Bell Block Reef Wind Stats

This image describes how commonly and how strongly the wind blows from different directions over a normal May. The biggest 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 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Bell Block Reef, located 13 km away (8 miles). There are insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the most common 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. By contrast, 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 May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 11% of the time (3 days each May) and blows offshore 35% of the time (7 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Bell Block Reef
