Estadísticas de Viento para Aberavon, Promedio de Todo el Año desde 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions over a normal year. 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 28039 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aberavon, located 16 km away (10 miles). There are too few 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 Aberavon blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aberavon. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical year, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 9% of the time (33 days each year) and blows offshore 22% of the time (44 days in an average year). Over an average year winds stronger than >40kph (25mph) are expected on 33 days at Aberavon
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.
