When is mosquito season in Oklahoma?

Oklahoma's mosquito season runs from April through October. 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. Hot, dry stretches briefly knock numbers back before the next rain refills the breeding sites.

Where are mosquitoes worst in Oklahoma?

Within Oklahoma, the most consistent pressure tends to land around Oklahoma City, Tulsa, and Norman. Urban heat plus abundant standing water — storm drains, retention ponds, backyards — concentrates activity around these metros. 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 Oklahoma forecast works

MosquitoCast estimates Oklahoma'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 Oklahoma is directly comparable to anywhere else in the country.
