Prainha Wind Stats

The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 1200 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Prainha, located 23 km away (14 miles).
