Opoutere Beach Wind Stats

The rose diagram describes how frequently 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 implies the strength, with the darkest shade of blue strongest. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Opoutere Beach, located 16 km away (10 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 most common wind at Opoutere Beach 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 Opoutere Beach. By contrast, dominant spokes show favoured directions, and the more the darkest shade of 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 11% of the time (3 days each May) and blows offshore 43% of the time (3 days in an average May). Over an average May wind stronger than >40kph (25mph) was expected for only a single days at Opoutere Beach
