Arna Plage Wind Statistics, August averages since 2006
This image describes how commonly and how strongly the wind blows from different directions over a normal August. 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 2414 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Arna Plage, located 14 km away (9 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 most common wind at Arna Plage blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Arna Plage. On the other hand, dominant spokes show 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 20% of the time (6 days each August) and blows offshore 31% of the time (9 days in an average August). Over an average August wind stronger than >40kph (25mph) was forecast for only a single days at Arna Plage
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
