Arizona’s weather is a story of extremes – from the blistering desert heat of Phoenix to the snow-dusted peaks of Flagstaff – and the live forecast above shows exactly what’s happening right now across the Grand Canyon State.
What’s the weather like across Arizona today?
Right now, you’ll find a stark contrast between the low deserts and the high country. In Phoenix and Tucson, summer temperatures regularly climb above 40°C, with the overnight low often still sitting in the high 20s. Head north to Flagstaff or Sedona, and the air cools dramatically — Flagstaff sits at over 2,100 metres, so afternoons there can be 10–15°C cooler than in the Valley of the Sun. Check the Phoenix weather page for the latest on that desert heat, or see the Australia weather hub for broader context.
How does Arizona’s weather change through the year?
If you’re planning a visit, the monsoon season (July–September) brings brief but dramatic thunderstorms, especially to Phoenix and Tucson. Winter, meanwhile, transforms Flagstaff into a ski destination. For the most detailed outlook, look at the 14-day weather forecast Phoenix services provide, or check Tucson AZ weather for southern Arizona. The Phoenix weather next 30 days outlook helps you plan ahead, while the Phoenix weather radar 10-day view is useful for tracking incoming storms.
What’s the typical summer temperature in Arizona?
In the low deserts around Phoenix and Tucson, summer highs average 40–43°C from June to August. Overnight lows only drop to around 28°C, making evenings still quite warm. In Flagstaff, summer highs are a much more pleasant 27–30°C.
Does Arizona get snow?
Yes, but mostly in the high country. Flagstaff receives an average of around 200 cm of snow each winter. Sedona and the Grand Canyon get occasional snowfall, while Phoenix and Tucson almost never see snow — the last measurable snow in Phoenix was in 1937.
What’s the best time to visit Arizona?
Spring (March–May) and autumn (October–November) offer the most comfortable temperatures across the state. Phoenix is warm but not scorching, Flagstaff is mild, and both Sedona and Tucson are pleasant. Summers are extremely hot in the lowlands, but fine for mountain areas.
