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.
We start with the ground-based measurements, homogeneous data series and numerical weather forecasting model data. Additional datasets will be released in the following months.
We are also working to enable access to certain data through individual API queries. However, this option will not be available before 2026.
Available datasets from May 2025
