Worldwide Wind Roses - Graphics and Tabular Data

Iowa Environmental Mesonet: Wind Rose Plots

Dataset Tabs Default Display


Check wind speed and direction at locations around the world. The Iowa Environmental Mesonet (IEM) collects a range of environmental data from observing networks around the world. Users can access tabular data and / or wind rose plots for thousands of locations (mostly at airports) around the world.

Wind roses are graphical charts that characterize the speed and direction of winds measured at weather stations. Presented in a circular format, the length of each "spoke" around the circle indicates the amount of time that the wind blows from the indicated direction. Colors along the spokes indicate categories of wind speed. 

Where do these data come from?

The Iowa Environmental Mesonet (IEM) collects environmental data from cooperating members with observing networks. Many of the networks are similar to Automated Surface Observing Systems (ASOS) installed at airports in the United States. Data collected at each site are stored and made available on this website, organized into networks based on their geography and/or the organization that administers the network.
