Phoenix is under a sunny, dangerously hot sky today, Wednesday, July 8, with highs near 113°F and a heat index as high as 112 — the National Weather Service has an Extreme Heat Warning in effect, so save outdoor plans for the very early morning and keep strenuous activity off the schedule until well after sunset.
Today’s Setup
According to the NWS Phoenix office, a modestly strong high pressure ridge is parked over the Desert Southwest, with upper-level heights holding steady through Thursday. That’s keeping today and Thursday as the hottest days of the stretch, both peaking near 113°F. Overnight offers little relief this time: low-level moisture has crept in enough to stall nighttime cooling, so tonight’s low only dips to around 89-91°F, with central Phoenix neighborhoods likely staying in the low 90s before sunrise.
Best Window To Be Outside
If you’re hoping to get to Camelback Mountain, South Mountain, or a neighborhood walk in, the only realistic window is right at sunrise before the pavement and trailheads start radiating heat back up. By midday, even a quick walk to the mailbox needs water in hand. A patio umbrella 10ft over your backyard seating and a portable window AC unit for bedrooms can make the difference between a rough night and a livable one while lows stay near 90.
Rain, Wind, Fire, Or Heat Risk
The main story is heat, not storms — the Storm Prediction Center has no severe outlook for Arizona today. The NWS notes scattered shower and thunderstorm chances remain mostly confined to the higher terrain of eastern Arizona today, tapering further Thursday and Friday, so the Phoenix valley itself stays dry. Forecasters do expect the pattern to turn more favorable for widespread monsoon thunderstorms by early next week, worth watching if you’ve got weekend plans.
What To Wear Or Bring
Light, breathable clothing, sunglasses, and a wide-brim hat are non-negotiable. If a pool day is part of your plan to beat the heat, quick dry swim trunks are the move. For home backup during long, hot afternoons, the DARAN 288Wh Power Station is a handy way to keep fans and devices running if the grid gets stressed during peak demand.
Games, Concerts & Tickets
The Phoenix Mercury host the Indiana Fever on Thursday, July 9, at Mortgage Matchup Center — an indoor, air-conditioned escape from the heat, and a good excuse to grab tickets on SeatGeek plus Official team gear on Fanatics. Looking ahead, Fuerza Regida brings the This Is Our Dream Stadium Tour to Chase Field on Sunday, July 12; check our concert weather guide before you go, grab Find tickets on StubHub, and pack a Fuerza Regida t-shirt along with plenty of water for a stadium show in Phoenix’s summer heat.
Tonight’s Dinner
With highs this extreme, skip turning on the oven — a cold pasta salad or a quick stir-fry keeps the kitchen cool and dinner simple. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Thursday repeats today’s script almost exactly: sunny, near 113°F, with the Extreme Heat Warning continuing through Thursday evening. Relief is gradual after that, with slightly better monsoon moisture and a shot at more widespread storms building by early next week.
