now in the woods.”
Trail: Webster-Jackson Trail
Conditions: Dry Trail
“Great morning to go up and down before work. Cool temps, nice breeze up top and a dry trail for this hike make it a dream. Whoever is doing the trail work and maintenance, thank you. It is making a difference.”
