By Monday afternoon, Miami’s forecast calls for a high near 90, with showers and thunderstorms possible later in the day. The National Weather Service’s Miami forecast gives the expected conditions.
Showers Could Arrive Monday Afternoon
The latest forecast puts the chance of showers and thunderstorms at 20%, mainly between 4 and 5 p.m. Any activity is expected to be isolated or scattered, with widespread rainfall totals below a quarter inch. The Miami point forecast gives the timing and probability, while the NWS Miami forecast discussion says widespread totals should remain under a quarter inch.
A coastal flood statement is in effect through 8 p.m. for far South Miami-Dade, including the risk of minor flooding around high tide. The NWS Miami-Dade alert page lists the affected areas and statement timing.
Tuesday Brings Sunshine And A Drier Feel
Monday night will dip to around 78 degrees before Tuesday turns sunny, with a high near 87. Northeast winds are forecast at 10 to 13 mph, with gusts as high as 18 mph. Drier air behind the weak front should make Tuesday feel less humid, even though temperatures remain warm. The NWS Miami forecast gives the Tuesday temperature and wind details; the forecast discussion describes the drier air arriving.
Monday’s forecast calls for a high near 90, while a weak front is expected to bring drier air on Tuesday.
Anyone spending a long stretch outdoors Monday should plan for shade, water and breaks from the heat.
The afternoon heat index is a measure of how temperature and humidity combine to affect how hot it feels—not a forecast of the air temperature itself. The National Weather Service notes that the index assumes shady conditions with light winds; exposure to full sunshine can raise the heat experienced by as much as 15 degrees, making shade especially important during outdoor activity. NWS heat-index guidance explains the distinction.
Rain Chances Return Midweek
Wednesday is now forecast to be sunny with a high near 87, rather than carrying a slight chance of showers and thunderstorms. The drier spell is expected to fade as moisture returns later in the workweek, bringing renewed rain possibilities across South Florida. The Miami point forecast gives Wednesday’s outlook, and the NWS forecast discussion describes the moisture returning Wednesday into Thursday.
The weekend forecast remains uncertain as a frontal boundary could affect South Florida; rain chances could be higher than normal if it stalls.
