Aoshima Wind Stats

The figure illustrates how often 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 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aoshima, located 34 km away (21 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 prevailing wind at Aoshima blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aoshima. Converseley, dominant spokes represent favoured directions, and the more deep 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 (pale blue) about 16% of the time (5 days each September) and blows offshore 32% of the time (10 days in an average September). Over an average September wind stronger than >40kph (25mph) was forecast for only a single days at Aoshima
