National Park

Spring As the park warms, more areas of the wilderness become accessible. One of the first areas without snow is the Southwest Desert of the park. La Verkin Creek is often snow free by mid-March, and the East and West Rims are usually snow free by early April. In an average year, high water due to snowmelt makes The Narrows impassable until late May.

Summer Zion National Park is hot through the summer months with temperatures regularly exceeding 100°F. Even higher elevation areas such as the Kolob Canyons and West Rim can see high temperatures in excess of 90°F. Visitors must pay constant attention to the possibility of thunderstorms and lightning. The park typically experiences a monsoon season from mid-July through mid-September with an increased risk of severe thunderstorms and dramatic flash flooding. In the summer, the National Weather Service issues a daily Flash Flood Potential Rating for multiple areas in Utah.
