Tarnos - La Digue Wind Statistics, June averages since 2006
This image illustrates how often and how strongly the wind blows from different directions over a normal June. The biggest 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 1833 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Tarnos - La Digue, located 39 km away (24 miles). There are insufficient 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 dominant wind at Tarnos - La Digue blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Tarnos - La Digue. By contrast, 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. During a typical June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 25% of the time (8 days each June) and blows offshore 37% of the time (10 days in an average June). Over an average June winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Tarnos - La Digue
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.
