Anglet - L'Ocean Wind Statistieken, Zomer gemiddelde vanaf 2006
This image describes how often and how strongly the wind blows from different directions through a typical northern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 7265 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anglet - L'Ocean, located 38 km away (24 miles). There are insufficient 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 prevailing wind at Anglet - L'Ocean 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 - L'Ocean. Converseley, 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 northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of 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). In a typical northern hemisphere summer wind stronger than >40kph (25mph) was forecast for only a single days at Anglet - L'Ocean
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.
