This picture shows how often and how strongly the wind blows from different directions over a normal June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 1594 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to La Pepita, located 4 km away (2 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 prevailing wind at La Pepita blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at La Pepita. 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 June, the model suggests that winds are light enough for the sea to be glassy (light blue) about 5% of the time (2 days each June) and blows offshore 28% of the time (8 days in an average June). Over an average June winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at La Pepita
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.
