Wind Stats
This picture describes how commonly and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by deep blue. It is based on 3120 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Perran Sands, located 29 km away (18 miles). There are not enough 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 prevailing wind at Perran Sands blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Perran Sands. 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 April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (2 days each April) and blows offshore 34% of the time (6 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 3 days at Perran Sands
