Florida Braces for ‘Iguana Rain’ as Temperatures Plummet
Table of Contents
A rare meteorological phenomenon – falling iguanas – is anticipated across Florida over the next several nights as temperatures are forecast to dip below 40°F. The unusual event occurs when the cold-blooded reptiles become immobile and lose their grip, leading them to drop from trees.
The impending cold snap poses a unique challenge for the Sunshine State, known for its warm climate and thriving iguana population. While not harmful to humans, the sight of falling iguanas can be startling, and officials are preparing for potential impacts.
Understanding the Iguana Drop
Reptiles, including iguanas, are ectothermic, meaning they rely on external sources to regulate their body temperature. When temperatures fall significantly, their metabolic processes slow down, and they become lethargic. According to one expert, “This dramatic temperature change essentially paralyzes them, causing them to lose their ability to cling to branches.”
This loss of muscle control results in the iguanas falling to the ground. While they appear lifeless in the cold, they are often merely stunned and will revive as temperatures rise.
Geographic Impact and Timing
The most significant risk of “iguana rain” is expected in South Florida, where the invasive species is most prevalent. The National Weather Service predicts temperatures will fall below the critical 40°F threshold beginning Thursday evening and continuing through Saturday morning.
Areas particularly susceptible include Miami-Dade, Broward, and Palm Beach counties. Residents in these regions should be aware of the possibility of falling iguanas, especially when walking under trees.
What to Do If You Encounter a Cold-Stunned Iguana
Authorities advise against attempting to handle cold-stunned iguanas. While they may appear docile, they can still instinctively bite or scratch. Instead, residents are encouraged to report sightings to local wildlife authorities.

The Florida Fish and Wildlife Conservation Commission (FWC) has issued guidance emphasizing that iguanas are an invasive species and should not be relocated. The FWC website provides detailed information on responsible reporting and management of iguanas.
This unusual weather event serves as a stark reminder of the impact of climate change and the challenges faced by non-native species adapting to fluctuating temperatures. The potential for further cold snaps in Florida underscores the need for continued monitoring and proactive management strategies to mitigate the effects on both the environment and the public.
