When to go to Chicago?
The humidity in Chicago is quite high all year round, which makes the cold winters and spring months seem even harder. Basically a cosmopolitan city like Chicago is of course open all year round, but the temperatures from November to April can be a real challenge for vacationers.
From May it gets noticeably warmer, the summer months are hot and in autumn Chicago still remains sunny and mild. Accordingly, the best time to travel to Chicago in Illinois is from mid-May to the end of September. October can also be a wonderful time to travel to the city on Lake Michigan in warmer years.
You must have heard of the nickname “Windy City” as Chicago’s nickname. Many travel guides associate this term with the strong wind that often whistles through the skyscrapers of the skyline. However, historians attribute the term “Windy City” more to the windy activities of certain smuggling gangs that were once very common in Chicago. Other sources said that the inhabitants of Cincinnati gave Chicago this somewhat derogatory epithet.
No matter whether it is a small rivalry between Ohio and Illinois or “Windy City” has a completely different origin: The fact is that Chicago is not significantly windier than other coastal cities in the USA according to official weather records and measurements.
