Mar da Frente Wind Stats

The figure describes how often and how strongly the wind blows from different directions over a normal May. 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 the darkest shade of blue. It is based on 3414 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Mar da Frente, located 41 km away (25 miles). There are too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Mar da Frente blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Mar da Frente. On the other hand, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 2% of the time (1 days each May) and blows offshore just 34% of the time (11 days in an average May). Over an average May winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Mar da Frente
