Expert opinion

A northwesterly and very variable flow prevails over the whole area.

For Plage de Port Biren :
No gale warning.

We are 80% sure of the situation, because the high pressure system could move in more quickly than forecast.

Skies changeable to very cloudy. No precipitation in the morning, light showers in the afternoon. In the evening, very cloudy skies clearing completely.
Possibility of showers NW force 3 in the morning becoming NNW force 2 in the evening. Gusts reaching 21 knots in the middle of the day. Slight sea becoming smooth to slight in the evening. Low, fairly long swell from WSW. Excellent visibility becoming good in the evening.
