Statistiques de Vent de Azurara, moyennes sur Août depuis 2006
The figure describes how often and how strongly the wind blows from different directions through a typical August. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Azurara, located 28 km away (17 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 prevailing wind at Azurara blows from the WNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Azurara. By contrast, 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 16% of the time (5 days each August) and blows offshore 18% of the time (6 days in an average August). During a typical August winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Azurara
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.
