Expert opinion

A northeasterly and very variable flow prevails over the South of the basin. Over the North, it is southwesterly, strong and very variable.

For Plage de la Base Nautique :
No gale warning.

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

Little cloud in the morning, skies becoming progressively hazier during the afternoon. No precipitation. In the evening, hazy skies.
No precipitation. NE force 2 turning WNW force 3 in the middle of the day then NW. Gusts reaching 13 knots in the middle of the day. Slight sea. Low, fairly long swell from W. Poor visibility becoming excellent in the middle of the day then good.
