Zion National Park weather is typical of southern Utah, with warm springs and autumns, mild winters, and very hot summers. Thunderstorms are frequent in the summer, causing the possibility of flash floods in Zion's many canyons. The statistics below are taken from the Zion Canyon area, where the vast majority of visitation takes place. Ample shade as the canyon narrows can moderate the temperatures in summer somewhat during most of the day.
