Since May 2025, MeteoSwiss has been gradually making its data accessible as Open Government Data (OGD). The available data can be obtained as files via the channels listed below.
As soon as we can estimate a date from which further data will be available, we will announce it below.
We are also working to enable access to certain data through individual API queries. However, this option will not be available before the second quarter of 2026.
