South Florida’s subtropical climate mirrors the green iguana’s native range almost perfectly. Average winter lows rarely dip below the mid-50s°F in coastal areas, and humidity stays high year-round. The combination of warm temperatures, abundant water infrastructure, and lush tropical landscaping creates a near-perfect green iguana habitat. Established populations are densest in Miami-Dade, Broward, Palm Beach, Monroe, and Lee counties.
However, warmer-than-average winters have allowed iguanas to push northward. Sightings are increasing in Martin, St. Lucie, and even parts of Hillsborough County. If your property sits near a canal or lake and features tropical plants, you are in potential iguana territory regardless of your exact location.
