Blue Bay Wind Stats

This picture shows 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 suggests the strength, with deep 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 Blue Bay, located 72 km away (45 miles). There are insufficient 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 most common wind at Blue Bay blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Blue Bay. Converseley, dominant spokes illustrate 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 (the lightest shade of blue) about 10% of the time (3 days each May) and blows offshore 11% of the time (3 days in an average May). Over an average May wind stronger than >40kph (25mph) was predicted for only a single days at Blue Bay
