Takegashima Wind Stats

The figure shows how frequently and how strongly the wind blows from different directions through a typical August. The longest 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 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Takegashima, located 18 km away (11 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 dominant wind at Takegashima blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Takegashima. By contrast, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (light blue) about 16% of the time (5 days each August) and blows offshore 31% of the time (9 days in an average August). In a typical August winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Takegashima
