Anse Couleuvre Wind Statistieken, Herfst gemiddelde vanaf 2006
This picture describes how commonly and how strongly the wind blows from different directions through a typical northern hemisphere autumn. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep 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 Couleuvre, located 28 km away (17 miles). There are too few 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 Anse Couleuvre blows from the NNE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Anse Couleuvre. By contrast, 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 autumn, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 0.9% of the time (1 days each northern hemisphere autumn) and blows offshore just 16% of the time (10 days in an average northern hemisphere autumn). In a typical northern hemisphere autumn winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) at Anse Couleuvre
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.
