Plum Island Wind Stats

This chart describes how commonly and how strongly the wind blows from different directions over a normal April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Plum Island, located 34 km away (21 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 most common wind at Plum Island blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Plum Island. Converseley, dominant spokes illustrate favoured directions, and the more the darkest shade of 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 (pale blue) about 8% of the time (2 days each April) and blows offshore 33% of the time (8 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 2 days at Plum Island
