(any wind direction)

This picture shows how frequently and how strongly the wind blows from different directions through a typical March. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 3460 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Porth Nobla, located 26 km away (16 miles). There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Porth Nobla blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Porth Nobla. Converseley, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 10% of the time (3 days each March) and blows offshore 18% of the time (2 days in an average March). During a typical March winds stronger than >40kph (25mph) are expected on 3 days at Porth Nobla
