This chart illustrates how commonly and how strongly the wind blows from different directions through a typical April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Vaiaau, located 16 km away (10 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 Vaiaau 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 Vaiaau. 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 April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 11% of the time (3 days each April) and blows offshore 70% of the time (21 days in an average April). In a typical April winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Vaiaau
