J-Bay Wind Statistics, Summer averages since 2006

The graph describes how often and how strongly the wind blows from different directions over a normal southern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 7765 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to J-Bay, located 50 km away (31 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 prevailing wind at J-Bay blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at J-Bay. 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 southern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (light blue) about 7% of the time (6 days each southern hemisphere summer) and blows offshore 29% of the time (26 days in an average southern hemisphere summer). Over an average southern hemisphere summer winds stronger than >40kph (25mph) are expected on 10 days at J-Bay

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.
