General information
Welcome to MeteoSwiss' Open Data documentation.
Starting in May 2025, MeteoSwiss is gradually making its data accessible as Open Government Data (OGD). The available data can either be downloaded manually or obtained automatically as files.
MeteoSwiss is also working to enable access to certain data through individual API queries. However, this option will not be available before 2026.
Public Beta - April/May 2025
We are currently setting up our service as Beta.
During this phase everything is subject to change without prior notice.
Everyone can access the available Open Data already via geo.admin.ch's STAC API. Read the terms and conditions for using the infrastructure.
The access URLs are provided in the documentation for the corresponding datasets/collections:
