Statistiques de Vent de Augusta Rivermouth, moyennes sur Novembre depuis 2006
The figure describes how often and how strongly the wind blows from different directions over a normal November. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 2387 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Augusta Rivermouth, located 24 km away (15 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 prevailing wind at Augusta Rivermouth blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Augusta Rivermouth. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 1.0% of the time (0 days each November) and blows offshore just 3% of the time (1 days in an average November). Over an average November wind stronger than >40kph (25mph) was forecast for only a single days at Augusta Rivermouth
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.
