Anglet - Les Dunes Wind Statistieken, Zomer gemiddelde vanaf 2006
This picture describes how often and how strongly the wind blows from different directions over a normal northern hemisphere summer. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 7265 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anglet - Les Dunes, located 38 km away (24 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 most common wind at Anglet - Les Dunes 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 - Les Dunes. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (light blue) about 26% of the time (24 days each northern hemisphere summer) and blows offshore 37% of the time (33 days in an average northern hemisphere summer). Over an average northern hemisphere summer wind stronger than >40kph (25mph) was expected for only a single days at Anglet - Les Dunes
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.
