This image describes how commonly and how strongly the wind blows from different directions through a typical November. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 1680 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Nungas, located 27 km away (17 miles). There are too few 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 prevailing wind at Nungas blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Nungas. On the other hand, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average November, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 48% of the time (14 days each November) and blows offshore 62% of the time (6 days in an average November). During a typical November winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Nungas
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.
