Sumpters Wind Stats

The graph illustrates how commonly and how strongly the wind blows from different directions over a normal June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by deep blue. It is based on 3266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Sumpters, located 20 km away (12 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 Sumpters blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Sumpters. 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. During a typical June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 15% of the time (4 days each June) and blows offshore 27% of the time (0 days in an average June). Over an average June wind stronger than >40kph (25mph) was forecast for only a single days at Sumpters
