This chart illustrates how often and how strongly the wind blows from different directions over a normal November. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 1680 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Njerve Pipeline, located 11 km away (7 miles). There are too few 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 Njerve Pipeline blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Njerve Pipeline. Converseley, dominant spokes show 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 November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each November) and blows offshore just 7% of the time (0 days in an average November). Over an average November winds stronger than >40kph (25mph) are expected on 2 days at Njerve Pipeline
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
