Expert opinion

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

For Grande Plage :
Warning moderate gale offshore.

We are 90% sure of the situation, because the atmosphere might be less unstable and showers more frequent than forecast.

Skies changeable to very cloudy. Risk of showers in the morning, possibility of a few spots in the afternoon. In the evening, overcast skies.
Light rain. S force 5 in the morning becoming force 4 in the evening. Gusts reaching 33 knots in the middle of the day. Smooth to slight sea becoming slight in the evening. Low, long swell from SSW. Excellent visibility.
