Weather, in the park service’s words
Arches is part of the Colorado Plateau, a "high desert" region that experiences wide temperature fluctuations, sometimes over 40 degrees in a single day. The temperate (and most popular) seasons are spring (April-May) and fall (mid-September-October), when daytime highs average 60 to 80 F and lows average 30 to 50 F. Summer temperatures often exceed 100 F, making strenuous exercise difficult. Winters are cold, with highs averaging 30 to 50 F, and lows averaging 0 to 20 F.
