Anglet - Les Dunes Wind Statistieken, April gemiddelde vanaf 2006
The graph describes how often and how strongly the wind blows from different directions through a typical April. The longest 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 deep blue. It is based on 2160 NWW3 forecasts of wind since since 2007, 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. 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. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 18% of the time (5 days each April) and blows offshore 33% of the time (10 days in an average April). During a typical April 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.
