Miami woke up on Wednesday, February 25, 2026, to a rare combo platter: clear skies, a brisk 48°F at Miami International Airport, sunshine on the way and a frost advisory hanging over parts of inland South Florida. By afternoon, coastal and metro spots are expected to rebound into the low 70s under mostly sunny skies with a light southeast breeze. Smoke from a wildfire burning in Big Cypress National Preserve is still expected to cause pockets of reduced visibility along I-75 and some inland roads, while a Frost Advisory remains in effect for Hendry, Glades and inland Collier counties until 8 a.m. Wednesday.
Smoke And Road Safety
The National Park Service reports that a wildfire south of I-75 has forced area closures and created smoky conditions that are cutting visibility along Alligator Alley and the Tamiami Trail. Current park alerts cover land south of I-75 and east of SR-29, and officials are urging drivers to slow down, switch to low-beam headlights and build extra time into their trips. Travelers should be ready for temporary closures or traffic slowdowns while crews continue efforts to contain the blaze.
Sunny Midweek, Showers By Weekend
According to forecasters at the National Weather Service in Miami, Wednesday will stay mostly sunny with a high near 72°F, then temperatures climb into the upper 70s on Thursday and around 80°F by Friday. A slight chance of showers returns late Thursday night, with rain and isolated thunderstorms becoming more likely from Saturday into Sunday. Southeast winds are expected to run light to moderate, around 3-12 mph, and marine conditions could turn choppy in and near any showers or storms.
Beaches And Fire Weather
Atlantic beaches remain prone to strong rip currents through Thursday evening, so swimmers are urged to stick to lifeguarded areas and follow posted flags and warnings. South Florida is still locked in a severe to extreme drought, and afternoon relative humidity is forecast to dip into the 30 to 40 percent range, a combination that supports enhanced fire behavior and can trap smoke near the surface in low-lying spots. Anyone with outdoor plans should skip open burning and stay alert for quick shifts in wind and visibility.
Legal Implications
Big Cypress National Preserve has closed portions of the park south of I-75 and east of SR-29, and entering those closed areas is prohibited while fire crews are at work and may be subject to enforcement. Residents and visitors are urged to honor the closures, monitor official park alerts and follow local instructions until authorities formally lift the restrictions.
