Weather Report
Montana has something to offer visitors all year round. Non-residents may, mistakenly, think of Montana as an icebox. However, unlike many areas of the nation where winter settles in for keeps, Montana's cold spells are frequently interrupted by Chinook winds - warm dry winds that blow from the Rocky Mountains - and mild periods.

National Weather Service
Big Sky is located in the southwest corner of Montana surrounded by the magnificent Gallatin Range of the Northern Rockies. The elevation at the top of Lone Peak is 11,150 feet... the Mountain Village sits at 7,500 feet... the Meadow Village elevation is approximately 6,200 feet... and along the Canyon elevation is in the vicinity of 5,900 feet.
The advantage of Montana's weather system is that whether it's hot or cold, Montana is dry, and, therefore, neither oppressively hot nor oppressively cold.
Winter
Average winter temperatures hover around 20 F. There is very little humidity, which makes the snow less dense, lighter, fluffier and ultimately...more fun! Average annual snowfall is 400 inches.
Average daytime temperature in the state of Montana is 28 degrees Fahrenheit (-2 degrees Celsius) in January.
Montana's cold spells are frequently alleviated by Chinook winds.
Spring
May to July is the rainiest part of the warm season. Average annual precipitation is 15 inches, varying from 10 to more than 100 inches.
Summer
If you're primarily interested in the state's historical, cultural and sightseeing attractions, it is advisable to visit during the summer months.
The warmest temperatures occur in July, when the statewide range is 64-88°F (17-31°C), although most places will record 90°F (32°C) a few times each summer. Parts of Montana west of the Continental Divide are generally cooler than the southeast. On summer nights, temperatures can drop to a cool 50-60°F (10-15°C), so a sweater will be more than welcome!
Fall
Autumn is also an excellent time of year to visit Montana, when services are still available, but the crowds have diminished considerably.
Year-Roud
In general, visitors to Montana will be wise to bring along a variety of clothes in order to stay abreast of the quickly changing weather. Montana is seldom consistently hot or cold. Every season holds surprises. Montanans dress in layers so that they can peel clothes off or add them on as required.
