Arizona RV Camping by Month

Elevation is Arizona's thermostat: every 1,000 feet up is roughly 3–4°F cooler. Here's the honest month-by-month answer, from the desert floor to 7,000 feet.

Temperatures below are official NOAA 1991–2020 climate normals for a weather station at each destination — not guesses. Verdicts are our read of those numbers after 17 years of renting RVs for these exact trips. Checked 2026-09-06.

Month by month: where to go

Jan: Desert season. Phoenix, Tucson and the Colorado River run high-60s days — this is what snowbirds come for. The high country is a snow zone (Flagstaff 43/18).

Feb: Still peak desert weather everywhere below ~3,000 ft. Spring training crowds arrive late month — book pickup dates early.

Mar: The sweet spot: deserts mid-70s, Sedona opens up (68/40). High country still freezes at night and can still snow.

Apr: Everything below the Mogollon Rim is prime. Sedona is at its best. Up high, days turn pleasant but nights still drop below freezing.

May: The desert crosses 95° — last comfortable low-desert month is behind you by Memorial Day. Payson and the Rim country hit their stride.

Jun: Go up. Phoenix averages 104°; Show Low averages 84° and Flagstaff 79° with bone-dry skies. Peak wildfire caution — check restrictions before you burn anything.

Jul: Desert floor is extreme (Phoenix 107°, Lake Havasu 109°) and monsoon storms fire most afternoons statewide. Camp at 6,000+ ft and plan mornings.

Aug: Monsoon peak. High country days stay low-80s with near-daily afternoon thunderstorms — never camp in a wash, and expect lightning after lunch.

Sep: Monsoon tapers early in the month. High country is prime; the desert still runs ~100° the first weeks — wait for October down low.

Oct: The other sweet spot: deserts drop back to the 80s, high country turns crisp with first freezes. Arguably the best all-around month in the state.

Nov: Desert season returns in full. First snows reach Show Low and Flagstaff — high-country trips become snow trips.

Dec: Mild desert days (Phoenix 66/45), cold desert nights. The high country is genuine winter — icy roads and hard freezes at the Canyon.

The numbers, by elevation

Average high / low, °F. Prime — ideal camping weather · Cool — great days, pack for cold nights · Cold — hard freezes, snow likely; winter camping only · Warm — fine with shade and water · Hot — plan AC, hookups or a generator · Extreme heat — we send renters uphill instead

Stations: Lake Havasu City, Phoenix, Tucson, Sedona, Payson, Show Low, Grand Canyon South Rim, Flagstaff — NOAA/NWS U.S. Climate Normals, 1991–2020. Temperatures are NOAA/NWS 1991-2020 U.S. Climate Normals for the named station at each destination, cross-checked against independent sources before publishing.

Monsoon and snow, honestly

Mid-June through September, monsoon storms build most afternoons statewide — lightning, sudden wind, flash flooding. Plan drives and hikes for mornings and never camp in a wash. From November through March the high country (Show Low, Flagstaff, the Grand Canyon rim) is genuine winter: snow, ice and hard freezes. The deserts are the whole point of an Arizona winter — that’s snowbird season.

The high-country cheat code

Our Show Low lot sits at 6,400 ft in the White Mountains — in summer you can pick up an RV already in the cool country instead of towing up the Rim. The rest of the year, all seven Arizona lots put you an easy drive from whichever elevation the month calls for, or we deliver and set up wherever you’re headed. Trip ideas: where we send our own renters within 2 hours of Phoenix and the Arizona event calendar.

Common questions

What is the best month to rent an RV in Phoenix?

October through April is desert season — highs in the 60s to 80s. March–April and October–November are the best all-around windows: warm desert days AND usable high country. Summer isn't a no; it just means camping at elevation instead of the valley floor.

Is July too hot for an RV trip in Arizona?

On the desert floor, honestly, yes for dry camping — Phoenix averages 107° and nights stay in the 80s, so boondocking without hookups is miserable and hard on batteries. With full hookups and AC it's doable. The better answer is elevation: Payson averages 93°, Show Low 85° and Flagstaff 82° in July — 20 degrees cooler, two hours up the road.

Where can I camp in Arizona in summer without cooking?

Above roughly 6,000 feet: the White Mountains around Show Low, the Mogollon Rim, Flagstaff and the Grand Canyon's South Rim all average low-to-mid 80s in July and August, with cool nights. Our Show Low lot sits right at 6,400 ft in the White Mountains, so you can pick up already in the cool country instead of towing up the Rim.

When is Arizona monsoon season, and does it matter for RV trips?

Mid-June through the end of September, peaking in July and August. It matters: storms build most afternoons, with lightning, sudden wind and flash flooding. Plan drives and hikes for mornings, never park or camp in a wash, and give storms an hour — they usually pass.

When does it snow in Show Low and Flagstaff?

Typically November through March, with late-season snow still possible into April up high. Show Low averages ~26 freezing nights in January; Flagstaff winters are genuinely snowy.
