Expert opinion

A southwesterly, strong and very variable flow prevails over the whole area.

For Les Dunes :
Warning strong breeze offshore.

We are 85% sure of the situation, because the high pressure system could move in more quickly than forecast.

Mist and fog in the morning, very cloudy in the afternoon. No precipitation. In the evening, very cloudy.
No precipitation. WSW force 2 in the morning freshening force 4 in the middle of the day. Gusts reaching 23 knots in the evening. Smooth to slight sea becoming slight in the evening. Low, fairly long swell from WSW. Visibility reduced by fog becoming poor in the middle of the day then excellent.
