Anse de Cabestan Wind Statistics, January averages since 2006
This picture illustrates how commonly and how strongly the wind blows from different directions through a typical January. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 2372 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 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 Anse de Cabestan blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Anse de Cabestan. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average January, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each January) and blows offshore just 21% of the time (7 days in an average January). During a typical January winds stronger than >40kph (25mph) are expected on 5 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.
