Conditions summary as of October 7, 2026
Cold, clear conditions on Wednesday with a forested, sheltered summit, but early-morning frost and icy patches are likely before temperatures rise. Winds build later in the day as a tightening pressure gradient returns, and a warm front brings clouds and rain by Wednesday night into Thursday. Plan for a morning start, a sunrise-to-early-afternoon window, and about 11.5 hours of daylight.
Expect trailhead temperatures near 37-57F rising to only 35-49F at the summit, with winds increasing from about 12 mph to 30 mph; wind chill drops from about 29F to 21F. The freezing level is near the lower end of the range in the early morning, so start with warm layers and expect icy surfaces higher up, then shed layers as the day warms.
Best Hiking Window
Wednesday from shortly after sunrise (around 6:49 AM) through early afternoon, finishing before winds build and clouds thicken. Avoid Wednesday night into Thursday due to rain and fog.

“Big loopy loop to tag all my summit goals for the day and avoid the morning highland center - Crawford path - Pierce clusterfuck disaster of tourists. Started up Edmands at 10am and the southerns were pretty dry except for many puddles and muddy leafy messiness on the flats. Summit of Washington was a total zoo and significantly calmer once I left Tucks and crossed Boott Spur. Medium muddy and swampy on Davis path, only wipeout of the day was me falling on my ass 50' down off the summit of Iso. From Iso express, about 10 paces north, there is an obvious faint line (old trail corridor, animal highway or local knowledge?!) that is really rough for the top 50 yards then lovely woods down until another rough bottom 50 yards to cross the stream and hit Iso west as the base of where it does the obnoxious zig outta the drainage to climb up to North Iso. Much drier until crossing Dry river and from the bottom of the cutoff up past the hut, over Jackson and down to the branch junction was a muddy, swampy wet mess. Headlamp on a mile below the hut and it was a very peaceful night. The bottom stretch down and out was pretty dry and uneventful. 20 miles and 7 summits”

“Beautiful views! Lots of yellow in Dry River watershed. More reds north and west of the Presidentials. Many people out today, as expected , but generally good trail etiquette so no major holdups and ascenders were generally allowed right of way by almost all. A few signs of people going off trail in the Alpine Zone, but no where near as extensive as I saw in northern Presidentials last week. I went down Eisenhower loop north of the summit and then back on Crawford Path; no crowds and the expansive view over Dry River watershed made for a great lunch spot.”

“I knew it was going to be a delightfully windy day which was exactly what I hoped for. I could hear that wind moving as I headed up Crawford Path closer to Pierce. The trail was pretty wet with many areas of standing and running water and squelchy mud. The rocks were all wet but were pretty grippy overall. I headed to Eisenhower first and initially it was in the clouds but as I got closer the clouds lifted and I got all the views. The winds ramped up nicely as I headed up the summit cone which made for some interesting hair in my selfies. I had a quick snack and was off to mountain #2. Things out in the open were drying off nicely but any portions of the trail that was more sheltered were still wet. The trek up Pierce was dry which was nice. The backside of Pierce down to the hut alternated between wet and dry trail so some care was needed given the steepness. From the hut to Jackson was mostly wet with some definite muddy sections but that is one of my favorite sections and I only saw a handful of people. Jackson was windy and above treeline was dry but once I descended the slabs everything was wet and muddy. Just use care in this section and you will be fine. This was an incredible day. Like make me speechless kind of day. It was nice to see the Teal Goat in the parking lot and to be able to chat for a few. This gridded out Pierce for G2. Still lots more work to be done though.”
