Bell Block Reef Wind Stats

The figure describes how frequently and how strongly the wind blows from different directions through a typical November. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Bell Block Reef, located 13 km away (8 miles). There are too few 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 Bell Block Reef blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Bell Block Reef. On the other hand, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (3 days each November) and blows offshore 23% of the time (4 days in an average November). During a typical November wind stronger than >40kph (25mph) was predicted for only a single days at Bell Block Reef
