The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 3472 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 too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the most common wind at Tuahine Point blows from the SSE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Tuahine Point. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.

Over an average July winds stronger than >40kph (25mph) are expected on 4 days at Tuahine Point
