Statistiques de Vent de Ano Nuevo, moyennes sur Automne depuis 2006
This chart shows how often and how strongly the wind blows from different directions through a typical northern hemisphere autumn. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 7252 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ano Nuevo, located 21 km away (13 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 Ano Nuevo 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 Ano Nuevo. On the other hand, 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 northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (6 days each northern hemisphere autumn) and blows offshore 11% of the time (4 days in an average northern hemisphere autumn). In a typical northern hemisphere autumn wind stronger than >40kph (25mph) was forecast for only a single days at Ano Nuevo
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.
