What’s the weather like in Chicago in April?

Located in the state of Illinois alongside Lake Michigan, Chicago has a humid, continental climate and is affectionately known as the ‘Windy City’. April falls within the spring months, but Chicago is still quite mild at this time of year as the city gradually warms up after the freezing winter. If you visit in April, make sure you pack for all weathers as you may see sunshine, rain and cooler temperatures, especially at night.


In April, the average daytime temperature in Chicago is a mild 10°C, with highs of 15°C in the peak of the afternoon. Although the weather’s mild at this time of year, this is a good month for visiting the city to avoid the hot summer temperatures and explore the sights in comfort. Around 100mm of rain is expected over the course of 12 wet days in April, so you’ll need to bring a rain jacket. At night, the temperature falls to a chilly low of 4°C.
