Indicator Wind Stats

This picture illustrates how frequently and how strongly the wind blows from different directions through a typical September. The longest 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 Indicator, located 32 km away (20 miles). There are not enough 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 dominant wind at Indicator blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Indicator. By contrast, dominant spokes show favoured directions, and the more deep 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 5% of the time (2 days each September) and blows offshore 6% of the time (0 days in an average September). During a typical September winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Indicator
