Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
The Lac de Joux lies at 1004 metres in the Jura, and the canton of Vaud only allows kitesurfing on the middle part, between the line from Le Rocheray to Bas des Bioux and the line near L'Abbaye. Windulu places the spot at Les Bioux, within that stretch. The shore faces north, so north is onshore and north-east and north-west come in side-on, while east and west blow cross-shore along the narrow lake and south-east and south-west already come side-off the land. In a southerly you are blown towards the far shore, about a kilometre away, and then Windulu gives a warning instead of a no-go. Tide plays no part, and kitesurfing is only allowed from 8 am to 9 pm, so outside those hours Windulu gives a no-go. The live data comes every ten minutes, gusts included, from MeteoSwiss at Les Charbonnières, 6 kilometres to the north-east.
On the Lac de Joux kitesurfing is only allowed on the middle part, between the Le Rocheray-Bas des Bioux line and the Lionne (L'Abbaye)-Le Séchey line, not within 100 m of harbours and landing stages, and 200 m from passenger boats. Only from 8 am to 9 pm. Source: Canton de Vaud, RKite (BLV 747.23.5) art. 2 para. 3.
The open water at Lac de Joux (Les Bioux) faces NNW (348°). The safest wind directions to get on the water here are north, northeast and northwest (onshore or cross-onshore). With the wind from the east, southeast, south, southwest and west, it runs cross to cross-offshore: doable, but mind your position and don't go alone.
