North Durras Reef Wind Stats

The graph illustrates how often and how strongly the wind blows from different directions over a normal July. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates 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 North Durras Reef, located 24 km away (15 miles). There are too few 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 dominant wind at North Durras Reef blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at North Durras Reef. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 9% of the time (3 days each July) and blows offshore 45% of the time (13 days in an average July). Over an average July wind stronger than >40kph (25mph) was forecast for only a single days at North Durras Reef
