The rose diagram illustrates how often and how strongly the wind blows from different directions through a typical December. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 3448 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aberffraw, located 20 km away (12 miles). There are insufficient 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 prevailing wind at Aberffraw 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 Aberffraw. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average December, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each December) and blows offshore just 8% of the time (1 days in an average December). In a typical December winds stronger than >40kph (25mph) are expected on 6 days at Aberffraw
