Miami is starting Sunday with mostly clear skies and temperatures in the mid-80s, but the comfortable part of the day will be brief. A Heat Advisory takes effect late Sunday morning as humidity pushes feels-like temperatures above 105 degrees across the metro area.
The advisory runs from 11 a.m. to 6 p.m. Sunday, according to the National Weather Service. Miami should reach a high near 89 degrees, with east winds around 13 mph and gusts up to 18 mph. A slight chance of showers and thunderstorms is in the forecast between 8 a.m. and 5 p.m., but most of the day should remain sunny.
Heat Peaks Before Evening
Temperatures will climb from about 85 degrees early Sunday to the upper 80s during the afternoon, when the combination of heat and humidity will be most uncomfortable. Sunday night will stay unusually warm, with a low near 84 and heat-index values still reaching about 101.
Storm coverage should be more scattered across inland areas and Southwest Florida, meaning Miami may avoid the worst of the afternoon downpours. Along the Atlantic beaches, persistent easterly winds are keeping rip-current risk elevated, so swimmers and beachgoers should take posted warnings seriously.
Hot, Mostly Sunny Stretch Ahead
Monday will be sunny with a high near 90 and a heat index as high as 106. Tuesday and Wednesday should also reach around 90 under mostly sunny skies, while Thursday could be the warmest day of the stretch at about 91 degrees.
Rain chances rise again late in the week as more tropical moisture moves in. Friday brings a slight chance of showers and thunderstorms after 2 p.m., followed by another slight chance Saturday. Residents should drink plenty of fluids, seek air conditioning or shade, wear lightweight clothing and limit strenuous outdoor activity during the hottest hours.
