Flagstaff Weather in September

Flagstaff at 6,909 feet is Arizona's high-altitude surprise — a mountain city with four distinct seasons, significant snowfall (averaging 100 inches annually), and comfortable summers with highs typically in the 80s°F. Ponderosa pine forests surround the city and the San Francisco Peaks to the north generate unique orographic weather patterns.

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