Extreme Heat Warning Grand Canyon / Page Areas

Monsoon Moisture is On the Way!

Most areas below 5000 feet in Arizona will exceed 100 degrees into the weekend, with temperatures pushing 110+ degrees below 4000 feet. An Extreme Heat Warning remains in effect for the Grand Canyon below 4000 ft through Sunday and for Marble/Glen Canyons & Page for Saturday and Sunday.

If you've been waiting for the summer storms, you won't have to wait much longer. We are tracking a surge in monsoon moisture heading into northern Arizona over the next few days. Friday and Saturday (July 10-11) will start off with quiet conditions, as minimal monsoon moisture means we'll only see isolated showers and thunderstorms mostly confined to the Mogollon Rim and White Mountains. However, the surge officially begins on Sunday (July 12) as moisture levels start climbing into "low-grade" monsoon conditions, bringing scattered showers and thunderstorms along and south of the Mogollon Rim. By Monday and beyond (July 13+), active monsoon conditions fully arrive as deep moisture settles over the region, leading to widespread, scattered shower and thunderstorm activity across northern Arizona. Keep an eye on the sky and stay weather-aware as we head into early next week!
