Expert opinion

A southeasterly, strong and mostly variable flow prevails over the North-East of the basin. Over the South and the West, it is westerly, very strong and variable.

For Plage du Rosais :
No gale warning.

We are 80% sure of the situation, because the atmosphere might be less unstable and showers more frequent than forecast.

In the evening, good clear periods but cloud building.
Light showers progressively becoming less frequent. WSW wind force 3. Gusts reaching 17 knots in the evening. Slight sea. Low, short swell from NW. Excellent visibility.
