Anglet - Marinella Wind Statistics, Summer averages since 2006
The graph describes how frequently and how strongly the wind blows from different directions through a typical northern hemisphere summer. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of 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 - Marinella, located 37 km away (23 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 dominant wind at Anglet - Marinella 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 - Marinella. Converseley, dominant spokes represent favoured directions, and the more dark 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 predicted 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.
