By midday Saturday, June 27, Phoenix is lounging in the mid-80s under clear, bone-dry skies, but that comfort window will not last long. Forecasters expect the heat to surge to around 106°F this afternoon, with gusty south-southwest winds ramping up later in the day. Those winds, paired with humidity in the single digits to low teens in spots, will crank up the risk for blowing dust and elevated to critical fire weather through Sunday. If you have outdoor plans, aim for the morning and tie down anything in the yard that might go flying once the breeze kicks in.
Afternoon Winds Take Center Stage
South-southwest winds are on track to strengthen this afternoon, with sustained speeds of about 10 to 20 mph and gusts commonly reaching up to 25 mph across metro Phoenix, according to the National Weather Service. Farther west and along the Lower Colorado River Valley, the wind machine turns up a notch, with widespread gusts of 25 to 35 mph and locally higher bursts. The strongest pockets could hit 50 to 55 mph in the most exposed desert areas. That kind of wind is more than enough to kick up dust and make driving a handful, especially for high-profile vehicles and evening commuters.
Heat Timeline: Up, Down, Then Up Again
Saturday tops out near 106°F, and overnight temperatures only back off into the upper 70s to low 80s, so it will not feel especially cool after dark. Sunday offers a modest break, with highs closer to 102°F, and early next week brings a brief step down into the upper 90s to low 100s before temperatures trend warmer again later in the week. Even with that short-lived cooldown, heat stress remains a concern. Keep water handy and steer clear of heavy exertion during the peak afternoon hours.
Cooling Help Around The Valley
The City of Phoenix and Maricopa County run a Heat Relief Network with cooling centers, hydration stations, and a downtown 24/7 respite location. You can call 2-1-1 or visit the city’s Heat Relief pages at City of Phoenix for locations and hours. If you rely on transit or need help getting to a site, 2-1-1 can connect you with transportation options and referrals. Anyone with health concerns should get to shade, drink water, and seek medical help if they start feeling dizzy, faint, or unusually weak.
Big Takeaways For The Weekend
Through Sunday, the main troublemakers will be gusty south-southwest winds, areas of blowing dust, and higher fire danger. Keep outdoor chores to the morning, secure patio furniture, and avoid driving into dust clouds. If visibility suddenly drops, pull well off the road, turn off your lights, and wait it out. Stay tuned to updated forecasts and local advisories over the next 48 hours, especially if you live near river valleys or along the Lower Colorado corridor.
