Expert opinion

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

For Mers-les-Bains :
Warning moderate gale offshore.

We are 90% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will begin.

In the evening, good clear periods but cloud building.
Chance of light rain. SSE wind force 5. Gusts reaching 32 knots in the evening. Smooth to slight sea. Low, fairly long swell from W. Excellent visibility.
