Phoenix is under an Extreme Heat Warning on Wednesday, June 24, with a high near 111°F — roughly five degrees above normal — and dangerous heat continues through Thursday. If anything outdoors is on your calendar today, read this before you head out.
Today’s Setup
A powerful upper-level high is anchored just southeast of the Valley, generating near-record pressure heights. The National Weather Service notes conditions could have pushed us toward 115°F, but elevated moisture and mid-level cloud cover are keeping the lid on in the 108–111°F range. Expect mostly sunny skies, a high near 111°F (easing to around 109°F by afternoon), and light west-northwest winds 0 to 10 mph. Wednesday night stays miserable with a low around 88°F — the heat does not let up after dark.
Best Window To Be Outside
Realistically, you have until about 7 AM. Early walkers near South Mountain Park or along the Arizona Canal should wrap up before the heat climbs. Phoenix asphalt reaches temperatures that burn paws long before most people feel the full brunt, so keep dog outings short — a backyard dog splash pad is a smart investment this week. If you have a pool, the 2-Person Intex Floating Lounge with Cooler deal is worth a look at just $24 on Amazon. For anyone who must be outside mid-day, ventilated workout shorts men are designed for desert conditions, but no gear replaces getting indoors during peak hours.
Heat Risk and Fire Danger
Extreme Heat Warnings remain in effect through Thursday, with the National Weather Service flagging Moderate Heat Risk Valley-wide and localized Major Heat Risk in some areas. Hydrate aggressively, never leave kids or pets in a parked car, and check on elderly neighbors.
Looking ahead to Friday and Saturday: Fire Weather Watches have been issued for the Lower Colorado River Valley and Tonto National Forest as drying conditions and increasing winds arrive. Now is a good moment to test your smoke detector combo pack and review your household emergency plan.
Events This Week — All Indoors, All Smart
Tonight, Iration plays the Arizona Financial Theatre (June 24) and Disney’s Beauty and the Beast (Touring) opens at ASU Gammage — both great air-conditioned escapes from the heat.
Friday, June 26 is packed: Nate Bargatze’s Big Dumb Eyes World Tour lands at the Mortgage Matchup Center, and 5 Seconds of Summer’s EVERYONE’S A STAR! World Tour takes over Desert Diamond Arena. A 5 Seconds of Summer t-shirt is the right fit for the show — grab tickets on SeatGeek before they’re gone.
Monday, June 29, the Arizona Diamondbacks host the San Francisco Giants at Chase Field — the retractable roof and AC make it one of the best heat escapes in the Valley. Represent in your Official team gear on Fanatics and enjoy baseball the air-conditioned way.
Dinner Tonight
Skip firing up the outdoor grill in 111°F heat. A quick pasta or veggie stir-fry on the stovetop keeps cook time short and the kitchen cooler. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered right to your door.
Next Few Days
Thursday mirrors today — sunny and near 111°F with south winds gusting to 20 mph. Fire weather concerns ramp up Friday and Saturday for outlying desert areas. Keep checking the Phoenix weather forecast for updates as we tick closer to monsoon season. Stay cool out there, Phoenix.
