Conditions summary as of August 29, 2026
Late August conditions on Mount Passaconaway are favorable with dry-to-mostly-dry trails per recent trip reports, mild temperatures, and no precipitation in the last 24 hours. Winds are breezy but manageable, and this peak has no above-treeline exposure, so weather impacts are limited. Saturday looks like the better day with clearer skies and lighter winds compared to Friday evening's lingering front.
Expect temperatures to drop roughly 4°F per 1,000 feet gained, with trailhead conditions in the upper 50s to low 70s cooling to mid-to-upper 50s at the summit; winds also increase notably from around 22mph at the trailhead to near 28mph at treeline and summit, so a windproof layer is advisable as you approach the top.
Best Hiking Window
Saturday morning through early afternoon offers the most stable weather with sunshine and lighter winds before afternoon clouds increase

Trail: Pine Bend Brook Trail, Mt. Tripyramid Trail, Kate Sleeper Trail, bushwhack, Rollins Trail, Dicey's Mill Trail, Walden Trail, Square Ledge Trail, Passaconaway Cutoff, Oliverian Brook Trail
Conditions: Dry Trail, Wet Trail
“Scott needed the Tripyramids to grid out August. I needed Passaconaway and Whiteface. So why not do them together!? Overall a delightful day since we were able to car spot. The less traveled trails (south Tri to Whiteface, Passaconaway Cutoff, Oliverian Brook) are in very good shape with some stretches having a great sponginess to them that was a nice break from more northern roots and rocks. The only bad thing was a fun hiker who said my blue and yellow get up made me look like "Sunshine and Sky", which my knucklehead younger brother decided would be my new name. So that's just great. Do this hike with a friend. Spot a car. It's a big day but totally worth it.”
Trail: Blueberry Ledge Trail, Rollins Trail, Dicey's Mill Trail
Conditions: Dry Trail, Wet Trail, Mud - Minor/Avoidable
“What a great day for these two. The trails are mostly dry with a few wet areas. The muddy spots were far and few between and the mud is mostly supportive. The ledges were nice and dry so no AARP gymnastics were required. Rollins trail is just so pleasant as it meanders between the 2 peaks with great footing. Dicey's Mill has incredible footing that allows for a fast descent. It was great to bump into gridiot friends and catch up a bit on trail. So many happy and friendly hikers out today and it was so nice to get to talk to so many and hear about their various projects. Huge kudos to the Dad and his son that I talked with on the summit of Passaconaway who are going to look into winter hiking this year. :)”
Trail: Downes Brook Trail, Kate Sleeper Trail, Rollins Trail, Dicey’s Mill Trail, Square Ledge Trail, Passaconaway Cutoff, Oliverian Brook Trail
Conditions: Dry Trail
“A great day doing the loop with a road walk in the morning. We had a bit of trouble keeping the trail after we crossed Downes Brook for the fifth time and BEFORE the next crossing back over. There was a tributary stream that was running pretty strong, and that may have obscured the intended trail. We cross-crossed the river a few times to figure out where the trail continued. Ultimately it stayed on the west side of the river just a little further, but the trail was obscure in here, probably due to water washing it out. If we’d just stuck with it for a bit we would have figured it out pretty easily.”
