The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark 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 Spew Pits blows from the N. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Spew Pits. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.

Over an average July winds stronger than >40kph (25mph) are expected on 2 days at Spew Pits
