Motu River Wind Stats

The graph describes how often and how strongly the wind blows from different directions through a typical April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Motu River, located 40 km away (25 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 prevailing wind at Motu River blows from the NE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Motu River. By contrast, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 12% of the time (4 days each April) and blows offshore 24% of the time (2 days in an average April). In a typical April winds stronger than >40kph (25mph) are expected on 2 days at Motu River
