High Rock Wind Stats

The graph shows how commonly and how strongly the wind blows from different directions over a normal August. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 3582 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 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 dominant wind at High Rock blows from the ENE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at High Rock. 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 August, the model suggests that winds are light enough for the sea to be glassy (light blue) about 3% of the time (1 days each August) and blows offshore just 4% of the time (1 days in an average August). Over an average August winds exceeding >40kph (25mph) are not expected, but 4 have winds on the range 30-40 (19-25) at High Rock
