Update Tuesday, 31.03.2026
General: The pronounced northerly pressure surplus that is currently causing a northerly foehn – with widespread snowfall and high wind speeds along the main Alpine ridge – will ease from around midday on Friday. In its wake, a high-pressure system will build, bringing plenty of sunshine, but from Sunday onwards this is expected to lead to southwesterly winds, possibly developing into a southerly foehn. There is still a lot of snow in the Alps at the moment; however, given the strong solar radiation and the forecast temperatures, we expect usable thermals to develop from Friday, or by Saturday at the latest.
We are provisionally favouring Lenk im Simmental as the venue, as we expect light winds and plenty of sunshine there. It is not yet clear whether the forests will already be snow-free and dry by Friday, but for the remaining days we expect good conditions. The two airfields are closed on Friday and Sunday; for the other two days we are in contact with the responsible parties, who have assured us of their support.
Alternatives considered so far:
- Fribourg Pre-Alps: Significantly stronger winds on Sunday and Monday.
- Jura: More cloud on Saturday, significantly stronger winds on Sunday and Monday.
- Surselva: More cloud on Saturday, risk of foehn on Sunday and Monday.
We will take the final decision tomorrow, Wednesday at 20:00.
