The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2880 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to North Stradbroke-Cylinders, located 11 km away (7 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 North Stradbroke-Cylinders blows from the ENE.

During a typical September, 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 September) and blows offshore 19% of the time (6 days in an average September). Over an average September wind stronger than >40kph (25mph) was expected for only a single days at North Stradbroke-Cylinders
