Takegashima Wind Stats

This picture shows how often and how strongly the wind blows from different directions through a typical May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 3430 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Takegashima, located 18 km away (11 miles). There are insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Takegashima blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Takegashima. 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. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 13% of the time (4 days each May) and blows offshore 33% of the time (9 days in an average May). In a typical May winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Takegashima
