The largest 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 dark blue. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Lava Rock, located 32 km away (20 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Lava Rock blows from the SSE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Lava Rock. On the other hand, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.
