La Portada Wind Stats

The longest 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 the darkest shade of blue. It is based on 3471 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to La Portada, located 55 km away (34 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 La Portada blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at La Portada. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.
