Montana Climate & Weather

Montana Climate and Weather

Montana's east and west regions experience very different climates, separated by the Continental Divide, although generally the state tends to be hot and dry in summer and cold in winter, with snow. The western regions generally has a milder climate than the east, with warmer winters, cooler summers and lighter winds, and rainfall is more evenly distributed throughout the year. The east tends to have less humidity than the west, as well as more sunny days on average. Montana's cold winters are frequently broken by warm, windy spells in the east, known as 'Chinook' weather, which can last for several days at a time. The heaviest snowfall throughout the state is from November to March, and most cities receive an annual average of 30 to 50 inches (76 to 127cm). Rainfall is generally light, with most falling between May and July.
