This image describes how often and how strongly the wind blows from different directions through a typical May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 1734 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Aberta A Nova, located 27 km away (17 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 Aberta A Nova blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Aberta A Nova. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each May) and blows offshore 8% of the time (2 days in an average May). In a typical May winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Aberta A Nova

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.
