Matauri Bay Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions over a normal April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Matauri Bay, located 9 km away (6 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 most common wind at Matauri Bay blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Matauri Bay. By contrast, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each April) and blows offshore 30% of the time (1 days in an average April). Over an average April wind stronger than >40kph (25mph) was expected for only a single days at Matauri Bay
