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 Les Grands Sables :
No gale warning.

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

In the evening, fair weather with mostly clear skies.
W wind force 2. Gusts reaching 9 knots in the evening. Smooth to slight sea. Low, fairly long swell from NW. Good visibility.
