This picture illustrates how often and how strongly the wind blows from different directions over a normal May. The largest 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 1488 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Padang Padang, located 24 km away (15 miles). There are not enough 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 Padang Padang blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Padang Padang. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 13% of the time (4 days each May) and blows offshore 94% of the time (29 days in an average May). Over an average May winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) at Padang Padang
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.
