Southern Arizona Monsoon
The Arizona monsoon is a pattern of pronounced increase in thunderstorms and rainfall over large areas of the southwestern United States and northwestern Mexico, occurring annually from June 15 through September 30. Monsoon is actually a season, and the word monsoon in Arizona is interchangeable with the word summer.
During the monsoon, thunderstorms are fueled by daytime heating and build up during the late afternoon-early evening. Typically, these storms dissipate by late night, and the next day starts out fair, with the cycle repeating daily.
Monsoon storms in the Green Valley area almost always include spectacular lightning displays. When these storms occur over the Santa Rita Mountains to the east of Green Valley at night, the views can be unforgettable.
