Waipaoa River Wind Stats

The rose diagram 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 implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Waipaoa River, located 32 km away (20 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 prevailing wind at Waipaoa River blows from the SSE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Waipaoa River. Converseley, dominant spokes represent favoured directions, and the more dark 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 8% of the time (2 days each April) and blows offshore 29% of the time (9 days in an average April). In a typical April winds stronger than >40kph (25mph) are expected on 2 days at Waipaoa River
