Anse a La Gourde Wind Statistics, Summer averages since 2006
This chart describes how often and how strongly the wind blows from different directions through a typical northern hemisphere summer. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 7266 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 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 dominant wind at Anse a La Gourde blows from the ENE. 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. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 0.7% of the time (1 days each northern hemisphere summer) and blows offshore just 1.1% of the time (1 days in an average northern hemisphere summer). In a typical northern hemisphere summer wind stronger than >40kph (25mph) was predicted for only a single days 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.
