Ferrugem Wind Stats

The figure shows how frequently and how strongly the wind blows from different directions through a typical June. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 3026 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ferrugem, located 15 km away (9 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Ferrugem blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ferrugem. By contrast, 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. Over an average June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 14% of the time (4 days each June) and blows offshore 46% of the time (14 days in an average June). In a typical June winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Ferrugem
