Phoenix is sunny and dangerously hot today, with a high near 110°F and heat index values up to 112°F under an Extreme Heat Warning that runs through this evening — the National Weather Service says push outdoor plans to early morning or head somewhere with A/C.
Today’s Setup
An unseasonably strong subtropical high parked near the Four Corners is driving this heat, with atmospheric heights the NWS says rank above the 98th percentile for early August. That ridge is finally nudging eastward, easing highs a couple degrees off Saturday’s peak, but 108-112°F is still brutal from Ahwatukee to Arcadia, and lows only dip to around 89°F overnight.
Best Window To Be Outside
If you’re hitting South Mountain, Camelback, or a morning loop through Papago Park, be off the trail by 8 a.m. Pavement and rock surfaces turn into ovens fast once the sun’s up. Save anything active for right around sunset.
Rain, Wind, Dust, Or Heat Risk
Heat is the main threat this weekend, not storms — the NWS notes shower and thunderstorm activity is mostly confined to higher terrain. Lower-desert neighborhoods could still see gusty outflow winds and patchy blowing dust between about 7 and 9 p.m. tonight, followed by a slight chance of storms overnight. If a dust wall approaches while driving, pull off the road and wait it out. Monday brings real change: deeper monsoon moisture arrives, with showers and thunderstorms likely after 5 p.m., a 60% chance of rain, up to half an inch possible, and a cooler high near 107°F.
What To Wear Or Bring
Lightweight, breathable layers matter more than anything else today — moisture wicking undershirts men’s styles help a lot in this heat, paired with a wide-brim or UPF-rated hat. There’s also a UPF 50+ Sun Hoodie deal for just $5 worth grabbing before your next hike, plus more picks in our outdoor gear deals.
Tonight’s Games And Shows
The Arizona Diamondbacks host the Los Angeles Dodgers at Chase Field today — the retractable roof keeps gameday comfortable no matter how hot it is outside, so get tickets on SeatGeek and grab official team gear on Fanatics before first pitch. Headed to John Mellencamp’s Dancing Words Tour tonight at Talking Stick Resort Amphitheatre? That’s an open-air venue, so bring water — find tickets on StubHub if you still need seats. Looking ahead, check our Lionel Richie and Earth, Wind & Fire preview before their Tuesday, Aug. 11 show at Mortgage Matchup Center (a Lionel Richie t-shirt makes a nice pickup), and our Santana and Doobie Brothers coverage ahead of their Oneness Tour stop there Friday, Aug. 14 — a Santana t-shirt is a solid souvenir.
Dinner Tonight
With triple-digit heat lingering into the evening, keep the kitchen simple — a quick stir-fry or pasta dish beats firing up the oven and adding more heat to the house. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door, with Amazon Fresh groceries making it easy to stock up without stepping into the sun.
Next Few Days
Monday should bring the first real break from this weekend’s Extreme Heat Warning, with highs easing to 107°F and better rain chances spreading into the lower deserts as deeper monsoon moisture takes over.
