Aberdaron Wind Stats

The rose diagram illustrates how often and how strongly the wind blows from different directions through a typical August. The longest 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 deep blue. It is based on 3573 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 not enough 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 dominant wind at Aberdaron blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Aberdaron. On the other hand, dominant spokes show favoured directions, and the more dark 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). In a typical August winds stronger than >40kph (25mph) are expected on 2 days at Aberdaron
