The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2879 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Morfa Mawr, located 16 km away (10 miles). There are too few 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 Morfa Mawr blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Morfa Mawr. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from.
