The biggest 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 2306 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Otago Peninsula - Allans Beach, located 21 km away (13 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 most common wind at Otago Peninsula - Allans Beach blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Otago Peninsula - Allans Beach. On the other hand, 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.

Over an average June winds stronger than >40kph (25mph) are expected on 5 days at Otago Peninsula - Allans Beach
