Arizona weather forecast: High temps gradually warming up this week in Phoenix
PHOENIX - Temperatures will remain slightly below average around the state on Tuesday.
What To Expect:
In the Valley, high temperatures reached 105 degrees. The average this time of year is 106.
It was another breezy afternoon with gusts of 20 mph forecast in Phoenix. While it was still hot, this afternoon was about 13 degrees cooler than last Thursday and 5-10 degrees cooler than this upcoming weekend.
In northern Arizona, temperatures will only hit the 70s during the afternoon in spots like Flagstaff with lows in the 40s!
High pressure has the eastern half of the U.S. gripped in a heatwave, but high pressure will rebuild across Arizona by this weekend. As a result, temperatures will climb back to 110 degrees and hotter by Sunday following a slow climb from 105 Wednesday to 108 Friday and 109 Saturday in Phoenix.
As for rain chances, they're unlikely in Phoenix, but possible in far southern and eastern Arizona! Monsoonal moisture has been soaking parts of New Mexico and West Texas. In fact, a flood watch lasts until Wednesday. For southeastern Arizona, a few showers and thunderstorms are expected through today. The storms could extend as far west as eastern Pinal County and eastern Gila County near Globe. Tucson may also see nearby showers or thunderstorms. This week, spotty shower chances will continue over southeastern Arizona.
What's next:
For now, there's a low 10% chance of showers approaching the Valley by Independence Day weekend. It's too early for exact timing and details, but certainly something to watch!
Morning Weather Forecast - 6/24/25
Tuesday will be a warm and sunny day in the Valley. We'll see a high near 104 degrees in Phoenix.

Driving in extreme temperatures
The Arizona Department of Transportation’s tips for driving in extreme temperatures include:
Have sun protection: In addition to an umbrella, take sunscreen and a wide-brimmed hat and wear loose-fitting, light-colored cotton clothing.
Fuel up: Keep your tank at three-quarters full. Running out of gas, especially in a remote location, is dangerous in extreme heat.
Hydrate: Take a cooler to keep extra drinking water cold, and consider adding several frozen bottles of water to use for cooling off or to thaw and drink if needed. Make sure everyone, including pets, stays hydrated.
Get help: If your vehicle breaks down in extreme heat, call for assistance right away to reduce wait time, and run the AC. If the AC isn’t working, roll down all windows.
Wait safely: If the temperature inside your vehicle becomes too hot, everyone, including pets, should exit carefully and seek out or create a shaded area as far away from the travel lanes as possible. Be careful walking on the road surface, which can be hot enough to burn skin. Keep your shoes on and try to keep your pets’ paws off the pavement. If you are stopped along the highway, raise the front hood and turn on hazard lights. Please keep in mind that parking in tall brush can start a fire.
Check your vehicle: You can help avoid breakdowns and blowouts by making sure your vehicle is in good operating condition. Check your air conditioner and coolant levels, top off any vital engine fluids and make sure your battery is up to par. Check your tire pressure, as the combination of under inflated tires and hot pavement can lead to a blowout.
