Expert opinion

A southeasterly, strong and variable flow prevails over the West of the basin. Over the East, it is northwesterly, moderate and very variable.

For Plage des Grandes Vallées :
No gale warning.

We are 90% sure of the situation, because the high pressure system could move in more quickly than forecast.

Some fair-weather cumulus clouds. In the evening, changeable skies clouding over completely.
No precipitation. WSW force 4 in the middle of the day becoming W force 3 in the evening. Gusts reaching 21 knots in the middle of the day. Slight sea. Low, fairly long swell from WSW. Good visibility becoming reduced by mist in the evening.
