Cachagua Wind Stats

The biggest 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 the darkest shade of blue.

There are insufficient 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 prevailing wind at Cachagua blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Cachagua.
