Ruapuke Wind Stats

The rose diagram shows how often and how strongly the wind blows from different directions through a typical July. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests 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 Ruapuke, located 27 km away (17 miles). There are insufficient 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 Ruapuke blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ruapuke. Converseley, dominant spokes show favoured directions, and the more deep 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 6% of the time (2 days each July) and blows offshore 26% of the time (8 days in an average July). During a typical July winds stronger than >40kph (25mph) are expected on 5 days at Ruapuke
