Expert opinion

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

For Les Grands Sables :

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

Overcast skies. Rain remaining light. In the evening, overcast skies.
Rain followed by showers. SSE force 5 in the morning turning SSW force 4 in the evening. Gusts reaching 29 knots in the morning. Slight sea. Low, long swell from W. Poor visibility becoming good in the middle of the day then excellent.
