Weather by month

Bozeman

Montana

A cold mountain valley where winter is long and generous with snow, spring keeps getting snowed on, and summer shows up brief and brilliant.

The best time to come

July through September is the summer window — warm afternoons, cold nights, and Yellowstone within an easy drive. For snow, January through March is deep and dependable; just budget for the fact that April and May will still look like winter some mornings.
