Miami wakes up warm and sticky on Saturday, Feb. 21, 2026, with mostly clear skies, muggy air and temperatures in the upper 60s. By afternoon, highs climb into the upper 70s to near 80°F under mostly sunny skies and a light southeast breeze. The quiet stretch will not last long, though, as a cold front pushes through Sunday afternoon into Sunday evening, bringing around a 30% chance of showers and ushering in much cooler, drier air early next week.
Foggy Mornings, Sunny Afternoons
Before sunrise, patchy to locally dense fog is likely across interior neighborhoods and parts of Southwest Florida, with visibility dropping to a quarter mile or less in spots. Most of the gloom should burn off shortly after sunrise, but predawn drivers should allow extra time, use low beams and slow down if they run into thick fog. According to the National Weather Service Miami, fog is expected to redevelop late tonight into early Sunday over interior areas.
Sunday Front Brings Showers and Cooler Air
The cold front moves in Sunday afternoon into the evening, increasing the chance of spotty showers after about 1 p.m., particularly over local waters and near Lake Okeechobee. Once the front passes, winds shift to the northwest and turn breezy, with sustained speeds around 15 to 22 mph and gusts pushing into the upper 20s. Behind it, highs only make it into the 60s on Monday, while some interior spots could see lows dipping into the 30s early next week. If you have outdoor plans Sunday evening, it is worth having a backup indoor option in case those late-afternoon showers pop up.
Beaches And Fire Weather
Along the Atlantic beaches, the rip current threat is elevated today, with a high risk for the Palm Beaches and a moderate risk along much of the rest of the Atlantic coast. Seas will run around 2 to 3 feet. Boaters should use caution, and swimmers should stick to lifeguarded areas and follow posted flags, especially late Sunday into early next week as winds and seas build behind the front.
The region is also dealing with a notable drought that is setting the stage for dry, breezy conditions and an elevated fire-weather threat early next week, and local officials are urging water conservation. As reported by Axios Miami, groundwater levels and the Biscayne Aquifer remain low, and voluntary conservation is currently advised.
