Phoenix woke up to clear, dry skies on Tuesday, May 19, 2026, and the desert sunshine is not letting up anytime soon. Today’s forecast calls for a high near 91°F, with overnight lows hanging out in the upper 60s.
What To Expect This Week
Mostly sunny skies will stick around through midweek as the heat slowly cranks up. The National Weather Service Phoenix is calling for highs near 91°F today, climbing into the mid 90s by Thursday and the upper 90s by Friday.
By the weekend, things get serious: readings are expected to reach around 100°F on Sunday and near 101°F on Memorial Day, Monday, May 25, 2026. Humidity will be very low, often below 15%, and there is no measurable rain in the cards through early next week, according to the National Weather Service.
Afternoon Breezes And Fire Weather
Afternoons will come with the usual upslope breezes, with gusts generally in the 15 to 25 mph range and locally higher winds along the Colorado River corridor. When you mix those gusts with very dry air, fire weather concerns increase in brushy or rural areas.
That means it is a good time to skip open burns and be extra careful with yard debris or anything that could spark. Anyone working outside should aim to tackle the hardest jobs in the early morning or later in the evening when temperatures are at their coolest.
Heat Relief And City Resources
The City of Phoenix flipped the switch on its network of heat relief sites and cooling centers on May 1 to give residents a place to escape dangerous heat this season. If you need transportation to a cooling center or other heat relief, you can call 2-1-1 for help, according to the City of Phoenix.
During the hottest part of the day, roughly from noon to 6 p.m., staying safe means water, shade, and frequent breaks if you are outdoors.
No Watches Or Warnings
There are no active watches or warnings in place for the Phoenix metro area right now, although forecasters are keeping a close eye on conditions as temperatures build into next week.
Before heading out to big outdoor events or long stretches in the sun, check the latest short-term forecasts and follow local guidance on heat safety.
