Phoenix is under an Extreme Heat Warning this Tuesday, June 23, with a dangerous high of 111°F under clear sunny skies — if you need to be outside today, your safe window closes well before 9 AM.
Today’s Setup
A powerful upper-level high pressure system centered over Southeast Arizona is driving this week’s heat, according to the National Weather Service. Extreme Heat Warnings cover the Phoenix metro through Thursday, with forecast highs ranging from 107 to 114°F. Winds will stay light from the west, 0 to 10 mph — no meaningful cooling breeze to speak of. Tonight’s low only falls to around 86°F, which means little overnight relief for those without reliable air conditioning.
Best Window To Be Outside
If you want to squeeze in a round of golf, your alarm needs to go off before 6 AM. A golf hat visor cuts the early-morning glare, and a golf glove men leather gives you better grip before the heat sets in. Once the sun is up, head indoors. Camelback Mountain and South Mountain Park trails should be skipped entirely during daylight hours — there is no safe midday window today.
Heat Safety — What NWS Is Saying
The National Weather Service flags Moderate Heat Risk today, with localized Major Heat Risk arriving Wednesday and Thursday. Check on elderly neighbors and anyone in the family without a working AC unit. The City of Phoenix has cooling centers open across the metro. Keep pets inside — pavement at 111°F can burn paws within seconds, and shaded asphalt in Tempe and Scottsdale won’t be much better.
Tonight’s Events — All Indoors
The good news: tonight’s entertainment lineup is fully air-conditioned. A$AP Rocky brings the Don’t Be Dumb World Tour to Mortgage Matchup Center this evening — grab an A$AP Rocky t-shirt and Find tickets on StubHub if you haven’t locked in seats yet. Bob Dylan also performs tonight at the intimate Arizona Financial Theatre downtown. Both venues are exactly where you want to be on a 111°F night.
On Wednesday, June 24, Killswitch Engage hits the Marquee Theatre — another great indoor option right in the thick of the heat wave.
Grill After Sunset
Wait until after 7 PM when temps ease off slightly, then fire up the grill for burgers, steaks, or grilled chicken with corn on the cob. A reliable instant-read meat thermometer takes the guesswork out of outdoor cooking, and a grill brush and scraper set will keep your grates summer-ready all season long. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Wednesday and Thursday stay near 111°F — that’s the peak of this heat event, per NWS forecasters. Some moisture pushes into the higher terrain mid-week, bringing isolated storms to the mountain areas. By Friday and into the weekend, drying conditions and increasing winds will raise fire danger across the region, so keep that in mind for any outdoor or open-flame plans.
Looking further ahead, the Arizona Diamondbacks host the San Francisco Giants at Chase Field on June 29 — arguably the best air-conditioned venue in the Valley for beating the heat while catching a ballgame. Get tickets on SeatGeek and grab Official team gear on Fanatics before the series opens. Stay current all week with the Phoenix weather forecast, and check outdoor gear deals to make sure you’re set for whatever the desert delivers next.
