Expert opinion

A northerly, strong and mostly variable flow prevails over the West of the basin. Over the East, it is easterly, moderate and mostly variable.

For Plage de la Base Nautique :
Warning strong breeze offshore.

We are 90% sure of the situation, because the strength of the precipitation is difficult to assess for this type of disturbance.

Relatively clear skies becoming changeable. Light showers. In the evening, very cloudy skies becoming totally overcast.
Light, intermittent drizzle. NE wind force 3 from the middle of the day. Gusts reaching 17 knots in the evening. Slight sea. Low, fairly long swell from SW. Poor visibility becoming good in the evening.
