Expert opinion

A northerly and mostly variable flow prevails over the South-East of the basin. Over the West and the North, it is southerly, strong and mostly variable.

For Plage de la Base Nautique :
No gale warning.

We are 90% sure of the situation, because flows might be far more disturbed than forecast.

Overcast with reduced visibility in the morning, very cloudy skies to overcast in the afternoon. The risk of seeing rain will remain low. In the evening, cloudy and humid with a risk of fog.
No precipitation. ENE force 3 in the morning turning ESE force 2 in the middle of the day. Gusts reaching 13 knots in the morning. Slight sea. Low, fairly long swell from WSW. Visibility reduced by mist temporarily in the middle of the day.
