Climate

Weather in the park varies greatly with elevation, and even at the same elevation may differ by over 30°F between day and night. During the spring the weather is very unpredictable, with stormy, wet days common, although warm, sunny weather may occur too. Precipitation peaks in March. Summer days are hot (95-110°F), but overnight lows are usually comfortable (65-70°F). Afternoon thunderstorms are common from mid-July through mid-September, making flash floods (if hiking in one) in the canyons a danger. Autumn days are usually clear and mild with cool nights. Winter storms bring rain or light snow to Zion Canyon, but heavier snow to the higher elevations such as the east side of the park, Kolob Terrace and Kolob Canyons. Clear days may become quite warm, reaching 60°F; nights are often in the 20s and 30s. Winter storms can last several days and cause roads to be icy, but the Zion-Mt. Carmel Highway is owned by the park and the NPS keeps it in excellent condition even in the winter.
