Expert opinion

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

For Plage de la Base Nautique :
No gale warning.

We are 85% sure of the situation, because the high pressure system could move in more quickly than forecast.
