The warm, humid climate of central Florida provides ideal habitat for the eastern coral snake year round. Average temperatures range from the 60s°F (15-20°C) in winter to over 80°F (27°C) in summer. Rainfall averages 50+ inches annually, with peak precipitation in June through September.
This subtropical environment supports dense vegetation like palmetto scrub, pine flatwoods, swamps, and hammocks. Leaf litter, decaying logs, and loose sandy soils provide ample shelter. The abundance of small reptiles, amphibians, and rodents also supplies coral snakes with prey.
Developed areas adjacent to wildlands like parks and nature preserves harbor coral snake populations close to human habitation. Range expansion is occurring as this habitat generalist adapts to disturbed areas. Climate change may also enable coral snakes to expand northward.
