Kahana Bay Wind Stats

This chart describes how commonly and how strongly the wind blows from different directions over a normal April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by dark blue. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Kahana Bay, located 39 km away (24 miles). There are too few 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 most common wind at Kahana Bay blows from the NE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Kahana Bay. By contrast, dominant spokes illustrate 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 (pale blue) about 3% of the time (1 days each April) and blows offshore just 4% of the time (1 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 3 days at Kahana Bay
