You have probably heard of the nickname “Windy City” in Chicago. Many travel guides associate this term with the strong wind that often whistles through the skyscrapers. Historians, however, attribute the term “Windy City” to the windy activities of certain smuggling gangs that were once very common in Chicago. Other sources said Cincinnati residents gave Chicago this somewhat derogatory nickname.

Regardless of whether it is a small rivalry between Ohio and Illinois or “Windy City” has a completely different origin: the fact is that, according to official weather records and measured values, Chicago is not significantly windier than other coastal cities in the USA.
