Phoenix is starting Tuesday morning clear and comfortable near 65°F, with a mostly sunny afternoon ahead and a high near 91°F — a near-perfect late-spring day in the Valley. If you’ve been waiting for a good day to get outside, today is it. Keep an eye on the Phoenix weather forecast for hourly updates.
Today’s Setup
The National Weather Service is forecasting mostly sunny skies, west winds at 0 to 10 mph, and afternoon humidity dropping below 15% across the metro. Some thin high clouds will drift over the Valley today, but they won’t cut into the sunshine much. Temperatures start near 65°F this morning — roughly 5 degrees warmer than recent days — and climb steadily toward the lower 90s by afternoon. Normal highs for mid-May are in the middle 90s, so we’re actually running a touch below average right now.
Best Window To Be Outside
Early morning is prime time. Camelback Mountain and South Mountain trails will be comfortable well before 9 AM, and it’s a great day for a round of golf — a golf ball gift set Titleist makes a solid excuse to tee it up early while winds are calm. The National Weather Service says afternoon breezes will build with gusts potentially reaching 15–25 mph by mid-afternoon, so plan your most active outdoor time before noon if you can.
Allergy & Sun Watch
No rain and no storms this week — the National Weather Service sees zero precipitation chance through the next several days. That said, low humidity combined with afternoon winds can stir up dust and pollen across desert neighborhoods. If your kids are sniffly heading out, kids allergy chewables Zyrtec before outdoor activities can help. UV intensity runs high in late May, and with humidity this low, sun protection matters even at 91°F. Right now you can grab UPF 50+ Fishing Shirts for $6.50 — a cheap, effective option for outdoor adventures.
Tonight’s Events
Two big events hit the Valley tonight. The Demi Lovato: It’s Not That Deep Tour takes the stage at Desert Diamond Arena, and the Phoenix Mercury tip off against the Toronto Tempo at Mortgage Matchup Center. Evening temperatures settle into the upper 60s — comfortable for parking lot hangs and post-event walks. Get tickets on SeatGeek if you still need them.
Looking ahead to Wednesday, May 20, the Arizona Diamondbacks host the San Francisco Giants at Chase Field. Grab your Arizona Diamondbacks jersey before game day — a 93°F afternoon is warm but very manageable for a ballpark outing.
Grill Night
With a low near 68°F tonight, the patio is calling. Fire up burgers, steaks, or grilled chicken with corn on the cob — this is textbook Phoenix grilling weather. A grill brush and scraper set keeps the grates clean between uses, and an instant-read meat thermometer takes all the guesswork out of doneness. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Wednesday warms to a sunny 93°F — right at Phoenix’s seasonal normal, per the National Weather Service. Dry conditions and seasonal afternoon breezes continue through the end of the week with no rain in sight. Temperatures climb gradually from there, so enjoy this comfortable stretch before triple digits arrive. Browse outdoor gear deals to get ready for the weekend.
