Blacks Reef Wind Stats

This picture illustrates how frequently and how strongly the wind blows from different directions through a typical April. 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 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Blacks Reef, located 54 km away (34 miles). There are not enough 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 Blacks Reef blows from the S. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Blacks Reef. On the other hand, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (2 days each April) and blows offshore 25% of the time (7 days in an average April). In a typical April winds stronger than >40kph (25mph) are expected on 2 days at Blacks Reef
