Matadeiro Wind Stats

The figure describes how commonly and how strongly the wind blows from different directions through a typical November. 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 deep blue. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Matadeiro, located 16 km away (10 miles). There are not enough 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 Matadeiro blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Matadeiro. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 9% of the time (3 days each November) and blows offshore 42% of the time (12 days in an average November). In a typical November winds stronger than >40kph (25mph) are expected on 4 days at Matadeiro
