Expert opinion

A northwesterly, very strong and variable flow prevails over the whole area.

For Les Grands Sables :
Warning fresh gale offshore.

We are 80% sure of the situation, because there is a doubt about strength of the wind.

Clear periods developing. Light rain followed by showers. In the evening, good clear periods but lots of cloud, too.
Possibility of showers NW wind force 6 from the middle of the day. Gusts reaching 42 knots in the middle of the day. Slight sea. Low, fairly long swell from S. Excellent visibility.
