Clear skies and about 73°F greeted travelers at Phoenix Sky Harbor on Sunday morning, May 17, 2026, but the quiet start is not sticking around. Southerly winds are expected to ramp up this afternoon and evening, with highs in the mid 90s and enough gusts to make exposed roads feel like a bit of a rodeo.
Afternoon Winds Pick Up
South winds should increase to around 5 to 15 mph this afternoon, with gusts commonly between 20 and 30 mph and a few stronger bursts in wide open spots. The breeze is expected to strengthen late in the day, so it is a good time to tie down patio furniture, secure trash and recycling bins, and be ready for sudden crosswinds during the commute.
Fire And Wind Alerts
A Red Flag Warning is in effect Sunday, May 17, 2026, from 11 a.m. to 11 p.m. for southern Gila County and the Tonto National Forest, where southwest winds of 15 to 25 mph and relative humidity in the low teens will combine to create hazardous fire conditions. Wind Advisories are also posted for the Salton Sea and Imperial Valley this evening, with west winds of 20 to 30 mph and gusts up to 40 to 50 mph that could kick up blowing dust and make driving tricky. For full details, check the National Weather Service Red Flag Warning and the National Weather Service Wind Advisory.
Plan Ahead
Fire officials are urging residents to postpone any outdoor burning or brush clearing today and to double check that grills, power tools, and other equipment that could spark are stored safely. If you need a break from the heat while the winds howl, the City of Phoenix operates a 24/7 respite site downtown at 20 W. Jackson Street, and the county maintains additional cooling centers across the Valley.
