Statistiques de Vent de Aberaeron, moyennes sur Toute l'Année depuis 2006
The graph illustrates how commonly 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 implies the strength, with the strongest winds shown by deep blue. It is based on 28031 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aberaeron, located 32 km away (20 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 most common wind at Aberaeron blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aberaeron. Converseley, dominant spokes show favoured directions, and the more deep 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 (light blue) about 8% of the time (29 days each year) and blows offshore 21% of the time (7 days in an average year). Over an average year winds stronger than >40kph (25mph) are expected on 40 days at Aberaeron
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.
