South Florida is heading into New Year's Eve and New Year's Day under chilly conditions after a cold front pushed through the region Tuesday morning, setting the stage for some of the coldest temperatures of the season.

Temperatures dipped to 66 degrees early Tuesday, but that mild start will be short-lived. 

The NEXT Weather team expects readings to fall steadily through the evening, dropping into the 50s before midnight, with the coldest wind chills arriving overnight and into early Wednesday. Inland areas could feel like the upper 30s, with overnight lows around 50 degrees.

Cold air advisory and wind chills for parts of South Florida

A cold air advisory is in effect for inland Palm Beach and Collier counties. The advisory replaces the former wind chill advisory and is issued when temperatures or wind chills drop below 35 degrees. 

Thousands of South Florida visitors are fleeing the cold, looking for warm sun. 

"We flew out of Kansas City, and it was negative one with the wind chill. So it's pretty nice down here," said Broc Haskell. Like most people on the beach, Haskell isn't phased by a forecast of temperatures in the 40s when waking up on Wednesday.

"That's kind of a beautiful day for Kansas. Would be in the 40s this time of year, so we'll be good with it,: he said 

The National Weather Service said cooler-than-forecast temperatures could lead to the advisory being extended into inland Broward County, though metro areas are unlikely to see conditions meet advisory criteria.

"The colder it is up north, the more people we'll have down here," said Keith Arvay. He works at Rocco's Pizza and said the only downside is the breakfast rush when dining Alfresco is just frio. 

"The only thing that really affects is the early morning breakfast from like seven till nine, and once it warms up, we're good," he said.

Chilly weather will continue through New Year's Eve, with temperatures again falling into the 50s by midnight. 

By New Year's morning, lows are expected to dip into the upper 40s, though winds will be lighter compared to earlier in the week.

Cold conditions linger into the start of 2026, but a warming trend is expected to begin Thursday night, with temperatures gradually climbing back toward seasonal averages by the end of the week.
