Expert opinion

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

For Grève Noire :
Warning strong breeze offshore.

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

In the evening, good clear periods but lots of cloud, too.
No precipitation. W wind force 3. Gusts reaching 16 knots in the evening. Smooth to slight sea. Low, short swell from NW. Excellent visibility.
