High Rock Wind Stats

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 the darkest shade of blue. It is based on 3720 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to High Rock, located 32 km away (20 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 most common wind at High Rock blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at High Rock. By contrast, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 0.5% of the time (0 days each July) and blows offshore just 0.6% of the time (0 days in an average July). Over an average July winds exceeding >40kph (25mph) are not expected, but 9 have winds on the range 30-40 (19-25) at High Rock
