Climate & Weather

• The Mountain: High-altitude snowpack is typically at its deepest. This is "prime time" for ski mountaineering and spring corn snow.
• The Town: Lower-elevation hiking trails, like those at Hedge Creek Falls, begin to clear of snow, and the region's famous waterfalls are at their peak flow from the spring melt.

• The Mountain: The climbing season is in full swing. While the base is warm, the summit can still experience freezing temperatures and sudden lenticular cloud formations—the mountain literally creates its own weather.
• The Town: Humidity is exceptionally low, making even the hottest days comfortable. This is the best time for swimming at Lake Siskiyou or strolling through the Dunsmuir Botanical Gardens.

• The Mountain: Climbing routes become "icy" and more technical as the seasonal snow melts away to reveal blue glacier ice. Early dustings of new snow can occur as early as late September.
• The Town: Ideal for golfing at or visiting the Siskiyou County Museum in Yreka. Daytime highs settle into a comfortable 60s to 70s°F.

• The Mountain: High winds and heavy snowstorms are common. Access is limited to experienced winter travelers and snowshoers.
• The Town: The KOA and surrounding areas transform into a quiet, snow-covered retreat. Average highs are in the 40s°F, with lows dropping into the 20s°F.
