The largest 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 the darkest shade of blue. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Mahia Spit, located 12 km away (7 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 Mahia Spit blows from the ENE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Mahia Spit. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 2% of the time (1 days each July) and blows offshore just 9% of the time (3 days in an average July). During a typical July winds stronger than >40kph (25mph) are expected on 2 days at Mahia Spit
