Motuau Island Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions through a typical May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Motuau Island, located 4 km away (2 miles). There are not enough recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Motuau Island blows from the NNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Motuau Island. Converseley, 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 May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 0% of the time (0 days each May) and blows offshore just 0% of the time (0 days in an average May). During a typical May winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Motuau Island
