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 a later stage, customised queries via API will also be possible.
| A Ground-based Measurements |
B Atmosphere Measurements |
C Climate Data |
D Radar Data |
E Forecast Data |
|---|
Note
In order to also provide access to the data via APIs in future, the necessary preparatory work is underway. As soon as an introduction date for this second type of access can be estimated, it will be communicated here.
Here [upcoming] you'll find information about data license and conditions for usage.
Here [upcoming] you'll find answers to the most frequently asked questions.
We continuously update these based on questions received.
Here you'll find information about data granularity, structure and update cycle, time stamps and time intervals as well as on column separators, decimal dividers and missing values.
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,
- please check Release Notes (upcoming) where swisstopo announces released changes that might affect your integration.
In the event of malfunctions at land-based stations,
- check for according messages of interruptions in data availability.
