Forecasters are calling for temperatures to drop in South Florida right before New Year’s Eve next week, leading to a cool, maybe even nippy end to 2025.
The southern U.S. and Florida will be coming off a Christmas hot spell and descending into brisk weather.
“Gonna be quite the shock to the system, with 20s into North FL, 30s Central FL, and this one may actually reach far South FL with 40s! These are real temps. Wind chills will be lower,” wrote WFLA-TV chief meteorologist Jeff Berardelli on X.
A 180!
After a record hot Christmas across the Middle & parts of the South, a New Year’s Arctic Blast promises a Deep South Freeze by New Year’s Eve.

“Looks like there’s a cooldown coming to South Florida right before the new year,” said AccuWeather meteorologist Dan Pydynowski. “We’ll be on the tail end of a cold front coming southward across the FL peninsula.”
AccuWeather and Weather.com are predicting the cooldown to start on Tuesday, Dec. 30, with daytime highs at around 67 and overnight lows dipping to 52 in suburban Palm Beach County.
Apple Weather is calling for lower temperatures, suggesting overnight lows for Tuesday and New Year’s Eve to be as chilly as 43 to 45 in suburban Palm Beach County, 47 in Fort Lauderdale and 50 in Miami.
South Florida will still remain relatively protected from the cold air. For comparison, Gainesville could be as cold as 27 on the night of Tuesday, Dec. 30.
The cooldown will be caused by a dip in the jet stream. “We’re pretty far out, but a dip in the jet stream centered over the Midwest and Northeast means the core of the coldest air will be there,” Pydynowski said.
The chill will be tempered by the angle of the blast. This won’t be a straight north-to-south shot of cold air, said Pydynowski. “This will be more of a glancing blow … from the edge of a dip in the jet stream.”
The cooldown should only last two days, he said.
