Statistiques de Vent de Avalanche, moyennes sur Juin depuis 2006
The figure shows how frequently and how strongly the wind blows from different directions through a typical June. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by deep blue. It is based on 2306 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Avalanche, located 41 km away (25 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 prevailing wind at Avalanche blows from the NW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Avalanche. 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 June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 0.6% of the time (0 days each June) and blows offshore just 9% of the time (3 days in an average June). In a typical June winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Avalanche
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.
