Conditions summary as of October 17, 2026
Cold, dry, clear conditions with strong, gusty west-northwest winds make for a chilly hike, with wind chills in the teens to 20s. Sunrise is at 7:00 AM and sunset at 6:00 PM, so plan around an 11-hour day. Light rain over the past 48 hours and overnight lows near 29°F mean wet leaves may be frosty or icy in the morning.
Trailhead and summit are nearly identical in elevation, so conditions barely change; the freezing level is well above the summit area at times but temps start near 29°F, so dress in warm layers early and shed as it warms into the mid 40s. Wind is the main variable on open ledges.
Best Hiking Window
Late morning through mid-afternoon on Saturday, once frost has melted and temperatures reach the 40s; Sunday offers clear skies and lighter precipitation risk for a similar midday window
