What is the Weather Like in Chicago, Illinois? – Our Chicago Weather Guide!

Visit Chicago in the summer or the fall.

We repeat, visit Chicago in the summer or the fall.

 

The Midwestern American winters are nothing to scoff at. They are downright frigid, and besides, there isn’t much going on during Chicago’s LONG and beaten winter months. We say LONG because while other places in the world are celebrating the beginning of spring, Chicago is participating in Winter Part 2, as the city is still owned by snow and freezing rain. So What is the weather like in Chicago Illinois year round?

What is the Weather Like in Chicago, IllinoisGawd dammit it’s cold!

Well, let’s be fair to Chicago’s Winter Part 1 and Winter Part 2 because the summer weather isn’t that great either. It is suffocating in its humidity, and the hot, muggy weather, along with big crowds of folks partaking in festivals and other major attractions, can make for a miserable experience if you don’t have the right attitude.

So, we’ll be clear, Chicago didn’t become the second-most visited city in America because of its weather. This iconic city brings in 55 million visitors a year because of its impressive culture, cuisine, and sports, not the depressing weather.

 

The Basics of Chicago, Illinois, Weather and When to Visit

If you aren’t visiting Chicago for one of the many music or cultural festivals in the summer, the best time to visit is in the fall. The autumn months are normally sunny, but not hot, and the crowds are thinner as summer vacations have come to a close. The fall window is small, though, and includes late September to mid-November. The end of November does see snow sometimes, so if you are unwilling to slog through the snow with the locals then schedule a trip before then, just to be safe.

If you are open to fluctuating weather conditions that bring a mix of cold and warm weather, then April isn’t a bad time to go to Chicago. The lines are shorter at the major attractions and the hotel prices are lower, but you might be wrestling with snow plows and snow boots.

The most important thing when visiting Chicago is to plan ahead and make reservations early. The inexpensive and moderately-priced hotels sell out fast, especially on the weekends in the months of June, July, and August. You’ll also want to be on the lookout for conventioneers. Large conventions lock up hotels with thousands of people and send the price of available rooms soaring. Big conventions include the Restaurant Show in May and the Housewares Show in March. During those weeks, major hotels in downtown Chicago are booked solid, so you will be on the outskirts of town looking inward.

 

Take a look here for a searchable list of every convention in the City for the next 18 months to see if there is a clash. Total numbers of over 30,000 spell doom for your trip!

The Reason for “The Windy City” Nickname- It might not be what you expect?

Chicago_in_summer

As you head into Chicago, you surely are aware of the city’s nickname, “The Windy City.” In an article focused on Chicago weather – like this one – you should know the reason for this moniker. Assumptions are always made that it has something to do with the tireless winds that push across Lake Michigan to knock you over upon arrival. However, that theory is only partially true.

Besides being a very windy city, the nickname stuck because of its reputation of having boastful citizens and politicians, or “windbags” full of “hot air.” In fact, legend claims that New York Sun editor Charles Dana cautioned its readers to ignore the “nonsensical claims of the Windy City” in an 1890 article. See, New York and Chicago had a serious rivalry at the time, and the two cities were competing for the 1893 World Fair, which Chicago won.

The metaphorical jab by Dana stuck, it seems, but even historians are unclear which came first, the Lake Michigan breeze or the Chicago citizenry boasts. If it were only the wind that mattered, Boston would hold the crown, for it is the windiest city in America, with average wind speeds of 12.4 mph. Chicago comes in 12th, with an average of 10.3 mph. However, it is a little windier on the edge of the lake, so when you are flying into Chicago O’Hare, expect some turbulence.

 

Monthly Weather Conditions in Chicago, Illinois 

Chicago in AutumnChicago in Autumn

People in Chicago wait for those perfect days between hot and humid summers and relentlessly cold winters. Those in-between days make this friendly town even friendlier because it is hard to beat this iconic city when the sun is out and the breeze blows back the humidity.

However, there is nothing predictable about Chicago weather in the spring and autumn months. Packing appropriately is essential. It might rain, it might snow, or you might get an 85-degree day. In many cases, you will wake up needing a winter coat, rain boots, and an umbrella, and downsize to a short-sleeve T-shirt by mid-afternoon.

The sunniest part of the year in Chicago is the four-month period from mid-June to the end of October. The clearest days of the year are at the end of August, but even then, it is clear, mostly clear, or partly cloudy only 68 percent of the time. The rest of the year, the sky is overcast nearly 60 percent of the time. Overall, Chicago has only 189 sunny days per year, while the U.S. average is 205.

May is the rainiest month of the year in Chicago, and the city sees 122 rainy days a year. October is the driest month. While there are numerous incidents of snow flurries in Chicago per year, the city averages 11 days a year in which at least one inch of snow accumulates. If you stay from the beginning of December to the beginning of March, you are likely to see some snow.

Here are the weather conditions you should expect to see from January to December, with average highs and lows, precipitation, humidity, and wind speed as calculated at Midway International Airport:

 

What You Should Pack for a Trip to Chicago, Illinois

When packing clothes for Chicago, think “layers” because of the unpredictable weather. The following are tips for what to pack before heading to the Windy City:

 

  • From fall to spring bring winter gear in the form of coats, hats, gloves, and scarves.

 

  • In the winter, bring a set of thermal underwear, which helps block the chill. Thermals are a Chicago staple and your first line of defense against the cold. You won’t regret your decision to throw on a set before heading out of your hotel room.

 

  • Your shoes should consist of casual, comfortable walking shoes and a set of rain or snow boots, depending on the time of year you plan to visit.

 

  • There are some great spots for swimming in Lake Michigan, but the water temperature is usually pretty chilly even in the summer months. The best time to bring a swimsuit and flip-flops is August, with water temperatures topping out in the upper 70s, sometimes reaching 80 degrees.

 

  • Regardless of the time of year, you plan to travel to Chicago, bring a water-resistant jacket with a hood, and an umbrella.

 

  • When visiting Chicago in the summer months, bring light breathable clothes because the humidity is a beast, along with a light jacket or sweater for the late evenings and early mornings.

 

No one visits Chicago for the weather unless they are a masochist. People visit Chicago because it is an iconic metropolitan city with a lot of history and culture – as far as American city’s go. It also has a great festival scene that covers the things humans love the most from culinary and cars to music, art, and dance. Not to mention, the sports teams like the Bulls, Bears, and Cubs.

Chicago really has it all, and that is why so many people flock to the city, but the weather doesn’t always cooperate with the enthusiasm of its residents and tourists. If you find a few sunny days with low humidity, feel blessed, but be prepared for the worst and pack appropriately, and always do what the locals do, suck it up and have fun anyways.
