Fernald Point Wind Stats

The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical October. The largest 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 3070 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Fernald Point, located 48 km away (30 miles). There are insufficient 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 prevailing wind at Fernald Point blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Fernald Point. 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. Over an average October, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 22% of the time (7 days each October) and blows offshore 38% of the time (2 days in an average October). In a typical October wind stronger than >40kph (25mph) was predicted for only a single days at Fernald Point
