Aberaeron Wind Statistieken, September gemiddelde vanaf 2006
The figure illustrates how frequently 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 dark blue. It is based on 2397 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 not enough 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 WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aberaeron. 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 September, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each September) and blows offshore 22% of the time (1 days in an average September). During a typical September winds stronger than >40kph (25mph) are expected on 2 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.
