Florida Mosquito Forecast

Florida stretches far enough north-to-south that its mosquito season isn't uniform. Areas near Miami warm earlier and stay active longer, while cooler conditions up around Tallahassee squeeze activity into the peak summer months. Pressure can run high wherever it is warm and wet, but local conditions, shown on the map above, decide any given day.

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. The season also shifts within the state, running earlier and longer toward Miami and shorter and later up around Tallahassee.

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.
