Statistiques de Vent de Airport Rights, moyennes sur Décembre depuis 2006
The graph illustrates how frequently and how strongly the wind blows from different directions over a normal December. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 2457 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Airport Rights, located 33 km away (21 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 dominant wind at Airport Rights blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Airport Rights. On the other hand, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical December, the model suggests that winds are light enough for the sea to be glassy (light blue) about 36% of the time (11 days each December) and blows offshore 44% of the time (13 days in an average December). Over an average December winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Airport Rights
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.
