Open the live Fresno map →What you'll see on the Fresno map
Temperature, humidity, wind and pressure from Fresno-area airports, PM2.5 and AQI from official EPA AirNow and reference monitors, plus backyard stations run by locals. Overlays add live rain radar, NWS warnings, wildfire and smoke, and real-time lightning. Every pin shows its source and how fresh the reading is — and Fresno could use its first community sensor (that could be you).
