Expert opinion

A northeasterly and moderate flow prevails over the South and the East of the basin. Over the North-West, it is southwesterly, moderate and mostly variable.

For Saint-Guénolé :
Warning strong breeze offshore.

We are 85% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will begin.

Clear skies. Light showers. In the evening, good clear periods but lots of cloud, too.
Light showers progressively becoming less frequent. W force 3 in the middle of the day turning NE in the evening. Gusts reaching 17 knots in the evening. Smooth to slight sea becoming slight in the evening. Low, fairly long swell from W. Excellent visibility.
