Phoenix weather today is mostly sunny with a high near 89°F and light south winds at 0 to 5 mph—a beautiful late April day across the Valley of the Sun.
This is ideal weather for hitting the trails at Camelback Mountain or South Mountain Park before the brutal summer heat arrives in just a few weeks. The National Weather Service notes that we’re still in the “near normal” temperature window through midweek, so if you’ve been waiting for the perfect day to get outside, today’s it. Grab an insulated water jug (1 gallon) to stay hydrated during your hike—the desert sun is deceptive, and even at 89°F, you’ll lose fluids faster than you think.
If you’re heading to tonight’s events in Phoenix, you’re in luck. The Phoenix Mercury takes on the Japan National Team in a preseason matchup at Mortgage Matchup Center, and conditions will be pleasant for the drive. Indoor venues like the Mortgage Matchup Center are perfect for catching live entertainment—also on tap tonight is the “Dancing With The Stars: Live! - 2026 Tour” at Arizona Financial Theatre and “HEALTH x CARPENTER BRUT” at The Van Buren. You can grab Get tickets on SeatGeek or Find tickets on StubHub for any of these shows.
Spring allergies are ramping up with the seasonal pollen, so consider keeping Claritin non-drowsy allergy on hand if you’re sensitive. A HEPA air purifier can also help keep your home’s air clean while you enjoy the pleasant evening temperatures dropping to around 62°F overnight.
Thursday will warm slightly to near 90°F with mostly sunny skies, but here’s where it gets interesting: the National Weather Service is tracking a closed low-pressure system just south of us over northern Mexico. While rain chances remain low (only 5-10% in south-central Arizona, 15-25% in eastern higher terrain), upper-level moisture will increase cloud cover through Thursday. The system is expected to track just south of the Phoenix metro, so we’ll mostly stay dry.
By Friday, that system exits to the east, and temperatures will begin climbing into the low to mid-90s as upper-level ridging builds over the West Coast. This is your last comfortable window before the heat ramps up significantly going into the weekend.
Tonight’s a perfect evening for grilling. Fire up a portable propane grill and cook something simple—maybe some tri-tip or steaks. With the light winds and mild temps, you won’t overheat while cooking. If you need supplies, you can order groceries on Amazon and have everything delivered for tonight’s dinner.
Looking ahead: Thursday stays mostly sunny and warm (90°F), with Thursday night clearing to mostly clear skies and a low near 65°F. Friday marks the beginning of a warming trend as we head into the weekend. Enjoy the comfortable weather while it lasts!
