Green Ball Wind Stats

The figure shows how frequently and how strongly the wind blows from different directions through a typical June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 3266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Green Ball, located 25 km away (16 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 prevailing wind at Green Ball blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Green Ball. On the other hand, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 4% of the time (1 days each June) and blows offshore just 5% of the time (2 days in an average June). In a typical June winds exceeding >40kph (25mph) are not expected, but 6 have winds on the range 30-40 (19-25) at Green Ball
