Arna Plage Wind Statistics, August averages since 2006
This image describes how commonly and how strongly the wind blows from different directions through a typical August. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 2480 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 not enough 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 prevailing wind at Arna Plage blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Arna Plage. On the other hand, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average 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 32% of the time (9 days in an average August). During a typical August wind stronger than >40kph (25mph) was predicted 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.
