Estadísticas de Viento para Airport Lefts, Promedio de Otoño desde 2006
The graph describes how often and how strongly the wind blows from different directions through a typical southern hemisphere autumn. The longest 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 dark blue. It is based on 6580 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Airport Lefts, located 33 km away (21 miles). There are not enough recording stations world wide to use actual wind data. No doubt 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 SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Airport Lefts. By contrast, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (light blue) about 27% of the time (25 days each southern hemisphere autumn) and blows offshore 78% of the time (71 days in an average southern hemisphere autumn). In a typical southern hemisphere autumn winds exceeding >40kph (25mph) are not expected, but 5 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.
