Phoenix is baking under a sunny, 111°F Friday with an Extreme Heat Warning in effect through this evening, so the safest move is to save outdoor plans for early morning or after sunset. Heat index values are running as high as 110, and overnight lows only drop to near 88 before climbing back toward 90, meaning the metro gets almost no break to recover from the heat.
Today’s Setup
The National Weather Service Phoenix office says a subtropical ridge centered near the southern California coast is edging east today, which is actually pulling afternoon highs down a couple degrees from recent days — still, 109-112°F is expected across the south-central lower deserts. Winds stay light, 0 to 10 mph out of the west-southwest, under clear, sunny skies all day.
Best Window To Be Outside
Treat midday as a no-go. The coolest stretch of the day comes right around sunrise, before temperatures start their climb toward the afternoon peak. If you’re walking the dog, hitting South Mountain, or knocking out yard work, aim for before 8 AM. Saturday looks nearly identical with a sunny 109°F high, so the same early-morning rule applies through the weekend.
Heat Risk & Monsoon Watch
This qualifies as Major HeatRisk territory, largely because overnight lows near 88-90°F give the body little chance to recover. Rain chances stay essentially at zero for the Valley — 0% today, 4% Saturday — with the NWS noting shower and thunderstorm activity this weekend stays mainly over the higher terrain of eastern and southeast Arizona. Deeper monsoon moisture is expected to move into the region early next week, improving chances for more widespread storms across metro Phoenix.
Weekend Games, Concerts & What To Wear
The Arizona Rattlers host the Tucson Sugar Skulls on Saturday, July 11, at Desert Diamond Arena — since it’s an indoor arena, gameday heat isn’t the concern, but staying hydrated on the walk from the parking lot still matters; Get tickets on SeatGeek and pick up Official team gear on Fanatics before kickoff. Fuerza Regida brings the This Is Our Dream Stadium Tour to Chase Field on Sunday, July 12 — see our Fuerza Regida concert weather guide and grab a Fuerza Regida t-shirt or Fuerza Regida hat before the show. For beating the heat around the house, a talc free body powder and a kiddie splash pad for the kids both help, and the 2-Person Intex Floating Lounge with Cooler is a smart grab if pool time is on the schedule.
For dinner, keep it light and skip heating up the kitchen — pasta or a quick stir-fry works well on a day this hot. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Saturday runs just as hot, near 109°F, with Saturday night staying warm around 88°F. Monsoon moisture builds through early next week, so keep an eye on updates from the Phoenix weather forecast — after several dry, sunny days, better shower and thunderstorm chances look realistic by midweek. Until then, hydrate often, avoid the midday sun, and check on neighbors or pets without reliable air conditioning.
