Audierne Wind Statistics, Autumn averages since 2006
The figure describes how often and how strongly the wind blows from different directions through a typical northern hemisphere autumn. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 7252 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 too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Audierne blows from the WSW. 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 show 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 autumn, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (7 days each northern hemisphere autumn) and blows offshore 26% of the time (15 days in an average northern hemisphere autumn). In a typical northern hemisphere autumn winds stronger than >40kph (25mph) are expected on 7 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.
