Conditions summary as of October 17, 2026
A passing cold front brings rain turning to snow with a possible brief glaze of freezing rain overnight, followed by strong winds and upslope snow showers on Saturday. Regional data shows near-hurricane-force gusts on higher summits, with subfreezing temperatures and icy trails extending down toward trailheads by late morning Saturday. Sunday offers much calmer, clearer conditions and is the far better choice for this hike.
Temperatures drop roughly 1.8°F per 1,000 ft, and the freezing line falls from about 4,000 ft down to the trailheads by late morning Saturday, so expect wet trail turning icy from the bottom up. Wind chill is much colder on the upper ridge (around 18°F or lower) than at the trailhead (around 30°F), so carry a warm layer system and add insulation and a shell before leaving the sheltered lower forest.
Best Hiking Window
Avoid Saturday entirely. If you must hike within the next 48 hours, wait for Sunday: start early after the morning cold, when winds ease, skies begin to clear and temperatures rise above freezing. Expect lingering ice and fresh snow on the trail, and finish well before sunset.

“I was part of a Flags on the 48 hike for Field. Our group was large so we broke up into smaller crews. Our crew opted to ascend Willey first and then make our way to Field. Kedron Flume trail is so lovely. The footing is excellent. It gets steep fast but we really liked the trail and the crew was so much fun that the time flew by. We made it to Willey and took a few quick pictures and headed to Field. The stretch between Willey and Field as some muddy sections and is tight in places but is just so pretty. We made it to Field with our flag sections just in time and our flag was flying at 11:59am. Jo-Ann sang the National Anthem and many words and stories were shared. It was a very moving experience. We visited with all the folks hiking past and then at 2pm, broke down the flag and broke up into groups again. Some headed straight down but our smaller crew headed to Tom. The footing between Field and Tom is amazing and made for very fast travel. The Mt Tom spur is in great shape and we tagged the peak and headed down. The A-Z trail down from Mt. Tom also has really good footing and the Avalon trail is positively cruisy from there. This was an absolutely incredible day with wonderful and kind people. Flags on the 48 is such a meaningful way to commemorate the events of 9/11. Huge thanks to Jo-Ann and George for all the planning and organization that went into the day. See you again next year. We all agreed that they are stuck with us.”

“Was very pleasantly surprised by the AZ trail, very beautiful upper half.Despite the 16.5 miles, it didn't feel like that much with all the lovely flat sections. I'd do this one again!”
Trail: Avalon Trail, A-Z Trail, Mt. Tom Spur, Willey Range Trail

“It was a humid one to start and I wasn't sure if I was going to get rained on or just spend my day in a cloud. It turned out that neither happened. The trails were quite wet from last night's rain so all the rocks were wet and there was more mud than usual. Footing was still pretty good and the water crossings were easy. I cleared all the spider webs along the way and didn't see anyone until I was on my way back from Willey and headed back up Field. I was in a cloud for Tom and Field but lucked out and got some in and out views off the viewpoint down from Willey's summit. As I returned, the skies were clearing so all those coming after me should have had some really nice views today. The trail was beginning to dry out upon my return as well. The icing on the cake was finding trail magic left for me in my car today! I suspect I know who left it and it totally made my day! <3”
