Cow Bay Wind Stats

The rose diagram describes how frequently 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 indicates the strength, with deep 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 Cow Bay, located 13 km away (8 miles). There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Cow Bay blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Cow Bay. Converseley, dominant spokes illustrate 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 (the lightest shade of blue) about 4% of the time (1 days each April) and blows offshore just 14% of the time (4 days in an average April). Over an average April wind stronger than >40kph (25mph) was forecast for only a single days at Cow Bay
