This image shows how often and how strongly the wind blows from different directions over a normal June. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 1594 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to San Carlos Point, located 50 km away (31 miles). There are insufficient 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 San Carlos Point blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at San Carlos Point. 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. During a typical June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 50% of the time (15 days each June) and blows offshore 77% of the time (0 days in an average June). Over an average June winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at San Carlos Point
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.
