Weather is quite changeable, especially during the summer thunderstorm season and throughout the winter. Visitors should be prepared for all contingencies since getting caught in unexpected bad weather can be deadly.

The portion of the Flathead Valley in which the Range is located has a microclimate usually characterized by relatively mild winter temperatures and little wind. Snow cover melts quickly at lower elevations. Summer temperatures seldom exceed 100 degree but because of low humidity nights can be fairly cool. Freezing conditions generally occur from late November through March. Precipitation averages 12.63 inches annually at Range headquarters with slightly more at higher elevations. Low precipitation along with summer thunderstorms can lead to naturally occurring wildfires.
