Expert opinion

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

For Plage de la Grève Blanche :
No gale warning.

We are 80% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will end.

Very cloudy. Light showers progressively becoming less frequent. In the evening, skies clearing but continuing risk of storms.
Possibility of showers WSW wind force 4 from the middle of the day. Gusts reaching 24 knots in the evening. Slight sea. Low, fairly long swell from WNW. Excellent visibility.
