This chart illustrates how frequently and how strongly the wind blows from different directions through a typical November. 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 dark blue. It is based on 1680 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Puaena Point, located 42 km away (26 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 most common wind at Puaena Point blows from the NNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Puaena Point. On the other hand, 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 November, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (2 days each November) and blows offshore 33% of the time (10 days in an average November). In a typical November wind stronger than >40kph (25mph) was forecast for only a single days at Puaena 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.
