Nobbys Reef Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Nobbys Reef, located 21 km away (13 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 most common wind at Nobbys Reef blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Nobbys Reef. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each April) and blows offshore 27% of the time (8 days in an average April). Over an average April wind stronger than >40kph (25mph) was predicted for only a single days at Nobbys Reef
