Estadísticas de Viento para Annestown, Promedio de Otoño desde 2006
This picture illustrates how commonly and how strongly the wind blows from different directions through a typical northern hemisphere autumn. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 7252 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 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 dominant wind at Annestown blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Annestown. By contrast, dominant spokes show 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 northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (5 days each northern hemisphere autumn) and blows offshore 15% of the time (1 days in an average northern hemisphere autumn). In a typical northern hemisphere autumn winds stronger than >40kph (25mph) are expected on 10 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.
