Great Exhibition Bay Wind Stats

The rose diagram describes how frequently 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 strongest. It is based on 3192 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Great Exhibition Bay, located 18 km away (11 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 dominant wind at Great Exhibition Bay blows from the NE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Great Exhibition Bay. On the other hand, dominant spokes show favoured directions, and the more deep 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 (pale blue) about 0.3% of the time (0 days each May) and blows offshore just 3% 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 Great Exhibition Bay
