(any wind direction)

This chart illustrates how often and how strongly the wind blows from different directions through a typical March. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep 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 Shark Alley, located 30 km away (19 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 Shark Alley blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Shark Alley. By contrast, dominant spokes show 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 March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each March) and blows offshore 31% of the time (3 days in an average March). In a typical March winds stronger than >40kph (25mph) are expected on 2 days at Shark Alley
