Aberaeron Wind Statistics, Junho averages since 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions over a normal June. 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 the darkest shade of blue. It is based on 2303 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. No doubt 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. Converseley, 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. During a typical June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 13% of the time (4 days each June) and blows offshore 24% of the time (0 days in an average June). Over an average June wind stronger than >40kph (25mph) was expected for only a single 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.
