Phoenix is baking under a brutal heat wave this Friday, July 24, 2026, with mostly clear skies and triple-digit temperatures expected to top out near 113°F. Heat index values could feel closer to 116°F, and an Extreme Heat Warning is in place through Monday, July 27, 2026, with overnight lows stuck in the low 90s that offer almost no relief.
What To Expect This Weekend
The heat turns up another notch on Saturday, with afternoon highs forecast to reach around 115°F. Southwest winds will pick up at times, and some spots could see gusts up to 30 mph, increasing the risk of blowing dust in outlying areas. Overnight, temperatures are expected to linger in the low 90s, a tough setup for anyone without air conditioning, according to the NWS Phoenix.
Monsoon Signal Returns Late Sunday
Moisture is forecast to creep back into the region late Sunday into Monday, bringing a slight chance of showers and isolated thunderstorms after about 5 p.m. Most storms should fire over higher terrain, but strong outflow winds could spill into the lower deserts and briefly kick up gusty winds or dust. Storms will be hit-or-miss, with localized lightning and short, heavy downpours where cells manage to form.
Cooling Centers And Local Relief
The City of Phoenix is running cooling centers, hydration stations, and respite sites across the city so residents have somewhere safe to escape the heat. Anyone who needs help finding a place to cool off can call 2-1-1 for assistance. For locations and hours, visit the City of Phoenix page.
How To Stay Safe
Limit outdoor activity during the hottest part of the day, keep water with you, and check on older neighbors, young children, and pets, who are especially vulnerable in this kind of heat. If someone shows possible signs of heat stroke, such as confusion, fainting, or a very high body temperature, move them to a cooler place and call 911 right away.
