Intro

What’s the weather like in Chicago in August?

The city of Chicago is in the Midwest state of Illinois, along the shores of Lake Michigan and close to the border with Indiana and Wisconsin. Otherwise known as the ‘Windy City’, Chicago has a humid continental climate with warm summers and very cold winters. In August, the city’s often sunny and balmy, but there’s a chance of showers from time to time so make sure you bring a light waterproof jacket.

Averages

In August, the average temperature in Chicago is a pleasant 22°C, reaching highs of 28°C and lows of 16°C after dark. In the daytime, the weather can be very warm so you’ll need to pack your summer wardrobe for trips to Chicago at this time of year, along with some warmer layers for evenings out. Just under 100mm of rain’s expected in August across 13 wet days, so you’ll need to be prepared for some showers.
