Phoenix weather Sunday is shaping up to be partly sunny with a high near 96°F, making it an ideal day to get outside before the heat intensifies later in the week.
Sunday morning starts mild, with overnight lows around 73°F and mostly cloudy skies. By 6 AM, expect partly sunny conditions to develop, with southeast winds at 5 to 10 mph gusting as high as 20 mph. The National Weather Service notes that above-normal temperatures this weekend will briefly cool into a below-normal range early next week, so if you’re planning outdoor activities, Sunday is your sweet spot.
Perfect Timing for Outdoor Recreation
Golfers should head out early—the 96°F high and light winds are ideal conditions for a round. Check out our guide on best golf balls for high handicappers if you’re looking to upgrade your game. Early morning tee times at courses like Camelback Golf Club or courses near South Mountain Park will be most comfortable.
Fishermen also have a solid window. With minimal wind and clear skies, lakes and reservoirs around the Valley should fish well through midday. An instant-read meat thermometer and a Stanley quencher tumbler are great additions to your tackle box for a full day on the water.
Diamondbacks at Chase Field
If you’re heading to Chase Field, the Arizona Diamondbacks vs. Pittsburgh Pirates on May 6 will feature pleasant late-afternoon conditions—upper 80s by game time with light winds. Grab an Arizona Diamondbacks jersey or Arizona Diamondbacks fitted cap to show your support, and snag tickets on SeatGeek or Find tickets on StubHub while they last. Tailgating conditions will be excellent, so fire up a propane gas grill and set up a patio furniture set near the stadium lot.
Evening & Overnight
Sunday night turns partly cloudy with a low around 69°F. South-southeast winds will pick up to 5 to 15 mph with gusts as high as 25 mph—typical spring pattern. No rain is expected (only a 2% chance), so outdoor string lights and evening activities are all go.
Grilling Weather Ahead
With Sunday’s mild conditions and light winds, it’s the perfect day to fire up the grill. Burgers, steaks, or grilled chicken with corn on the cob are calling your name. Grab a grill brush and scraper set to prep, and use an instant-read meat thermometer to nail the doneness every time. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Looking Ahead
Monday cools to a high near 83°F with mostly cloudy skies—a noticeable drop that signals the pattern shift the National Weather Service forecasters mentioned. By mid-week, expect a rapid warming trend with above-normal temperatures returning. Enjoy Sunday while it lasts!
