Dunbar/Belhaven Bay Wind Stats

The graph illustrates how commonly and how strongly the wind blows from different directions over a normal September. The largest 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 2880 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Dunbar/Belhaven Bay, located 33 km away (21 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 dominant wind at Dunbar/Belhaven Bay blows from the NE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Dunbar/Belhaven Bay. On the other hand, 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 September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (2 days each September) and blows offshore 20% of the time (1 days in an average September). Over an average September wind stronger than >40kph (25mph) was forecast for only a single days at Dunbar/Belhaven Bay
