Cupsogue Wind Stats

The figure illustrates how commonly and how strongly the wind blows from different directions through a typical July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Cupsogue, located 35 km away (22 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 Cupsogue blows from the S. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Cupsogue. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 5% of the time (2 days each July) and blows offshore 18% of the time (6 days in an average July). In a typical July wind stronger than >40kph (25mph) was expected for only a single days at Cupsogue
