Expert opinion

High 1037 hPa centered at 200 nautical miles in the South-West of Fastnet Rock (South-West Ireland) moving at 7 knots to the South-South-West.

For Plage de la Base Nautique :
No gale warning.

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

Good clear periods but cloud building. No precipitation. In the evening, very cloudy.
No precipitation. NW force 3 in the middle of the day becoming force 4 in the evening. Gusts reaching 19 knots in the evening. Slight sea. Low, long swell from WSW. Excellent visibility becoming poor in the evening.
