Expert opinion

A northeasterly and variable flow prevails over the South and the East of the basin. Over the North-West, it is southerly, weak and variable.

For Carnac :
No gale warning.

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

Fair weather with mostly clear skies. In the evening, skies with few clouds.
NNE wind force 3 continuing all day. Gusts reaching 18 knots in the evening. Smooth sea becoming smooth to slight in the middle of the day. Low, fairly long swell from SSW. Good visibility becoming excellent in the middle of the day.
