What is a wind rose diagram?

A wind rose diagram is a graphic tool utilized by meteorologists to view wind speeds and direction. Wind rose diagrams exhibit a specific land area, such as a town or a community.

Wind rose diagrams are circular graphs that show the frequency of winds blowing in various directions. Winds are depicted as colored spokes around the center of the graph. The length of each spoke indicates the wind’s frequency and direction. Wind diagrams also have concentric circles surrounding the center of the graph to denote different frequencies and to display the time and speed of a given wind. This allows users to read the graph easily.
