(any wind direction)

The figure illustrates how commonly 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 suggests 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 Siyayi, located 33 km away (21 miles). There are too few 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 prevailing wind at Siyayi blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Siyayi. Converseley, dominant spokes illustrate 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 (light blue) about 11% of the time (3 days each March) and blows offshore 22% of the time (7 days in an average March). During a typical March winds stronger than >40kph (25mph) are expected on 2 days at Siyayi
