Statistiques de Vent de Audierne, moyennes sur Juillet depuis 2006
This picture shows how often and how strongly the wind blows from different directions through a typical July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Audierne, located 4 km away (2 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 prevailing wind at Audierne blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Audierne. On the other hand, 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 July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 9% of the time (3 days each July) and blows offshore 28% of the time (3 days in an average July). In a typical July wind stronger than >40kph (25mph) was predicted for only a single days at Audierne
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.
