'WIND ROSE' PLOT FOR THE MONTH
The 'petals' represent wind direction and the length represents frequency, i.e. in this case winds from the SSW were the most common.

The colours represent the strength of the wind, with black being weakest through medium blue then lighter colours (cyan, light green, yellow, magenta, red) being stronger
