The figure shows how frequently and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 1646 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Priests Cove, located 25 km away (16 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 most common wind at Priests Cove blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Priests Cove. Converseley, dominant spokes represent 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 (light blue) about 9% of the time (3 days each April) and blows offshore 32% of the time (5 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 3 days at Priests Cove
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.
