Cap Ferret Wind Statistics, All Year averages since 2006
The figure describes how commonly and how strongly the wind blows from different directions through a typical year. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 23151 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Cap Ferret, located 24 km away (15 miles). There are not enough recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Cap Ferret blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Cap Ferret. On the other hand, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average year, the model suggests that winds are light enough for the sea to be glassy (light blue) about 11% of the time (40 days each year) and blows offshore 36% of the time (128 days in an average year). During a typical year winds stronger than >40kph (25mph) are expected on 22 days at Cap Ferret
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.
