Ano Nuevo Wind Statistics, August averages since 2006
This chart describes how often and how strongly the wind blows from different directions over a normal August. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of 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 Ano Nuevo, located 21 km away (13 miles). There are too few 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 Ano Nuevo blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ano Nuevo. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 9% of the time (3 days each August) and blows offshore 9% of the time (0 days in an average August). Over an average August winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) 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.
