The annual precipitation is 8.56 inches, and most falls during July, August, and September. This low rainfall is due to a pronounced rain shadow effect caused by the Sierra Nevada Mountains. On the west side of the mountains, the air rises, cools, and drops its moisture. When this air descends on the east side of the mountains, it warms, expanding and taking on more moisture.
The climate in Arches National Park is also affected by the elevation of the park. The park ranges in elevation from 4,085 feet at the Colorado River to 5,653 feet at the top of Elephant Butte. The higher elevation areas of the park are cooler than the lower elevation areas.
The climate in Arches National Park is also affected by the topography of the park. The park is located in a region of canyons and mesas. The canyons are typically cooler than the mesas because the air is trapped in the canyons and cannot escape. The mesas are typically warmer than the canyons because the air can circulate freely.
