Ohara Wind Stats

The figure illustrates how commonly and how strongly the wind blows from different directions over a normal November. The longest 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 2867 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ohara, located 30 km away (19 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 prevailing wind at Ohara blows from the ESE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Ohara. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 6% of the time (2 days each November) and blows offshore 16% of the time (5 days in an average November). Over an average November winds stronger than >40kph (25mph) are expected on 2 days at Ohara
