Wainui Reef Wind Stats

This image illustrates how commonly and how strongly the wind blows from different directions over a normal April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 3359 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Wainui Reef, located 28 km away (17 miles). There are too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Wainui Reef blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Wainui Reef. By contrast, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each April) and blows offshore 51% of the time (7 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 3 days at Wainui Reef
