Expert opinion

A southeasterly, very strong and mostly variable flow prevails over the North-East of the basin. Over the South-East, a southwesterly gale is raging at sea. Over the West, it is northwesterly and strong.

For Plage Saint-Jean :
No gale warning.

We are 75% sure of the situation, because the atmosphere might be less unstable and showers rarer than forecast.

In the evening, very cloudy.
Light showers. S wind force 4. Gusts reaching 19 knots in the evening. Slight sea. Low, fairly long swell from WSW. Excellent visibility.
