Motu River Wind Stats

The figure illustrates how commonly and how strongly the wind blows from different directions over a normal May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 2838 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 too few 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 dominant wind at Motu River blows from the NNE. 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 illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each May) and blows offshore 21% of the time (2 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Motu River
