North wall Wind Stats

The graph shows how frequently and how strongly the wind blows from different directions through a typical April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue strongest. It is based on 2880 NWW3 forecasts of wind since since 2007, 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. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing 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 represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each April) and blows offshore 25% of the time (8 days in an average April). In a typical April winds stronger than >40kph (25mph) are expected on 3 days at North wall
