Cyrils and Big Left Wind Stats

The largest 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 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Cyrils and Big Left, located 2 km away (1 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 prevailing wind at Cyrils and Big Left blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Cyrils and Big Left. 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 August, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each August) and blows offshore 33% of the time (10 days in an average August). During a typical August wind stronger than >40kph (25mph) was expected for only a single days at Cyrils and Big Left
