Phoenix is under a sunny sky today with a high near 113°F, and the National Weather Service has an Extreme Heat Warning in effect for the lower deserts through Thursday — so plan errands, yard work, or a walk around Encanto Park for before 8 AM or after 7 PM, not the middle of the day.
Today’s Setup
A strong subtropical ridge is parked right over the region, pushing highs to 113°F today and again Wednesday, with the National Weather Service’s Area Forecast Discussion noting peaks could reach as high as 116°F Wednesday or Thursday. Overnight lows won’t offer much relief either — expect it to stay near 87-90°F after sunset, with central Phoenix running toward the low 90s because of that added low-level moisture limiting nighttime cooling. Skies stay sunny and dry outside of an isolated shower chance over the high terrain of eastern Arizona; the Phoenix metro itself should stay rain-free through Friday.
Best Window To Be Outside
If you’re heading to South Mountain or Camelback, sunrise is really your only realistic window — forecasters expect heat index values as high as 110-111°F by afternoon. Anything outdoors (dog walks, patio time, the kids’ bikes) should happen before mid-morning.
Heat Risk Through Thursday
This is a Major Heat Risk setup, and the Extreme Heat Warning covers south-central and southwest Arizona through Thursday. Take it seriously: check on elderly neighbors, never leave kids or pets in a parked car, and keep AC running — with demand this high, it’s worth having a backup like the DARAN 288Wh Power Station Just $90 for Prime Members on hand in case of an outage.
What To Wear Or Bring
Lean into moisture wicking undershirts men and ventilated workout shorts men if you’re outside at all, plus no show socks bamboo for anything requiring closed shoes. Carry an insulated water bottle everywhere — hydration is the single biggest factor in staying safe this week.
Games, Concerts And Tickets
Good news: several of this week’s big events are indoors, which is a smart heat escape. The Phoenix Mercury host the Indiana Fever on July 9 at the climate-controlled Mortgage Matchup Center — grab tickets on SeatGeek and pick up Official team gear on Fanatics. JOJI: SOLARIS lands at the same arena July 10 (full concert weather guide) — a Joji t-shirt makes a good souvenir. And Fuerza Regida brings the This Is Our Dream Stadium Tour to Chase Field on July 12 (see our concert weather breakdown); find tickets on StubHub and grab a Fuerza Regida t-shirt, Fuerza Regida hoodie, or Fuerza Regida hat before you go.
Tonight’s Dinner
With the house already working overtime to stay cool, skip turning on the oven — a quick stovetop stir-fry keeps the kitchen from heating up further. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door, and Amazon Fresh groceries makes restocking easy without another car trip in this heat.
Next Few Days
Wednesday holds at 113°F with continued Extreme Heat Warning conditions, and Thursday could edge even higher before the ridge finally shifts west and brings some, if modest, relief by the weekend. Check out more outdoor gear deals to stay prepped for the rest of monsoon season.
