Flagstaff Weather

Mid September to late November. Most fall days are sunny and warm with just a touch of crisp mountain air causing the leaves on the trees to change from green to gold. Aspen groves on the San Francisco peaks are a wonderful place to visit and enjoy the fall colors. Nights begin to feel very chilly and jackets are usually necessary after sunset.

Late November to mid March. Winter months in Flagstaff are usually very brisk with the average daytime temperature around 38 to 40 degrees Fahrenheit. Jackets and layers are a necessity, especially when the snow begins to fall! Luckily, even if a winter storm hits, the Arizona sunshine is bound to appear within a day or two and newly fallen snow will glisten under a beautiful bright blue sky.

Mid March to Late May. As the daily temperatures begin to rise, tulips and daffodils will speckle the town with their cheerful color. Days will usually be sunny; however, there is no such thing as a spring day without a chilly breeze. Night temperatures still drop down to almost freezing which makes layering clothing a good idea, especially closer to the evening.

Late May to Mid September. There is almost no better place to experience summer than in Flagstaff. Daily temperatures average in the mid seventies and nights are often enjoyed with a light sweater. Monsoons happen nearly every afternoon in late July and August. These intense rain storms disappear as quickly as they arrive and leave the earth fresh and damp and glowing in the summer sun.

Flagstaff enjoys 161 sunny days per year, 101 partly cloudy days (40 - 70% cloud cover) and 103 cloudy days (80 - 100% cloud cover). Be sure to pack a brimmed hat, comfortable sturdy shoes, a camera and a high SPF sunscreen year-round. At Flagstaff's high elevation, UV rays are more intense and damaging, increasing your risk for skin and eye damage. Sun protection at high altitudes is a must.
