Anse Trabaud Wind Statistics, Autumn averages since 2006
This picture describes how commonly and how strongly the wind blows from different directions through a typical northern hemisphere autumn. 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 7252 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anse Trabaud, located 19 km away (12 miles). There are insufficient 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 Anse Trabaud blows from the E. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Anse Trabaud. 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 northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (3 days each northern hemisphere autumn) and blows offshore just 4% of the time (0 days in an average northern hemisphere autumn). During a typical northern hemisphere autumn winds stronger than >40kph (25mph) are expected on 3 days at Anse Trabaud
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.
