Tam O'Shanter Wind Stats

The figure describes how often and how strongly the wind blows from different directions through a typical May. 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 deep blue. It is based on 3428 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Tam O'Shanter, located 6 km away (4 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 Tam O'Shanter blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Tam O'Shanter. On the other hand, 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 May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 14% of the time (4 days each May) and blows offshore 38% of the time (7 days in an average May). In a typical May winds stronger than >40kph (25mph) are expected on 2 days at Tam O'Shanter
