South Floridians will kick in the new year with some nighttime chilly weather, down in the 40s.
A strong cold front is forecast to drop temperatures into the 40s on Tuesday night and Wednesday night. The cold front is “originating from up in the Arctic, and it’s just very powerful and working its way down south,” said Will Redman, a meteorologist with the National Weather Service in Miami.
Daytime temperatures aren’t likely to go past the 70s. “Maximum temperatures during the day will run a good 5-10 degrees lower than temperatures over the past week as the front drops through,” the weather service said.
The plunge in low temps overnight could bring an “excessive cold risk,” the weather service warned. “Just be prepared to bundle up,” Redman said.
After a relatively warm Christmas, the final day of 2025 (New Year's Eve) will have a relatively cold start for South Florida standards. Even colder temperatures are currently forecast for daybreak on New Year's Day.

Some other parts of Florida could reach the 20s and 30s. “Persistent northerly winds Tuesday night could result in even cooler apparent temperatures overnight, ranging between the upper 20s and lower 30s across portions of the interior, including areas in Glades and Hendry,” the weather service said.
A gradual warming will begin Thursday, with high temperatures rising back to the mid- and upper-70s by the weekend.
