Statistiques de Vent de Anglet - Corsaires, moyennes sur Printemps depuis 2006
This chart shows how often and how strongly the wind blows from different directions over a normal northern hemisphere spring. The longest 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 6580 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Anglet - Corsaires, located 37 km away (23 miles). There are too few 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 Anglet - Corsaires 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 Anglet - Corsaires. By contrast, 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 spring, the model suggests that winds are light enough for the sea to be glassy (light blue) about 19% of the time (17 days each northern hemisphere spring) and blows offshore 33% of the time (28 days in an average northern hemisphere spring). Over an average northern hemisphere spring winds stronger than >40kph (25mph) are expected on 5 days at Anglet - Corsaires
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.
