Statistiques de Vent de ADs/Doubles, moyennes sur Avril depuis 2006
This image shows how commonly and how strongly the wind blows from different directions over a normal April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by dark blue. It is based on 2160 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to ADs/Doubles, located 28 km away (17 miles). There are insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at ADs/Doubles blows from the ENE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at ADs/Doubles. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (1 days each April) and blows offshore just 3% of the time (1 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 3 days at ADs/Doubles
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
