Anse des Cayes Wind Statistics, December averages since 2006
The graph illustrates how often and how strongly the wind blows from different directions over a normal December. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 2457 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anse des Cayes, located 19 km away (12 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 most common wind at Anse des Cayes blows from the NE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Anse des Cayes. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical December, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each December) and blows offshore just 5% of the time (0 days in an average December). Over an average December wind stronger than >40kph (25mph) was forecast for only a single days at Anse des Cayes
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.
