Statistiques de Vent de A Street, moyennes sur Août depuis 2006
The graph describes how commonly and how strongly the wind blows from different directions through a typical August. The biggest 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 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to A Street, located 33 km away (21 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at A Street blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at A Street. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 11% of the time (3 days each August) and blows offshore 36% of the time (0 days in an average August). In a typical August winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at A Street
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.
