Cape St Francis Wind Stats

This picture describes how commonly and how strongly the wind blows from different directions through a typical April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Cape St Francis, located 37 km away (23 miles). There are too few 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 Cape St Francis blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Cape St Francis. By contrast, 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 0.6% of the time (0 days each April) and blows offshore just 2% of the time (1 days in an average April). In a typical April wind stronger than >40kph (25mph) was expected for only a single days at Cape St Francis
