Statistiques de Vent de Air Guling, moyennes sur Février depuis 2006
This picture illustrates how often and how strongly the wind blows from different directions over a normal February. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2102 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Air Guling, located 29 km away (18 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 Air Guling blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Air Guling. On the other hand, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical February, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 32% of the time (9 days each February) and blows offshore 51% of the time (9 days in an average February). Over an average February winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Air Guling
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.
