Anse de Cabestan Wind Statistics, April averages since 2006
The graph illustrates how often and how strongly the wind blows from different directions through a typical April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 2160 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Anse de Cabestan, located 11 km away (7 miles). There are insufficient 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 Anse de Cabestan blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Anse de Cabestan. 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. Over an average April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each April) and blows offshore 35% of the time (10 days in an average April). During a typical April wind stronger than >40kph (25mph) was expected for only a single days at Anse de Cabestan
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.
