Bozeman in January

June through September gives you the full Montana experience — hiking weather, Yellowstone access, and long summer days that stretch until 9 PM. July and August bring crowds to Yellowstone but perfect weather for everything else. September might be the secret sweet spot: fewer tourists, golden aspens, and daytime temps in the 70s. But winter has its fans too. Bridger Bowl gets 350 inches of snow annually, and lift tickets cost half what you'd pay in Colorado. The downside? Many Yellowstone roads close, and you'll need serious cold-weather gear for outdoor activities. Spring comes late — expect snow through April and muddy trails in May. Fall ends abruptly when the first big snow hits, usually by early November.
