📜Rules

💨Wind

🔥 Thermal: Mostly Bise / Vaudaire / Joran; the day breezes (rebat, séchard) are light, the séchard never reaches the Haut-Lac. Usually from S, strongest around 20:00.

🌅 Morning wind: 'Morget': night land breeze from the shore towards the middle of the lake (Rolle - St-Sulpice), 3-4 Bft, until about 7-9 h, from N.

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.
