Arizona Monsoon

Summer Thunderstorms in Phoenix Can Be Dangerous

Monsoon is a weather condition that is actually defined as a season. In Arizona, we typically experience monsoon storms during the summer. Humidity levels increase, and the season is marked by wind storms, dust storms, and periods of heavy desert rains. These articles will help residents and visitors understand Arizona's monsoon, learn how to know when the monsoon has officially started, and get tips about living safely with monsoon activity.

A few words about tornados: yes, typically there are a few tornadoes in Arizona every year, but they are not as large, severe or as long-lasting as those that occur in the states with the nickname "tornado alley." More often than not, people who think they see a tornado here are usually experiencing a microburst.
