Anse des Lezards Wind Statistics, May averages since 2006
The figure shows how commonly and how strongly the wind blows from different directions through a typical May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 2200 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Anse des Lezards, located 18 km away (11 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 most common wind at Anse des Lezards blows from the NE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Anse des Lezards. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, 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 May) and blows offshore just 7% of the time (0 days in an average May). During a typical May winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) at Anse des Lezards
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.
