Conditions summary as of October 17, 2026
A cold front brings rain turning to snow and possible brief freezing rain overnight into Saturday, with strong winds, upslope snow, and freezing temperatures reaching down to the trailheads by late morning. Trails will be wet, slick, and icing over, with wind chill well below freezing near the summit. Postpone Saturday; Sunday looks calmer, though trails will remain icy, snow-packed, and wet.
Expect a sharp temperature drop with height: milder at the trailhead, then near or below freezing from treeline up, with winds strengthening above about 4,000 ft and wind chill in the teens at the summit. Carry the full winter layering system from the start; the freezing-level transition near 4,000 ft is the key point where wet trail turns icy and a shell and insulation are needed immediately.
Best Hiking Window
Sunday late morning through early afternoon, after skies begin to clear and temperatures rise above freezing; avoid Friday night and Saturday entirely

“Happy October! It's a new month which means grid support has begun. This was one of Luke's 3 hikes needed to grid out the month so we got started right away. The trail was wet right out of the gate. All the rocks were wet and the mud was ample. Much of it for the first 2 miles is kind of avoidable but watch your step. The steeper sections of the North Twin trail up to the north peak were wet as well and there were wet leaves on wet rocks to contend with. We just watched our footing and were fine. The views off the back of North Twin were lovely and necessitated a nice long snack break. The mud between the 2 peaks is it's usual typical squelchy self. With some creativity you can kind of stay dry and clean. I still managed to mistake grey mud for a rock and dunked a foot. The south peak was lovely and breezy so we hung out for awhile to soak it all in. It was great to see Danielle and her crew out and about coming from Guyot tentsite. We had a most excellent day laughing and engaging in ridiculous antics as usual. SO SO SO happy for today!”

“37 @ the start, clear skies, beautiful morning. Fast flat 1st 1.9 miles mostly dry trail. River flowing but low, no issues crossing. Wet early in all the usual spots, gentle start, trail in great shape. It’s been awhile since I’ve gone this way and not as steep early as I remembered. It does get steep & never ending before it finally flattens out. Bright blue skis, views were incredible. Quite a few on North including two who finished their 48! Mud starts almost immediately on the Spur and continues most of the way to South. Several really unavoidable spots but rocks helped if you have long legs. Little more breezy on South but beautiful nonetheless. Lots of people on the way back to North. Hung out for a bit on the rocks enjoying some different views into both Maine & Vermont. Fast down no issues, several groups heading up. Perfect weather for my last hike of summer.”
