Southend Reef Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions through a typical August. The largest 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 dark blue. It is based on 2975 NWW3 forecasts of wind since since 2008, at 3hr intervals, for the closest NWW3 model node to Southend Reef, located 32 km away (20 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 dominant wind at Southend Reef blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Southend Reef. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 0.7% of the time (0 days each August) and blows offshore just 1.0% of the time (0 days in an average August). In a typical August wind stronger than >40kph (25mph) was predicted for only a single days at Southend Reef
