North wall Wind Stats

The graph describes how often and how strongly the wind blows from different directions over a normal July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to North wall, located 42 km away (26 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 dominant wind at North wall blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at North wall. 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 July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 9% of the time (3 days each July) and blows offshore 44% of the time (14 days in an average July). Over an average July winds stronger than >40kph (25mph) are expected on 3 days at North wall
