Tuahine Point Wind Stats

The figure illustrates how frequently and how strongly the wind blows from different directions through a typical September. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Tuahine Point, located 33 km away (21 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 Tuahine Point 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 Tuahine Point. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average September, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 7% of the time (2 days each September) and blows offshore 35% of the time (10 days in an average September). During a typical September winds stronger than >40kph (25mph) are expected on 2 days at Tuahine Point
