Havaizinho Wind Stats

The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 1240 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Havaizinho, located 15 km away (9 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Havaizinho blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Havaizinho. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from.
