Chicago has a season for everyone, but not every season is right for every traveler. Summer has the liveliest energy with festivals, lakefront activities, and warm evenings. Fall offers comfortable weather with smaller crowds. Spring is for those who love seeing green spaces come to life with fresh flowers and local activity, but are willing to gamble on warmth. And winter is for the bold, the budget-conscious, and anyone who has ever wanted a deep-dish pizza or a jazz bar to themselves.
This guide breaks down what to expect in Chicago every month of the year so you can plan around your priorities rather than just your calendar.
The Quick Answer: What is the Best Time to Visit Chicago?
The best time to visit Chicago is in late-summer through early-fall, specifically after Labor Day until mid-October. By that time, the city has quieted down with kids back in school and the weather is generally comfortable and warm.

Chicago by Season: What to Expect
Spring in Chicago (March, April, May)
What the weather is actually like
Chicago’s springs tend to jump back and forth between warm and cool days, with a potential for rain or snow. It’s one of the most unpredictable seasons. It’s been known to be 70º one day and snowing the next!
March is often still cold with occasional snow. It’s not an ideal time for outdoor activities, but on the irregular warm days, everyone flocks outside to enjoy the reprieve from frigid temperatures.
April’s weather is similar, but this is when Chicago slowly starts to liven up. After a gray and drab winter, the city plants its first flowers of the year, including the famed Michigan Avenue tulips. The city is suddenly full of color again. Though, rainy days are not uncommon and layering is essential.
May is typically very pleasant, especially later in the month and around Memorial Day. While it’s not really beach weather and the lake is still cold, the lakefront starts getting significantly busier with locals taking advantage of the Lakefront Trail. Weekends start to see more activity, and Memorial Day weekend officially kicks off the summer season.
Why visit in spring
The spring season typically sees fewer tourists than in summer, and hotels are generally less expensive as a result. However, if you’re looking for an active time to visit, the weekend before St. Patrick’s Day features one of the city’s most unique annual events: the Chicago River dyeing. Bars open early in the morning and throngs of spectators congregate along the riverfront to witness the river turn neon green. In the later spring months, the city feels fresh and energized as the flowers begin to bloom.
What to watch out for
Chicago’s weather can be unpredictable, especially in spring. Regardless of the forecast, be sure to pack layers to prepare for any kind of weather. Also, be aware that a majority of outdoor vendors and beach services don’t open until Memorial Day weekend at the end of May.
Summer in Chicago (June, July, August)
What the weather is actually like
Chicago’s summers are not terribly hot on average, but days are often humid. The average highs range between 75º to 85º. July and August are typically the hottest months, with occasional heat waves above 90º. Thunderstorms are also common in summer, especially after heat waves.
Why visit in summer
Chicago’s summers are unbeatable. You get access to dozens of freshwater beaches with skyline views, and the lakefront is buzzing with activity. Lake Michigan is warmest in August and it’s the perfect place to cool off on hot days.
Pro tip: Ohio Street Beach is one of the best downtown beaches to swim and/or kayak at.
In addition to lakefront recreation, there are countless festivals and events to engage in, including Taste of Chicago, the Chicago Air and Water Show, Lollapalooza, and the Navy Pier fireworks every Wednesday and Saturday night. With more daylight, there’s more time to explore outdoors and experience the best of Chicago’s warm evenings. Many restaurants offer outdoor dining, rooftop bars are plentiful, and sunset river cruises are one of the most popular evening activities. This is also the prime time for farmer’s markets, which usually open in May and run weekly through mid-October
What to watch out for
Since Chicago’s summers are so inviting, June through August is the peak season. Hotels are at their most expensive and popular tours book out well in advance, especially during busy event weekends like Lollapalooza and the Air and Water Show. Also, the Lakefront Trail is often crowded on summer weekends, so you need to prepare for congestion and be more aware of your surroundings (don’t walk in the bike lane!). Finally, the heat can be intense in July and August during the midday, so plan outdoor activities for mornings and evenings.
Fall in Chicago (September, October, November)
What the weather is actually like
The temperature starts to cool down in fall, but it remains relatively warm through mid-October. September is still warm with temperatures averaging between 65º to 75º with lower humidity. However, there have been occasional 90º days. October becomes crisp and beautiful with fall colors peaking in mid-to-late-October. Temperatures start to drop into the 50s later in the month. Snow is possible around then, but November is when it starts to get pretty chilly. Crowds thin out considerably by this time until the start of the holiday season.
Why visit in fall
September is arguably the best month in Chicago. The summer crowds have disappeared after Labor Day but the weather is still very comfortable, providing many opportunities to enjoy the outdoors without weaving through congested sidewalks, museums, or parks. However, there are still busy weekends throughout the season. The first weekend in September is popular for the free Jazz Festival in Millennium Park, and Labor Day vacationers make the most out of the long weekend. Mid-October brings the Chicago Marathon, and Halloween festivities attract a lot of nightlife activity. While the beginning of November is quiet, the back end of the month is filled with dozens of holiday activities, including the Millennium Park tree lighting and Magnificent Mile Lights Festival.
If you’re looking for a more budget-friendly time to travel but don’t want to visit in the bitter cold, hotel rates tend to drop after Labor Day (with the exception of the aforementioned major event weekends) and the weather stays decent through mid-October. As a bonus, the vibrant fall colors in the parks and along the Lakefront Trail are stunning.
What to watch out for
Some public facilities start to shut down after Labor Day weekend, though the true shoulder season doesn’t start until November. By the end of October/beginning of November, outdoor attractions like Buckingham Fountain begin to shut down until spring, harbors start to prepare for winter, public restrooms close, and restaurants remove outdoor seating. However, be aware that hotel prices spike during the Chicago Marathon weekend in October.
Winter in Chicago (December, January, February)
What the weather is actually like
Winter in Chicago is generally frigid and potentially snowy. Average highs through January and February range between 20º and 30º, but the wind chill makes it feel significantly colder. It is also not uncommon for a couple weeks to see sub-zero temperatures with weather outlets pushing out frostbite warnings. Snow is also expected from December through February, but January and February are the coldest and quietest months of the year.
Why visit in winter
Mid-winter is the cheapest time to visit Chicago by far. Hotel rates drop significantly, so it’s the best time to visit for those looking for the least expensive deals. While January and February are typically very quiet, the city remains lively throughout the holiday season in December. The annual Christkindlmarket draws millions of visitors downtown and Christmas-themed bars are packed. Ice skating in Millennium Park and Maggie Daley Park is a popular activity throughout the cold months, and museums, jazz bars, restaurants, and theaters are far less crowded after the holiday season. In addition, as long as the river hasn’t completely frozen over, Wendella’s architecture cruises run year-round. If you’re willing to endure the cold, the city’s architecture is arguably more dramatic against the winter skyline.
What to watch out for
With freezing temperatures and a potential for snow, outdoor activities are very limited. Winter is not the season to explore the Lakefront Trail. The wind coming off of Lake Michigan in January and February can be brutal and waves can become dangerously high. Know that some seasonal attractions and outdoor vendors close entirely throughout the season.

Common Mistakes When Planning a Chicago Trip by Season
Spring
- Underestimating spring’s unpredictability. April in Chicago can feel like three different seasons in a single week—heck, even a single day.
- Not packing layers, including a rain jacket and winter jacket (this goes for fall, too).
Summer
- Booking a summer weekend trip without reserving tours and restaurants well in advance. Activities fill up fast during Chicago’s peak season.
- Visiting only during peak summer months and missing the benefits of September and October (better temps and fewer crowds).
Fall
- Ruling out October because it’s considered part of the shoulder season. The temperature can still get pretty warm, and the Chicago Marathon and Halloween events make the city busier than some expect.
- Expecting perfect autumn days. The way the midwest’s weather is, it can randomly be 80º or even 90º in early October, and then it can get frigid and snowy by the end of the month.
Winter
- Visiting in January or February without knowing how cold the wind chill can feel.
- Planning outdoor-heavy itineraries in November through February without backup indoor options.
Final Thoughts: Planning Your Chicago Trip by Season
The “best time” to visit Chicago depends entirely on what kind of trip you want and what kind of traveler you are. Regardless of the season you choose to visit, you will always find things to do in Chicago. You can sample the city’s extensive restaurants scene, search for a seasonal event, and/or join a tour.
FAQs About the Best Time to Visit Chicago
September is the best month to visit Chicago for many reasons: warm temperatures (especially in the first half of the month), fewer crowds, cheaper hotels after Labor Day, and events like Jazz Festival and Bike the Drive. In short, you can experience the best of Chicago summer but without the chaotic crowds. It’s a sweet spot in the year that many visitors overlook.
Yes, Chicago can be worth visiting in winter for the right traveler. Budget travelers, food enthusiasts, and anyone who loves the cold will appreciate the city in the freezing months. Also, if you choose to visit in December, there are countless holiday activities like the famed Christkindlmarket, Zoo Lights, and holiday walking tours.
Despite what some might expect, Chicago’s summers can be very hot. Temperatures average between 75º to 85º in July and August, but there are occasional week-long heat waves of above 90º. Chicago also does not have a dry heat—the moisture from the lake makes it incredibly humid, which makes it feel even hotter. While it doesn’t get quite as hot as states like Florida or Texas, don’t expect to fully escape intense summer heat. Mornings and evenings are the best times for outdoor activities during this time.
Compared to many other Midwest cities, Chicago hasn’t been getting a significant amount of snow the past few years. According to Farmer’s Almanac, Chicago doesn’t even rank in the 17 snowiest cities in the country. That being said, it does inevitably snow quite a few inches on multiple occasions, typically between the end of October through March. The average annual snowfall is between 35 and 40 inches.
Yes, Chicago gets incredibly crowded in summer. July and August are the city’s peak season. Expect popular attractions like Navy Pier, Millennium Park, and the Lakefront Trail to be extremely busy, especially on summer weekends. Book hotels, restaurants, and tours well in advance, and plan visits to the most popular areas for weekday mornings.
May is typically an excellent time to visit Chicago, but March and April are riskier. Early spring is a nice time to visit for those looking for lower prices, but the weather is unpredictable. Come May, the city starts to open up again and its green spaces come to life.
