Miami woke up Thursday, May 21, to clear skies and air already hovering around 81°F at Miami International Airport, and that sticky setup is not going anywhere fast. Expect a sunny, breezy day with highs near 86°F and overnight lows holding in the low 80s. Persistent east winds will keep the Atlantic choppy and make it feel hotter than the thermometer lets on.
Beaches And Rip Currents
Atlantic beaches along coastal Broward and coastal Miami-Dade are under a High Rip Current Risk through this evening, so lifeguards are pushing a simple message: swim only at guarded beaches and obey the flags. According to NWS Miami, rip currents can yank even strong swimmers away from shore. If you are caught in one, the advice is to float and signal for help rather than trying to fight the current.
Afternoon Heat And Winds
This afternoon stays sunny and breezy, with east winds around 10 to 15 mph and gusts up to roughly 18 mph along the shoreline. Heat indices will climb into the upper 90s across many neighborhoods and could reach triple digits in parts of southwest Florida, so it is a good day to stay hydrated, dodge strenuous outdoor activity during the peak heat, and check on neighbors who might be more vulnerable.
What To Expect Through The Holiday
Each day brings a slight chance of isolated afternoon showers or pop-up storms, mainly inland, and any storm that does bubble up could deliver brief heavy rain and gusty winds. Memorial Day is shaping up similarly, mostly sunny with a small risk of a passing afternoon shower and highs near the upper 80s, so planning beach time around lifeguarded hours is still the smart move. For background on the recent onshore flow and rough surf, see how rip currents roared earlier this month.
