Tequesta and South Florida Deal with Cold-Stunned Iguanas as Winter Arrives

Tequesta and communities across South Florida are managing a seasonal phenomenon that has become increasingly familiar in recent years—the appearance of cold-stunned iguanas during winter cold snaps. As temperatures plummet, these large reptiles become lethargic and immobile, falling from trees and clustering in unusual places throughout neighborhoods and public spaces. Local authorities have responded to the situation, implementing strategies to address the presence of these displaced animals across the region.

For Tequesta residents, this seasonal challenge presents both a safety and wildlife management concern. Residents may encounter iguanas in their yards, on sidewalks, or in other unexpected locations during freezing periods. The influx is temporary—as temperatures warm, the iguanas regain mobility and return to their normal behavior. Understanding what's happening and how to respond if you encounter a cold-stunned iguana can help residents stay safe and avoid unnecessary injury to themselves or the animals.

This phenomenon has become a recurring winter event throughout South Florida due to the region's unique climate and the establishment of an iguana population that struggles with extended periods of cold. Iguanas are native to Central and South America and Central America, where they thrive in warm tropical environments. When temperatures in South Florida drop below 50 degrees Fahrenheit, their metabolism slows dramatically, and they become unable to move or regulate body temperature effectively. This ecological dynamic has created a seasonal management issue that authorities across the region have had to address repeatedly.

For locals, the practical takeaway is straightforward: avoid handling cold-stunned iguanas you encounter, as they may bite if moved or disturbed. Keep pets indoors and away from affected areas, and report large concentrations of iguanas to local wildlife authorities if you're concerned about safety in your neighborhood. While the situation can seem alarming, it's temporary and typically resolves as weather warms.

This seasonal influx reflects a broader environmental reality in South Florida—the region's warming climate patterns over decades have allowed non-native species to establish themselves, but the area's still-occasional winter freezes create these dramatic management scenarios. For Tequesta and the broader South Florida community, managing this balance between climate adaptation, wildlife safety, and ecological stewardship remains an ongoing local conversation.
