Anse de Cabestan Wind Statistics, Autumn averages since 2006
The figure illustrates how commonly and how strongly the wind blows from different directions over a normal northern hemisphere autumn. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 7252 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anse de Cabestan, located 11 km away (7 miles). There are too few 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 most common wind at Anse de Cabestan blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Anse de Cabestan. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (7 days each northern hemisphere autumn) and blows offshore 25% of the time (22 days in an average northern hemisphere autumn). Over an average northern hemisphere autumn winds stronger than >40kph (25mph) are expected on 7 days at Anse de Cabestan
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.
