Rock Wave Wind Stats

The graph shows how frequently and how strongly the wind blows from different directions through a typical July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Rock Wave, located 18 km away (11 miles). There are insufficient 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 most common wind at Rock Wave blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Rock Wave. By contrast, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 10% of the time (3 days each July) and blows offshore 37% of the time (11 days in an average July). In a typical July winds stronger than >40kph (25mph) are expected on 3 days at Rock Wave
