This chart describes how commonly and how strongly the wind blows from different directions through a typical southern hemisphere spring. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 5144 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to La Brava, located 18 km away (11 miles). There are insufficient 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 dominant wind at La Brava blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at La Brava. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere spring, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (7 days each southern hemisphere spring) and blows offshore 8% of the time (8 days in an average southern hemisphere spring). During a typical southern hemisphere spring winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at La Brava
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.
