The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by dark blue. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Mahanga Point, located 9 km away (6 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 Mahanga Point blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Mahanga 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 2 days at Mahanga Point
