Anglet - Corsaires Wind Statistics, September averages since 2006
This picture shows how frequently and how strongly the wind blows from different directions over a normal September. The biggest 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 2399 NWW3 forecasts of wind since since 2006, 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. Without question 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 plot shows a nearly round shape, 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 September, the model suggests that winds are light enough for the sea to be glassy (light blue) about 25% of the time (8 days each September) and blows offshore 43% of the time (12 days in an average September). Over an average September wind stronger than >40kph (25mph) was expected for only a single 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.
