This chart describes how commonly and how strongly the wind blows from different directions through a typical April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by dark blue. It is based on 1630 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Corona Del Mar Jetty, located 16 km away (10 miles). There are too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Corona Del Mar Jetty 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 Corona Del Mar Jetty. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 36% of the time (11 days each April) and blows offshore 43% of the time (1 days in an average April). During a typical April winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Corona Del Mar Jetty
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.
