Conditions summary as of September 2, 2026
Mount Willey is currently in decent shape with mild temperatures and light winds, but incoming weather makes timing important. Wednesday brings increasing wind, fog, and rising rain chances, with a shift to heavy rain and possible thunderstorms by Thursday, so an early start is advisable to beat deteriorating conditions.
Expect a noticeable cooling and wind increase from trailhead to summit, with winds picking up from about 9mph to 16mph near treeline and staying elevated to the summit; bring a wind layer for the upper mile and be prepared for wetter, slicker rock as you gain elevation.
Best Hiking Window
Wednesday early morning, shortly after sunrise, before afternoon winds and shower chances increase

Trail: Willey Range Trail, A-Z Trail, Mt. Tom Spur, Ethan Pond Trail
Conditions: Dry Trail, Wet/Slippery Rock
“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
Conditions: Dry Trail, Wet Trail, Wet/Slippery Rock, Standing/Running Water on Trail, Mud - Minor/Avoidable
“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”
Trail: Ethan Pond Trail, Willey Range Trail
Conditions: Wet/Slippery Rock, Mud - Minor/Avoidable
“Trail is wet in a couple of spots, a bit of running water here and there, nothing bad. Stairs as mentioned in rough shape. Willey Ridge trail is pretty relentless on the last mile to Willey, lots of hand over hand climbing, steep.”
