Miami wakes up Saturday to partly cloudy skies, temperatures around 82 degrees and a stiff southeast breeze. The day will turn sunny and hot, with a high near 89 and a heat index that could reach 105. Rain should stay limited around the city, though the interior and southwest parts of South Florida face better odds for afternoon storms.

The National Weather Service Miami office expects southeast winds around 13 mph today, with gusts potentially making exposed areas feel breezier. Forecasters are calling for a moderate heat risk across eastern South Florida, so outdoor plans will be more comfortable earlier in the day or near the water.

Storm Chances Rise After Dark

Tonight will stay warm, with a low near 83 and heat index values still reaching about 101. A 30% chance of showers and thunderstorms is forecast from roughly 8 p.m. through early Saturday morning, with the best chances arriving inland rather than along the immediate Miami coast.

Sunday Brings More Heat

Sunday starts with a slight chance of showers and thunderstorms before 1 p.m., followed by mostly sunny skies and another high near 89. The heat index could climb as high as 106, while east winds around 13 mph may gust to 18 mph.

The pattern stays mostly sunny from Monday through Thursday, with highs between 89 and 91 degrees and overnight lows in the low 80s. A plume of Saharan dust may approach South Florida around midweek, which could make the air drier and suppress some storm activity, but the heat will remain the main concern.

Rip Current Risk Remains Elevated

Anyone heading north to Broward or Palm Beach beaches should use extra caution: the National Weather Service says a high risk of rip currents will continue through this evening. Swimmers should stay near lifeguards, avoid entering the water alone and leave immediately if thunderstorms move into the area.
