Wind Stats
The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical March. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 3460 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Three Arch Bay, located 21 km away (13 miles). There are insufficient 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 Three Arch Bay blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Three Arch Bay. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 40% of the time (12 days each March) and blows offshore 48% of the time (14 days in an average March). In a typical March winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Three Arch Bay
