Bozeman Weather in September

Bozeman in the Gallatin Valley is one of America's fastest-growing cities, driven by tech migration and outdoor recreation. Montana State University anchors the city, which sits at 4,820 feet between the Gallatin Range to the south and the Bridger Range to the north. Cold mountain winters and warm dry summers make it highly desirable.

Excellent shoulder season — warm with fewer tourists in many destinations.
