The Harbour Wind Stats

This image illustrates how commonly and how strongly the wind blows from different directions through a typical September. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to The Harbour, located 16 km away (10 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at The Harbour blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at The Harbour. 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. Over an average September, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 4% of the time (1 days each September) and blows offshore just 33% of the time (9 days in an average September). In a typical September wind stronger than >40kph (25mph) was expected for only a single days at The Harbour
