In a strange but recurring event, frozen iguanas falling from trees in Florida is something that often captures attention during colder weather. While it might seem alarming or even humorous, it’s a natural response to the sudden drop in temperatures for these cold-blooded reptiles.
Why Do Iguanas Fall From Trees?
Iguanas are cold-blooded, meaning they rely on external temperatures to regulate their body heat. When the temperature in Florida drops below 40°F (around 4°C), the iguanas’ bodies begin to slow down, and they can enter a temporary state of paralysis. Their muscles become too stiff to function properly, which can cause them to lose their grip on branches, resulting in them dropping from trees.
- Not Dead, Just “Frozen”: Despite appearing lifeless when they fall, most of these iguanas are not dead. They are in a dormant state, and once the weather warms up, they typically regain mobility and carry on as usual.
- Common in Florida Winters: This phenomenon is particularly common during cold snaps in Florida, where iguanas—an invasive species—thrive in the warmer climate. When a sudden cold front hits, residents often witness these iguanas “raining” from trees.
What Happens to the Iguanas?
- Temporary Paralysis: Iguanas can remain in this frozen-like state for hours until the temperature rises. Once it warms up, their body temperature will slowly rise, and they will begin to move again.
- Risk of Injury or Death: Although most iguanas survive, some may suffer injuries from falling from tall trees or become vulnerable to predators during their immobile state. Prolonged exposure to extreme cold can also result in death for some iguanas, particularly younger or weaker individuals.
Impact on the Environment:
Iguanas are not native to Florida, and their presence has become a problem for the local ecosystem. They can cause damage to infrastructure, native vegetation, and even prey on smaller species. So while the falling iguanas event draws attention, it’s a reminder of the challenges that invasive species like iguanas pose to the environment in Florida.

Public Reaction:
Every winter when this phenomenon occurs, social media lights up with photos and videos of stunned iguanas lying on the ground, leading to a mix of concern and amusement. Florida wildlife officials often remind residents not to interfere with the iguanas, as they will typically recover on their own once the temperatures rise.
While it’s certainly a strange sight, frozen iguanas falling from trees is just another unusual part of living in Florida’s unique climate!
