Arizona weather forecast: October welcomed by warm temps
PHOENIX - We're warming up over the next several days, before a weekend cool down arrives.
Today:
Wednesday was a sunny and dry day across all of Arizona. Temperatures stayed similar to Tuesday, with highs in the upper 90s in the Valley.
Thursday and Friday:
As high pressure builds over New Mexico and northern Mexico on Thursday, temperatures will warm up a few more degrees. We will see a low of around 75 in the Valley on Thursday morning, and a high temperature around 100 degrees. Skies will be sunny and dry, statewide.
Overnight temperatures will still remain fairly comfortable in the middle 70s the next few mornings.
Friday will be another warm day, with highs around 100 degrees and plenty of sunshine. The winds will pick up across Arizona, with gusts up to 20 mph in the Valley, and up to around 40 mph in the high country.
Isolated showers will be possible in far eastern Arizona.
The Weekend:
A cold front will cool temperatures back into the low to mid 90s on Saturday and Sunday.
High pressure will shift eastward and give way to a large area of low pressure and an associated trough. This system, dropping in from the Northwest, will bring cooler air and breezy conditions. The forecast high will drop to 93 degrees on Saturday and Sunday. Morning temperatures fall into the 60s by Sunday morning, too. It will be a sunny weekend with dry conditions across the Valley and much of the state.
Looking Further Ahead:
Next week, temperatures will remain near-normal in the middle 90s for much of the work week. Late next week brings the next notable chance for showers over parts of Arizona.
Morning Weather Forecast - 10/1/25
The first day of October will be a warm one in the Valley with a high near 97 degrees.

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.
