Stuart Rocks Wind Stats

The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Stuart Rocks, located 26 km away (16 miles). 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 dominant wind at Stuart Rocks blows from the NE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Stuart Rocks. Converseley, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.
