South Florida residents are gearing up for another classic summer day as a Heat Advisory takes effect across Miami-Dade and Broward counties from 11 a.m. to 6 p.m. on Friday, August 21, 2026. Forecasters are reminding locals to stay hydrated, seek shade, and check on neighbors and loved ones during the hottest hours of the day.
Temperatures are expected to climb into the low 90s, but with the region’s signature humidity, heat index values could make it feel significantly hotter — potentially reaching dangerous levels for those spending extended time outdoors. Meteorologists at WSVN 7News are encouraging residents to plan outdoor activities for the early morning or evening hours when conditions are more manageable. Cooling centers remain open throughout both counties for anyone who needs a break from the heat.
As is typical for South Florida summers, afternoon and evening storms are also in the forecast. Residents can expect the familiar pattern of sunshine giving way to scattered thunderstorms as sea breezes collide over the peninsula. While these storms can bring welcome relief from the heat, they also serve as a reminder to stay weather-aware, especially for those near open water or on the golf course during afternoon hours. Keeping a close eye on local radar apps is always a smart move this time of year.
The good news? This weather pattern is entirely normal for August in South Florida, and meteorologists note that conditions are consistent with historical climate norms for the region. Residents who are new to the area are encouraged to embrace the rhythm of summer — morning sunshine, afternoon storms, and warm evenings are all part of the unique South Florida lifestyle.
