Real-Time & Historical World Weather Data API
API keyHTTPSCORS ?
Weather
46 APIs
Weather APIs return current conditions, forecasts, historical data, air quality and UV levels for a location. Compare forecast resolution, how many days ahead are covered, whether historical data costs extra and how many calls the free tier allows. National weather services publish good data for free, but each one covers its own country best.
Open-Meteo needs no key and supports browser requests, and wttr.in serves forecasts as plain text or JSON. OpenWeatherMap, WeatherAPI and Visual Crossing require a key. Meteorologisk Institutt, Norway's weather service, asks only for an identifying User-Agent header, and US Weather is the US National Weather Service API.
