Haitan Bay (Haitan Dao) Wind Stats

This picture shows how commonly and how strongly the wind blows from different directions over a normal May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Haitan Bay (Haitan Dao), located 19 km away (12 miles). There are not enough 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 dominant wind at Haitan Bay (Haitan Dao) blows from the NE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Haitan Bay (Haitan Dao). On the other hand, dominant spokes illustrate favoured directions, and the more dark 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 (the lightest shade of blue) about 0.4% of the time (0 days each May) and blows offshore just 6% of the time (1 days in an average May). Over an average May wind stronger than >40kph (25mph) was expected for only a single days at Haitan Bay (Haitan Dao)
