💨Wind
🔥 Thermal: Light thermal from Urfeld around midday (10-15 kn), strongest spring/autumn with NW-NE background wind; Föhn kills it. Usually from NNE, strongest around 17:00.
FoilFlow checks the thermal conditions every day (sun strength, wind aloft, Föhn, Bise and the lake's own pressure rules) and shows when it is likely.
Forecasts from several weather models (e.g. ICON, AROME, HARMONIE) and live measuring stations nearby are in the app.
