Many Flagstaff.com visitors write in asking what the weather will be like when they plan to visit. We've received requests for weather in March, July, September and December, so we thought we'd create a season-by-season guide to Flagstaff weather. You’ll marvel at everything Flagstaff’s four season climate has to offer – from glowing golden aspen in autumn to terrific snow for skiing and snowboarding in winter, from spectacular spring wildflowers to a cool mountain respite in summer. Get our tips on what to pack and what to wear for Flagstaff's alpine weather, as well as annual average temperatures and insider tips on what to do in Flagstaff for each season.
Summer Season - June through September
Summer rivals winter for Flagstaff's busiest tourist season for three reasons:
1) The weather typically clear (or at least partly sunny) and perfectly warm-but-not-hot. Average highs in the mid 70s to 80s and evening lows in the 40s and 50s. Expect refreshing summer showers in July and August and soak in the smell of rain, pine forests and fresh mountain air.
2) Summer is the peak season for Grand Canyon visitors; the vast majority of Grand Canyon 5 million annual tourists descend upon the National Park between May and October each year. Since Flagstaff is one of the Gateways to the Grand Canyon, you can see why Flagstaff is a busy and energized city in the summertime.
3) Summer is the time for heat-seared Phoenix-area residents to escape to Flagstaff and find relief in the 80-degree weather!
Pack plenty of tank tops or short-sleeved shirts, shorts and sandals for walking around town. You'll want close-toed shoes or hiking boots for any open-air Flagstaff-to-Grand Canyon tours or activities like hiking or mountain biking. Bring a light jacket for the evenings and hiking in the upper elevations and at the windy Grand Canyon. And better make it water-resistant; you can expect summer rain showers.
Be sure to bring your swimsuit, towel, sunscreen and water-shoes so you can wade along in Oak Creek, especially if you visit Slide Rock State Park - the area's most popular section of Oak Creek Canyon, the beautiful 25-mile winding stretch of Highway 89A that connects Flagstaff and Sedona. Families and individuals love swimming, wading and of course sliding in the cool Oak Creek waters.
Insider Visitor Tip: A handful of summer arts & crafts, music & science festivals take place in July, August & September every summer, so check out our Flagstaff Calendar of Events for dates and details.
Fall Season - October through November
Pack & wear several light layers including shorts and pants, short and long-sleeved shirts and a medium-weight sweater or jacket for evenings. Again, sandals are comfortable for daytime activities in town but shoes or boots are best for recreational activities.
Insider Visitor Tip: Do not let your autumnal visit be limited to just Flagstaff. Be sure to take a scenic drive down Highway 89A through Oak Creek Canyon headed for Sedona. There are great leaf-peeping opportunities in the canyon (and all around Flagstaff) from mid-September through mid-October. Definitely check out towns surrounding the area - known as the Verde Valley - like Sedona, Cottonwood, Clarkdale and Camp Verde. There are dozens of quintessential small-town fall festivities like Oktoberfests, hayrides, apple picking, train rides, pumpkin patches and trick-or-treating mischief.
Winter Season - December through March
1) Skiing! From the time the first snow hits in early December through about March, the Arizona Snowbowl located above Flagstaff on Mount Humphries is abuzz with skiers and snowboarders, locals and tourists, families and individuals.
2) The fewest crowds of the year at the Grand Canyon South Rim (the North Rim is closed in the winter.) Picture the Grand Canyon dusted with white - spectacularly peaceful.
Insider Visitor Tip: Be sure to participate in the handful of area holiday events like the Holiday Lights Display at the Little America Hotels; a tour of Riordan Mansion, adorned in turn-of-the-century decor and fragrant boughs; Red Rock Fantasy festival of lights down in Sedona; the Grand Canyon Railway's "Polar Express" from Williams (an easy 39 miles west of Flagstaff); or the Verde Canyon Railroad's Santa Claus-themed train ride (in Clarkdale; 55 scenic miles southwest of Flagstaff) and more.
Spring Season - April through May
Pack light layers like long pants (or shorts, if you choose) long-sleeved t-shirts and light sweaters and jackets. You will want and need close-toed shoes for walking around town as well as hiking, biking or other outdoor recreation. You'll want to peel off jackets and sweaters in the middle of your daily tours or activities, but they'll come back on in the evenings.
Insider Visitor Tip: Be sure to book your Grand Canyon tour or activities from Flagstaff several months in advance. You don't want to miss out on the most popular activities as the Grand Canyon's busiest season starts to ramp up.
Now you're all set for your Flagstaff vacation... you know what to pack and what to do to take advantage of Flagstaff, Arizona's weather, casual culture and insider tips.
