Statistiques de Vent de Airport Lefts, moyennes sur Octobre depuis 2006
This chart describes how frequently and how strongly the wind blows from different directions through a typical October. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Airport Lefts, located 33 km away (21 miles). There are too few 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 Airport Lefts blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Airport Lefts. By contrast, 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 October, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 18% of the time (6 days each October) and blows offshore 88% of the time (27 days in an average October). In a typical October winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Airport Lefts
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.
