Estadísticas de Viento para Annestown, Promedio de septiembre desde 2006
This chart shows 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 suggests the strength, with the strongest winds shown by deep blue. It is based on 2400 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Annestown, located 21 km away (13 miles). There are too few 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 Annestown 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 Annestown. By contrast, dominant spokes illustrate favoured directions, and the more the darkest shade of 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 (the lightest shade of blue) about 8% of the time (2 days each September) and blows offshore 20% of the time (0 days in an average September). During a typical September wind stronger than >40kph (25mph) was predicted for only a single days at Annestown
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.
