Florida Mosquito Forecast

Florida sits squarely in mosquito country. A warm, humid, high-rainfall climate and roughly 53" of annual rain give it very high pressure and one of the longest active seasons in the country — from March through November.

When is mosquito season in Florida?

Florida's mosquito season runs from March through November. Activity ramps up once overnight lows hold above about 50°F, and surges in the two to three days after rain, when fresh standing water triggers a new hatch. In the warmest stretches it barely lets up.

Where are mosquitoes worst in Florida?

Within Florida, the most consistent pressure tends to land around Jacksonville, Miami, and Tampa. Warm overnight lows and heavy humidity in and around these metros keep mosquitoes biting well past sundown. Anywhere near rivers, marshes, lakes, or recent flooding will read higher than the surrounding area — exactly the kind of local detail the live map above is built to show.

How the Florida forecast works

MosquitoCast estimates Florida's mosquito activity from live weather — temperature, humidity, wind, and recent rainfall — layered on the area's long-term rainfall climate, elevation, and terrain, and refreshed every day from NOAA's forecast data. It's the same model nationwide, so the reading for Florida is directly comparable to anywhere else in the country.
