Bonny Hills Wind Stats

This chart illustrates how commonly and how strongly the wind blows from different directions through a typical September. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Bonny Hills, located 18 km away (11 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 dominant wind at Bonny Hills blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Bonny Hills. By contrast, 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 September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 11% of the time (3 days each September) and blows offshore 31% of the time (9 days in an average September). In a typical September wind stronger than >40kph (25mph) was forecast for only a single days at Bonny Hills
