Greenough Wind Stats

This chart shows how frequently and how strongly the wind blows from different directions over a normal September. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Greenough, located 23 km away (14 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 Greenough blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Greenough. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 6% of the time (2 days each September) and blows offshore 16% of the time (5 days in an average September). Over an average September winds stronger than >40kph (25mph) are expected on 2 days at Greenough
