Expert opinion

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

For Plage des Mouettes :
No gale warning.

We are 90% sure of the situation, because, given the current situation, the size of the cloud cover is difficult to assess.

Fairly cloudless skies becoming changeable during the morning, increasing sunny spells in the afternoon. No precipitation. In the evening, skies with few clouds.
SSE force 3 turning SSW in the middle of the day then WSW force 2. Gusts reaching 13 knots in the middle of the day. Slight sea. Low, fairly long swell from WSW. Poor visibility becoming excellent in the middle of the day then good.
