San Angelo Wind Rose

A wind rose is a diagram, presented in circular format, that shows the distribution of wind direction and wind speed at a location over a period of time. The length of each bar represents the percent of time the wind blows from that direction. Each bar is subdivided with colors to show wind speed ranges associated with each direction. A wind rose can quickly show the dominant wind directions and the direction of the strongest wind speeds. These wind rose plots are created by the Iowa Environmental Mesonet.

The annual and individual monthly wind roses are shown below, for San Angelo. Clicking on these plots enables a larger view.
