Expert opinion

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

For Grand Crohot :
Warning strong breeze offshore.

We are 80% sure of the situation, because the high pressure system could move in more quickly than forecast.

Very cloudy skies with short clear spells. No precipitation. In the evening, very cloudy.
Risk of showers in the early hours. N force 3 becoming NNW force 4 in the middle of the day then force 5. Gusts reaching 28 knots in the evening. Moderate sea. Moderate, fairly long swell from WNW then low in the evening. Visibility reduced by mist becoming excellent in the middle of the day.
