Port Robinson Wind Stats

The rose diagram illustrates how often and how strongly the wind blows from different directions through a typical June. The longest 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 showing the strongest winds. It is based on 3506 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Port Robinson, located 20 km away (12 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 Port Robinson blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Port Robinson. 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. Over an average June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 15% of the time (4 days each June) and blows offshore 53% of the time (16 days in an average June). In a typical June winds stronger than >40kph (25mph) are expected on 2 days at Port Robinson
