Statistiques de Vent de Atlantic Terrace, moyennes sur Septembre depuis 2006
This picture illustrates how often and how strongly the wind blows from different directions through a typical September. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2400 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Atlantic Terrace, located 2 km away (1 miles). There are insufficient 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 Atlantic Terrace blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Atlantic Terrace. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average September, the model suggests that winds are light enough for the sea to be glassy (light blue) about 10% of the time (3 days each September) and blows offshore 28% of the time (8 days in an average September). During a typical September wind stronger than >40kph (25mph) was forecast for only a single days at Atlantic Terrace
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.
