Mahia Reef Wind Stats

This image illustrates how often and how strongly the wind blows from different directions over a normal May. 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 deep blue. It is based on 3414 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Mahia Reef, located 56 km away (35 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 most common wind at Mahia Reef blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Mahia Reef. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 7% of the time (2 days each May) and blows offshore 12% of the time (1 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 3 days at Mahia Reef
