For Château d"Oléron :
No gale warning.
We are 85% sure of the situation, because in this type of situation, it is difficult to define precisely when the precipitation will end.
Very cloudy. But clear spells will become more and more widespread. Light showers progressively dying out in the morning, possibility of showers in the afternoon. In the evening, good clear periods but lots of cloud, too.
Chance of light rain. S force 3 turning W force 2 in the middle of the day then NNE force 3. Gusts reaching 15 knots in the morning. Smooth to slight sea becoming smooth in the evening. Low, short swell from W. Poor visibility temporarily in the middle of the day.
