Florida – A crisp breeze slips off Biscayne Bay this morning, rattling palm fronds and surprising early risers with jacket weather. Thermometers hover near 50 degrees, a rare chill for Miami, as the final morning of 2025 begins cooler than many expected.
According to the National Weather Service, dry air and northwest winds ushered in the coolest air mass of the season across South Florida. Winds gust near 20 mph at times, keeping wind chills in the upper 40s early. Skies stay clear, allowing sunshine to work quickly by late morning.
Across Miami, Hialeah, Kendall, and Miami Beach, the cool start eases fast. Highs climb into the mid-60s this afternoon, making outdoor errands comfortable but breezy. Drivers may notice stronger crosswinds on the MacArthur Causeway, I-195, and exposed east-west roads near the coast.
New Year’s Day brings a noticeable shift. Sunshine dominates, and highs rebound into the upper 60s, then low 70s by Friday. Mornings stay mild, with lows in the 50s, ending any concern for cold-sensitive plants or outdoor plans.
By the first weekend of 2026, South Florida feels like itself again. Saturday turns sunny and warm with highs near 75. Beach conditions improve, though a light onshore breeze continues. Sunday trends warmer still, reaching the upper 70s with only a slight chance of brief showers late.
For now, enjoy the cool relief while it lasts. Dress in layers early, then plan for sunglasses by afternoon. South Florida’s winter cameo is short-lived. Did the cool air catch you off guard this morning?
