Florida Braces for Freezing Temperatures on December 31 as ‘Falling Iguana’ Risk Increases Across the State

FLORIDA — A sharp blast of cold air is expected to sweep across Florida on the final morning of 2025, bringing temperatures low enough to trigger a statewide Falling Iguana Alert. Forecast models show lows dipping into the 20s across northern Florida and the 40s and 50s across southern counties, creating conditions that commonly cause iguanas to freeze, lose mobility, and fall from trees.

Coldest Morning of the Season Expected Across the State

Meteorologists report that December 31 could be the coldest morning of the year for millions of Floridians. The latest data indicates:

• 20s across the Panhandle and inland northern regions
• 30s stretching through central Florida
• 40s and low 50s toward the southern half of the peninsula
• Low to mid 50s near coastal South Florida

While these temperatures are normal for many parts of the country, they are unusually cold for Florida and can create disruptive wildlife behavior and short-term hazards for residents.

Why Iguanas Fall During Florida Freezes

The “falling iguana” phenomenon—often joked about online—is in fact a real biological response. When temperatures drop into the 40–50°F range, iguanas become temporarily immobilized. Their bodies slow down, they lose muscle function, and many fall from trees where they typically sleep.

Experts emphasize:

• The iguanas are not dead, only stunned.
• They usually recover once temperatures rise again.
• South Florida has a large iguana population, increasing the likelihood of sightings.

Residents are urged not to approach or attempt to warm the animals, as they can become alert suddenly and may react defensively.

Travel and Outdoor Impacts Expected on New Year’s Eve Morning

The cold blast arrives as year-end celebrations begin, meaning many Floridians and visitors could encounter:

• Frozen patches on bridges and elevated roads in northern areas
• Hazards from fallen iguanas near trees, sidewalks, and residential neighborhoods
• Unusually cold outdoor conditions for early New Year’s Eve events

Officials recommend dressing warmly, checking car batteries, and preparing pets for the colder weather.

Model Guidance Suggests Sharp but Short-Lived Cold Snap

While the last morning of 2025 will be significantly colder than average, the freeze is expected to be brief, with temperatures rebounding later in the day and into early January. Meteorologists continue to monitor the Arctic air mass responsible for the temperature plunge and will provide updates as models refine overnight lows.

For Floridians—especially those in iguana-heavy counties—the unusual weather serves as a reminder of the state’s dramatic climate swings and the importance of staying prepared for rare cold events.
