OpenWeatherMap

OpenWeather (operating openweathermap.org) is a global weather data platform delivering current weather, multi-horizon forecasts, historical archives, climate statistics, air pollution, solar irradiance, road risk, geocoding, and weather map tiles. Data is sourced from satellites, weather models, radars, and a worldwide network of weather stations, served through REST APIs across a freemium, multi-tier, and pay-per-call commercial model.
