Phoenix woke up to clear skies and bone-dry air Sunday, and the city is heading straight into the triple digits yet again. Forecasters are calling for a high near 109°F, with heat-index readings making it feel as hot as 114°F. Overnight lows will linger in the low 90s, which means very little relief once the sun goes down. An Extreme Heat Warning remains in effect through Monday, July 27, 2026, at 8:00 p.m.
Heat Through Monday
Across the lower desert, daytime highs will generally land between 107°F and 110°F, with a few spots nudging into the low 110s and heat-index values pushing it even higher. Monday night, July 27, 2026, carries a small chance of showers and thunderstorms between about 11 p.m. and 5 a.m., but any rain is expected to stay under a tenth of an inch and will not do much to cool things down. Gusty west winds could kick up brief bursts of 20 to 25 mph this evening, so if you work outside, build in extra breaks, according to the National Weather Service.
Outlook Into Next Week
There may be a short-lived dip in temperatures Tuesday and Wednesday before the ridge rebuilds late in the week. That pattern is expected to shove highs back into the low to mid 110s by Thursday, with temperatures peaking near 114°F on Friday and Saturday. Warm nights will limit any overnight cooldown, keeping heat risks elevated for anyone without reliable air conditioning.
Cooling Options And Safety
If you do not have air conditioning, head for a public cooling center or any other air-conditioned space, and call 2-1-1 for locations and transportation options. The city’s heat response page lists local cooling resources and practical tips; neighbors are encouraged to check on older adults, infants and anyone with health vulnerabilities. Drink plenty of water, avoid heavy outdoor activity during the hottest hours, roughly 10 a.m. to 5 p.m., and never leave children or pets in parked vehicles. Treat any signs of heat illness as an emergency and call 9-1-1 if needed. For more information see the City of Phoenix heat response page.
