Anglet - Marinella Wind Statistieken, August gemiddelde vanaf 2006
The rose diagram shows how commonly and how strongly the wind blows from different directions through a typical August. 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 dark blue. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anglet - Marinella, located 37 km away (23 miles). There are not enough 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 - Marinella 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 - Marinella. Converseley, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 26% of the time (8 days each August) and blows offshore 38% of the time (11 days in an average August). During a typical August wind stronger than >40kph (25mph) was expected for only a single days at Anglet - Marinella
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.
