Nine Mile Reef Wind Stats

The figure illustrates how frequently 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 implies the strength, with deep blue strongest. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Nine Mile Reef, located 50 km away (31 miles). There are insufficient 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 dominant wind at Nine Mile Reef blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Nine Mile Reef. 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 July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each July) and blows offshore just 7% of the time (2 days in an average July). In a typical July winds stronger than >40kph (25mph) are expected on 2 days at Nine Mile Reef
