Middle Rock Wind Stats

The rose diagram shows how often and how strongly the wind blows from different directions over a normal August. 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 the darkest shade of blue. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to MiddleRock, located 16 km away (10 miles). There are not enough 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 MiddleRock blows from the S. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at MiddleRock. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical August, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 9% of the time (3 days each August) and blows offshore 24% of the time (7 days in an average August). Over an average August winds stronger than >40kph (25mph) are expected on 3 days at MiddleRock
