Aberdaron Wind Statistics, Agosto averages since 2006
This picture describes how commonly and how strongly the wind blows from different directions through a typical August. The biggest 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 dark blue. It is based on 2479 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aberdaron, located 36 km away (22 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Aberdaron blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aberdaron. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each August) and blows offshore 12% of the time (0 days in an average August). During a typical August wind stronger than >40kph (25mph) was expected for only a single days at Aberdaron
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.
