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

For Grande Plage :
No gale warning.

We are 90% sure of the situation, because the high pressure system could move in more quickly than forecast.
