Wind Stats
The graph describes how often and how strongly the wind blows from different directions over a normal March. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 3460 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Whitsand Bay and Tregantle, located 42 km away (26 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 dominant wind at Whitsand Bay and Tregantle blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Whitsand Bay and Tregantle. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 5% of the time (2 days each March) and blows offshore 20% of the time (6 days in an average March). Over an average March winds stronger than >40kph (25mph) are expected on 5 days at Whitsand Bay and Tregantle
