Mangamaunu Wind Stats

This picture illustrates how frequently and how strongly the wind blows from different directions over a normal July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Mangamaunu, located 30 km away (19 miles). There are insufficient 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 prevailing wind at Mangamaunu blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Mangamaunu. On the other hand, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 14% of the time (4 days each July) and blows offshore 42% of the time (13 days in an average July). Over an average July winds stronger than >40kph (25mph) are expected on 3 days at Mangamaunu
