(any wind direction)

This image shows how frequently and how strongly the wind blows from different directions through a typical March. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 3460 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Green Hills, located 31 km away (19 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 dominant wind at Green Hills blows from the SSE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Green Hills. By contrast, 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 March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 5% of the time (2 days each March) and blows offshore 14% of the time (4 days in an average March). In a typical March winds stronger than >40kph (25mph) are expected on 2 days at Green Hills
