| Date | Title, description |
| 01.10.2026 | Drought situation
The winter of 2025/26, which saw little snow, and the various heatwaves of the summer of 2026 led to an acute drought, which left its mark on the landscape and caused streams and springs to dry up.
Current precipitation deficits for the period 1 October 2025 – 30 September 2026:
- Grimsel Hospiz (1980m) = 460mm / 27.1%
- Napf (1406m) = 490mm / 32.4%
- Koppigen (486m) = 327mm / 31.8%
Basis: Climate norm values 1991–2020, measurement data from MeteoSchweiz.
A few minor rainfall events will not be enough to make up for these deficits. |
