Waipu River Wind Stats

This image describes how frequently and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Waipu River, located 46 km away (29 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 Waipu 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 Waipu River. On the other hand, dominant spokes illustrate 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 8% of the time (2 days each April) and blows offshore 35% of the time (9 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 2 days at Waipu River
