(any wind direction)

The figure describes how commonly and how strongly the wind blows from different directions over a normal May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Grunters, located 46 km away (29 miles). There are not enough 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 dominant wind at Grunters blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Grunters. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 7% of the time (2 days each May) and blows offshore 32% of the time (10 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 5 days at Grunters
