Phoenix rolled into Monday under clear skies and comfortably mild mid-70s, but the cool start will not last. By this afternoon, the Valley is headed for triple digits, with highs expected to reach about 102°F and overnight lows stuck in the mid-70s, offering only modest relief.
What To Expect Today And This Week
Sunny, dry weather is on tap for much of the week, with daytime highs holding around 102–104°F through Thursday and overnight lows generally lingering in the mid-70s. That means limited cooling after sunset and a slow buildup of heat for anyone without strong air conditioning.
Winds start off on the lighter side, then pick up later in the week, with gusts near 20 mph possible over parts of the Valley and along the lower Colorado River. A slight midweek chance of isolated mountain storms is in the mix, mainly in far-eastern Gila County. According to the National Weather Service, dry air and above-normal temperatures are expected to hang around through much of the week.
Heat Relief And Safety
The City of Phoenix has cooling and respite sites open for anyone needing a break from the heat. The city runs a 24/7 respite center at 20 W. Jackson Street and partners with the Justa Center at 1001 W. Jefferson St. for extended hours, giving people more options when the sun is relentless.
Residents who need transportation or help locating a nearby site can call 2-1-1 or check the city's heat resources for a full list of locations and hours, as outlined by the City of Phoenix.
Daily Tips
With afternoon humidity likely hovering in the single digits to teens, the dry heat can sneak up quickly. Plan strenuous activity for early morning or evening, carry water everywhere, and never leave people or pets in a vehicle, even for a short errand.
Keep a close eye on outdoor work schedules and any local transit advisories. The next several days will bring heat that is not just uncomfortable but potentially dangerous for anyone without reliable cooling.
