Big River Wind Stats

The figure describes how commonly and how strongly the wind blows from different directions over a normal September. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by deep blue. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Big River, located 28 km away (17 miles). There are insufficient 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 most common wind at Big River blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Big River. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical September, the model suggests that winds are light enough for the sea to be glassy (light blue) about 16% of the time (5 days each September) and blows offshore 26% of the time (7 days in an average September). Over an average September wind stronger than >40kph (25mph) was expected for only a single days at Big River
