Matosinhos Wind Stats

The figure shows how commonly and how strongly the wind blows from different directions through a typical September. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Matosinhos, located 32 km away (20 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 dominant wind at Matosinhos blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Matosinhos. By contrast, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average September, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 21% of the time (6 days each September) and blows offshore 27% of the time (8 days in an average September). During a typical September wind stronger than >40kph (25mph) was predicted for only a single days at Matosinhos
