Tolcarne Wind Stats

The figure describes how often and how strongly the wind blows from different directions over a normal April. 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 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Tolcarne, located 31 km away (19 miles). There are insufficient 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 Tolcarne blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Tolcarne. On the other hand, dominant spokes illustrate favoured directions, and the more dark 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 (the lightest shade of blue) about 9% of the time (3 days each April) and blows offshore 37% of the time (7 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 2 days at Tolcarne
