This picture illustrates how often and how strongly the wind blows from different directions through a typical March. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by deep blue. It is based on 1724 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Pasta Point, located 21 km away (13 miles). There are too few 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 Pasta Point blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Pasta Point. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 29% of the time (9 days each March) and blows offshore 62% of the time (19 days in an average March). During a typical March winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Pasta 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.
