Andrew Molera State Park Wind Statistics, Autumn averages since 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 suggests the strength, with the darkest shade of blue strongest. It is based on 7252 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Andrew Molera State Park, located 27 km away (17 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 prevailing wind at Andrew Molera State Park blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Andrew Molera State Park. On the other hand, dominant spokes represent 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 northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 28% of the time (25 days each northern hemisphere autumn) and blows offshore 47% of the time (43 days in an average northern hemisphere autumn). During a typical northern hemisphere autumn winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Andrew Molera State Park
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.
