MET Norway Locationforecast

Worldwide hourly weather forecast from the Norwegian Meteorological Institute, no key required.

MET Norway publishes its global forecast model as a free JSON API: give a latitude and longitude, get temperature, wind, precipitation, humidity and symbol codes hour by hour for the next nine days. No key, no account. Their terms require a real identifying User-Agent and respect for the Expires header (do not refetch before it expires). A solid keyless worldwide alternative to Open-Meteo.
