The Météo-France Public Data Portal (donneespubliques.meteofrance.fr) is the official open data portal operated by Météo-France, France's national meteorological and climatological service. The portal provides public access to a wide range of meteorological and climatological datasets produced by Météo-France in the course of its public service missions. In late 2023, Météo-France migrated its open data offering to a new platform, meteo.data.gouv.fr, which opened on 12 December 2023 and offers free and unrestricted access to all public meteorological data.
Météo-France was established as a public institution (établissement public) of the French state and serves as the national meteorological authority. Its public data portal was created to fulfill obligations under French law (Loi n°78-753 du 17 juillet 1978) regarding the reuse of public information. Prior to 2024, some datasets were subject to technical fees; from 2024 onward, in a move announced in November 2023, all public data became freely accessible and reusable. As of early 2026, the legacy portal at donneespubliques.meteofrance.fr was in the process of being decommissioned, with all content migrated to meteo.data.gouv.fr and the API portal at portail-api.meteofrance.fr.
The portal offers access to observation data from surface and upper-air stations, radar precipitation data, climatological archives dating back more than 150 years, numerical weather prediction model outputs (including AROME and ARPEGE), vertical profiling data from radiosonde balloons, and climate scenario projections. Daily, monthly, and climatological summary datasets are available, as well as specialist datasets such as forest fire weather monitoring and marine buoy observations.
The new open data platform (meteo.data.gouv.fr) provides free download and API access to all datasets. Users requiring high-volume data access or API integrations are directed to the API portal. Documentation and community support materials are available through the Confluence-hosted open data documentation site. The platform is used by researchers, climate scientists, developers, educators, journalists, and the general public.
