Arizonaâs monsoon is the northern extent of the North American Monsoon, which begins in early June in central and southern Mexico.The monsoon is a season, during which the dry westerly winds that persist through fall, winter and spring shift to moist southerly winds, bringing thunderstorm activity into Arizona.
