Anse de Vauville Wind Statistics, April averages since 2006
This picture shows how frequently and how strongly the wind blows from different directions through a typical April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 2157 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Anse de Vauville, located 19 km away (12 miles). There are too few 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 prevailing wind at Anse de Vauville blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Anse de Vauville. By contrast, 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 April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each April) and blows offshore 12% of the time (2 days in an average April). In a typical April wind stronger than >40kph (25mph) was forecast for only a single days at Anse de Vauville
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.
