This image describes how commonly and how strongly the wind
blows from different directions through a typical northern
hemisphere winter. 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 deep
blue. It is based on 5048 NWW3 forecasts of wind since since
2006, at 3hr intervals, for the closest NWW3 model node to Playa
de Regla, located 26 km away (16 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
most common wind at Playa de Regla blows from the W. If the rose
diagram shows a close to circular outline, it means there is no
strong bias in wind direction at Playa de Regla. By contrast,
dominant spokes show favoured directions, and the more the
darkest shade of blue, the stronger the wind. Spokes point in
the direction the wind blows from. Over
