MeteoSwiss - Open Data

Welcome to MeteoSwiss' Open Data documentation.

From April 2025, MeteoSwiss will make its data freely available to the public as Open Government Data (OGD). The data can be downloaded as pre-processed files.

In order to also offer the option of accessing the data at a later stage using individual queries via APIs, the necessary preparatory work is underway. As soon as introduction dates for this second type of access can be estimated, they will be communicated here.

General Information

Terms of Use

Staying up to Date

For operational status, see Download API Status & Contact [upcoming]

geo.admin.ch's download service will not be subject to big breaking changes, because it adheres to the OGC STAC API standard. Our partner swisstopo continuously develops and improves it, so minor changes and bug fixes might change the behavior of the API. If you suspect your integration has broken due to changed behavior, check Release Notes where swisstopo announces released changes that might affect your integration.

In the event of malfunctions at ground-based stations, check for interruptions in data availability.
