Expert opinion

A westerly, moderate and very variable flow prevails over the whole area.

For Plage de Tronoën :
Warning strong breeze offshore.

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

Good clear periods alternating with cloudy spells, sometimes more dense in the afternoon. No precipitation. In the evening, good clear periods but lots of cloud, too.
No precipitation. WNW force 4 becoming W force 3 in the middle of the day then SW force 4. Gusts reaching 21 knots in the evening. Moderate sea. Moderate, fairly long swell from W. Excellent visibility.
