Extreme Heat Warning in the Valley all week

and last updated

PHOENIX — Dangerous heat continues in the Valley this week.

An Extreme Heat Warning is in effect across much of central, southern and western Arizona through Friday, as temperatures continue to top 110 degrees each day.

Up north, the lower elevations of the Grand Canyon are also under an Extreme Heat Warning through Thursday.

Due to the extreme heat, every day this week is an ABC15 Weather Action Day. Take action to protect yourself, your family and your pets from these dangerously hot temperatures.

Stay hydrated, limit your time outside between 10 a.m. and 6 p.m. and bring your pets inside too. If you must be outside, wear lightweight, light-colored clothing, and take frequent breaks in the shade or air conditioning.

We are also tracking some monsoon moisture this week that could bring a few isolated storms to the Valley, especially in the late evening and overnight hours each day.

2026 Sky Harbor Rainfall to-date: 0.97" (-3.43" from average)

2026 Monsoon Rainfall to-date: 0.65" (-0.83" from average)
