What is a PWS?
Personal Weather Stations (PWS) are individually-owned outdoor instruments that measure weather conditions. Basic stations may include a thermometer, barometer, anemometer, hygrometer, and wind vanes. More sophisticated stations may also measure UV index, leaf wetness, soil moisture and temperature, and water temperature. Weather Underground’s network collects real-time data from these personal weather stations, offering hyper-local weather data and webcams.  Learn More >
