Flagstaff's 7,000-foot elevation creates four distinct seasons, cool nights and weather that can change quickly throughout the year.

The easiest way to stay comfortable is to dress in layers and adjust throughout the day. Whether you're hiking, sightseeing, dining downtown, skiing or visiting during summer monsoon season, this guide explains what to wear and pack for Flagstaff in every season.

Flagstaff Clothing & Weather Basics

Layers are the key to dressing comfortably in Flagstaff. The high elevation and dry air can produce large temperature changes between afternoon and nighttime, so clothing that feels comfortable during the day may not be warm enough after sunset. A short-sleeve shirt, long-sleeve layer, sweater or fleece and lightweight jacket provide flexibility during much of the year.

Comfortable walking shoes are useful in every season. Also bring sunglasses, sunscreen and a hat because sunlight is more intense at higher elevations, even when temperatures feel cool. Check the current forecast before leaving home because snow, thunderstorms, wind and rapidly changing temperatures can affect what you need to wear.

What To Wear In Flagstaff In Spring

Spring in Flagstaff can range from mild and sunny to cold, windy or snowy, especially early in the season. Daytime temperatures gradually warm, but mornings and nights often remain cold. Late-season snow is possible, so visitors should not pack for warm Arizona weather alone.

Wear long pants with a shirt and sweater, fleece or light jacket that can be removed as the day warms. During colder spring periods, add a heavier jacket, gloves and water-resistant shoes or boots. Sunglasses and sunscreen are useful even on cool days.

What To Wear In Flagstaff In Summer

Flagstaff summers are pleasantly mild compared with Phoenix and other lower-elevation Arizona destinations. Shorts, lightweight pants, T-shirts and breathable clothing are usually comfortable during the day, but evenings can cool quickly enough to make a light jacket, sweater or fleece worthwhile.

July through September is Arizona's summer monsoon period, when thunderstorms can develop quickly. Pack a lightweight rain jacket or waterproof shell and avoid relying on sandals alone if hiking. A hat, sunglasses and sunscreen are important because of the strong high-elevation sun.

What To Wear During Flagstaff Monsoon Season

Summer thunderstorms can develop rapidly in and around Flagstaff, particularly during July, August and early September. A clear morning does not guarantee a dry afternoon. Carry a lightweight waterproof jacket when hiking or sightseeing and choose footwear with good traction if trails may become wet.

Thunderstorms can produce lightning, strong wind, heavy rain and localized flooding. If thunderstorms are developing, avoid exposed ridges, peaks and open areas and adjust outdoor plans according to current weather conditions.

What To Wear In Flagstaff In Fall

Early fall often brings comfortable days and noticeably cooler mornings and evenings. September may still feel mild during the afternoon, while October brings progressively cooler conditions and increasing chances of freezing nighttime temperatures.

Long pants, layered shirts, a sweater or fleece and a light-to-medium jacket are good choices during early fall. By late October and November, pack warmer outerwear, especially if you plan to be outside before sunrise, after sunset or at higher elevations.

What To Wear In Flagstaff In Winter

Winter in Flagstaff is cold and snowy, so visitors should pack for genuine winter conditions rather than typical Arizona desert weather. Wear insulated layers, long pants, a warm winter coat, gloves, a hat, heavy socks and water-resistant or waterproof footwear.

If you plan to ski, snowboard, sled or spend extended time in the snow, add waterproof snow pants, insulated gloves, winter boots and moisture-wicking base layers. Roadside snow and melting ice can also make waterproof footwear useful for ordinary sightseeing around town.

Dress For Flagstaff's High Elevation

Flagstaff sits at approximately 7,000 feet elevation, which means stronger ultraviolet exposure, dry air and cooler temperatures than many Arizona visitors expect. Wear sunscreen, sunglasses and a hat even when the air feels cool, and use lip balm and moisturizer if you are sensitive to dry conditions.

Visitors arriving from lower elevations may also notice shortness of breath or fatigue during strenuous activity. Drink plenty of water, allow time to adjust and pace yourself during hikes and other outdoor activities.

Downtown Flagstaff: Casual clothing and comfortable walking shoes work well for sightseeing, shops and restaurants. Bring an extra layer for evenings.

Camping: Pack significantly warmer nighttime clothing than daytime temperatures might suggest, including a warm layer and weather-resistant outer shell.
