About lightning in Arizona
Arizona’s thunderstorm season is the North American Monsoon, when a seasonal shift in winds pulls deep moisture north from July through September. Desert heat then erupts into dramatic storms with spectacular lightning, flash floods, and walls of blowing dust. These storms can strike from many miles outside the rain, a hazard for anyone caught in the open. The distance and trend to the nearest flash are the numbers that keep desert outings safe.
