The graph shows how often and how strongly the wind blows from different directions through a typical January. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 1728 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Curren's Point, located 27 km away (17 miles). There are insufficient recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Curren's Point blows from the ESE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Curren's Point. Converseley, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average January, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each January) and blows offshore 29% of the time (6 days in an average January). In a typical January winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Curren's 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.
