Conditions summary as of October 17, 2026

Saturday brings freezing drizzle, a fresh dusting of snow, and subfreezing temperatures from trailhead to summit, with trails glazed in ice and gusts to 40 mph on the summit and higher gusts possible on open ledges. Wind chill near 0°F and short October daylight add real hypothermia and slip risk. Sunday is a much better option as high pressure builds, winds ease, and skies begin to clear.

Freezing level runs from roughly 600 ft to 3,500 ft, so the whole trail is subfreezing, from around 27-39°F at the trailhead to 19-31°F near the summit with wind chill falling from about 13°F to -3°F. Start with a moderate layer system and add insulation and wind protection before leaving treeline cover, and expect traction to be needed from the trailhead onward.

Best Hiking Window

Sunday late morning through early afternoon, when winds drop, skies break up, and temperatures climb toward the mid-30s. On Saturday, only experienced, well-equipped hikers should attempt it after the freezing drizzle ends and with a very early start for the short daylight.

Hazards
Verglas and icy rock slabs from freezing drizzle and overnight rain-to-snow transition
Slick, snow-dusted leaf litter hiding wet rock and roots
Wind chill near 0°F at the summit and frostbite risk on exposed skin
Strong NW winds with gusts to 40 mph, with stronger gusts on open ledges and the Webster Cliff Trail
Limited visibility in cloud and upslope snow showers
Rime ice and snow load on branches coming down in gusts
Only about 11 hours of daylight, with early-season hypothermia risk if wet or delayed
Icing on stream crossings and wet slabs after a wet 48 hours (0.62 in total precipitation)
Recommended Gear
Microspikes or other traction devices
Insulated waterproof shell and pants
Warm hat, balaclava or buff, and insulated gloves with spares
Insulating mid-layers (fleece or puffy) kept dry in a pack
Headlamp with extra batteries
Goggles or eye protection for upslope snow and wind
Trekking poles
Insulated water bottle or hot drink, plus high-calorie snacks
Emergency bivy or space blanket

Trail: Webster Cliff Trail, Crawford Path, Eisenhower Loop, Mt. Clinton Trail, Dry River Trail, Saco River Trail

Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Mud - Minor/Avoidable, Leaves - Significant/Slippery

“A wonderful overnight backpacking trip to some southern Presidentials and the Dry River Wilderness. Webster Cliff Trail is in good shape although there are a couple wet spots. Crawford Path and Eisenhower loop were great and I’m sure there are many trail reports from the past weekend detailing those hikes. I mostly wanted to report on Mount Clinton Trail and Dry River Trail as I know those are less commonly used. The White Mountain Guide doesn’t lie— Mount Clinton Trail REALLY requires care to follow at times especially now with the fallen leaves. Do not expect blazes out on these wilderness trails. But if you seek peace and solitude at this busy time of year it can be found :) Pay attention to branches that are laid down intentionally to keep you on the trail, and when the trail seems to go into the riverbed, that is correct. You’ll see the cairns on the riverbed rocks. Dry River Trail was a fall delight and the foliage was perfect and worth the PUDs. A Mizpah Hut croo member advised us that the water crossings would be safe but the Dry River Trail may be excessively muddy, so we were pleased to find almost no muddy spots! Saco River Trail back to the junction with the AT was a blue blaze haven after getting out of the wilderness area. You’ll have no trouble following that one.”

“Big loopy loop to tag all my summit goals for the day and avoid the morning highland center - Crawford path - Pierce clusterf*ck 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”

Trail: Webster-Jackson Trail, Webster Cliff Trail, Crawford Path, Eisenhower Loop

Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Standing/Running Water on Trail, Mud - Minor/Avoidable, Mud - Significant

“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.”

    32-year-old woman from Somerville, Massachusetts

    On July 3, 2023, Brynne Quinlan slipped on a wet-rock section of the Webster Jackson Trail while descending and suffered a leg injury severe enough to prevent her from continuing on her own. She called 911, prompting a response from NH Fish and Game, Pemi Valley Search and Rescue Team, and AMC employees. Rescue personnel reached her approximately 2 miles up from the trailhead and carried her out in a litter, arriving at the trailhead at approximately 11:20 p.m.
