Dunes Wind Stats

The rose diagram shows how frequently and how strongly the wind blows from different directions over a normal July. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Dunes, located 6 km away (4 miles). There are not enough 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 Dunes blows from the NE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Dunes. On the other hand, dominant spokes illustrate 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 (pale blue) about 0.9% of the time (0 days each July) and blows offshore just 1.0% of the time (0 days in an average July). Over an average July winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Dunes
