Anglet - Les Dunes Wind Statistieken, Winter gemiddelde vanaf 2006
The figure describes how often and how strongly the wind blows from different directions over a normal northern hemisphere winter. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by deep blue. It is based on 6931 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 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 Anglet - Les Dunes blows from the WNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Anglet - Les Dunes. By contrast, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (light blue) about 13% of the time (12 days each northern hemisphere winter) and blows offshore 30% of the time (27 days in an average northern hemisphere winter). Over an average northern hemisphere winter winds stronger than >40kph (25mph) are expected on 11 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.
