The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical July. The longest 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 deep blue. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anse a La Gourde, located 35 km away (22 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 a La Gourde blows from the E. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Anse a La Gourde. On the other hand, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from.

During a typical July winds exceeding >40kph (25mph) are not expected, but 13 have winds on the range 30-40 (19-25) at Anse a La Gourde
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.
