What’s the weather like in Chicago in July?

Chicago is in the Midwest of the United States and sits on the south-west shores of Lake Michigan. The region’s waters do affect its weather, with Chicago having consistent rain all year round. The wettest months are over summer, meaning you’re likely to see showers in July. This is also the hottest and sunniest month of the year, though, so try and pack for all weathers if you’re visiting the city.


The average temperature in Chicago is 23ºC in July, peaking at 29ºC in the hottest part of the afternoon. With 12 hours of sunshine each day, try to protect yourself by applying plenty of sun cream when you visit. Around 100mm of rain’s predicted over 12 days in July, so it’s worth bringing a waterproof jacket or umbrella. You’re also likely to need some warmer layers for the evenings, as temperatures drop to a low of 17ºC after dark.
