What to pack for Chicago in winter: the complete checklist

Packing for a Chicago winter

Chicago in winter is very doable if you pack like a local. This guide covers November through March, with month-by-month weather from the National Weather Service, a full packing checklist, and notes for holiday events, Bears games, theatre nights and family trips.

• January is the coldest month: normal high 31.6°F (–0.2°C), low 18.8°F (–7.3°C), per NWS Chicago's 1991–2020 normals.
• The three things to get right: an insulated, windproof coat that covers your hips, a merino or synthetic base layer, and waterproof boots with good grip.
• Small items that matter: a hat that covers your ears, mittens or touchscreen gloves, a neck gaiter, lip balm, hand warmers and a power bank. Cold drains phone batteries fast.

Packing for the cold usually means planning for it too. Most winter visitors lean on the museums, the aquarium and the observation decks on the coldest days, and the Chicago CityPASS ($144 per adult, 4.7/5 from more than 1,000 reviews) covers Shedd Aquarium and Skydeck plus three more indoor or outdoor picks, valid for nine days from first use. You can save the indoor stops for the days the wind is worst. The calendar shows live availability for your dates.

How cold is Chicago in winter? Month-by-month weather

The figures below are the official 1991–2020 normals for Chicago (O'Hare), published by NWS Chicago. Celsius values are converted and rounded.

The normal seasonal snowfall is 38.4 inches (about 97.5 cm), and about 36.9 inches of that falls between November and March. On average, January has 3.5 nights at or below 0°F.

Averages hide the swings, though. Two recent seasons show how much winters vary:

• November 2025 was unusually snowy. O'Hare recorded 8.4 inches on November 29, 2025, the snowiest November day on record there. NWS Chicago ranked the month the 7th snowiest November on record, with 10.4 inches.
• The rest of that season was dry. NWS Chicago reported that December to February 2026 brought 21.9 inches, which is 7.7 inches below normal. Adding up the NWS monthly and seasonal figures gives a 2025–26 total of 34.1 inches at O'Hare, which matches the independent count from triptravelingguide.com. That's a little under the 38.4-inch normal.

So bring boots even in November, and don't count on deep snow in January either.

Wind chill: the number that matters most

Chicago's wind, especially near the lake and between Loop high-rises, makes it feel much colder than the thermometer says. The NWS gives an example: 0°F with a 15 mph wind feels like –19°F, and at that wind chill exposed skin can freeze in 30 minutes. NWS frostbite guidance shrinks that to about 10 minutes at wind chills of –32°F or colder, and 5 minutes at –48°F or colder.

Extreme cold does happen. During the January 2019 polar vortex, O'Hare fell to –23°F on January 30, its coldest reading in 34 years, and stayed below zero for 52 straight hours. The wind chill hit –52°F, which the Chicago NWS ranked as the city's fifth coldest since 1929. The city's all-time record low is –27°F, set on January 20, 1985. Outbreaks like that are rare, but they explain why locals cover every inch of skin on the worst days.

Lake-effect snow, slush and salt

When cold air crosses the warmer waters of Lake Michigan, it can drop narrow bands of heavy snow. The NWS notes that conditions can range from whiteout to dry just a few miles apart. These bands most often hit northwest Indiana, though the Chicago lakefront gets them too.

Day to day, the bigger nuisance comes after the snow: slush puddles at every crosswalk, refrozen ice in the mornings, and road salt that leaves white stains on leather and suede.

The Chicago layering system: how locals dress

Chicagoans don't wear one giant sweater. They dress in three layers, the same approach the CDC recommends for cold weather:

1. Base layer (next to skin): merino wool or synthetic thermals that wick sweat. The CDC notes that wool, silk or polypropylene hold more body heat than cotton. Lightweight merino works for city walking; save midweight for outdoor events.
2. Mid layer (insulation): a fleece, wool sweater or light down vest.
3. Outer layer (wind and weather): the coat. This is the item to spend on.

The "Chicago coat." On the CTA in January you'll see one silhouette everywhere: a long, hooded down or synthetic parka that covers the hips and often reaches the knees. Look for:

• windproof, water-resistant fabric
• a hood that cinches, or one with a fur-style ruff
• a two-way zipper so you can sit and walk
• knit storm cuffs at the wrists
• fill power around 600 or higher for down, or a comparable synthetic fill

Well-known, widely available options include The North Face, Columbia, Patagonia, Arc'teryx and Canada Goose (the premium end).

Plan to overheat indoors. Museums, the "L," restaurants and theatres are well heated. Wear layers you can peel off, and choose a coat that's comfortable to carry or check. Sweating and then stepping back outside is how people get chilled. The CDC specifically advises removing layers when you feel too warm.

The master Chicago winter packing checklist

Clothing

• 2–3 base-layer tops (merino or synthetic)
• 1–2 base-layer bottoms (thermal leggings or long johns)
• 2 warm mid layers (fleece, wool sweater or down vest)
• Jeans or chinos for everyday wear, plus thermals underneath on cold days
• Lined or fleece-backed pants for long outdoor stretches
• One "nice" outfit for dinner or theatre (dark jeans or trousers with a sweater is fine in Chicago)
• Sleepwear and a light layer for overheated hotel rooms

Outerwear

• Insulated, windproof parka that covers your hips (December to February), or a warm insulated jacket for November and March
• Packable down or synthetic "puffy" layer as a backup

Footwear

• Waterproof, insulated boots with a deep-lug rubber sole
• 3–5 pairs of merino wool socks
• Slip-on traction cleats for icy days (they fit in a coat pocket)
• Optional: a second pair of comfortable water-resistant shoes for indoor days

Accessories

• Warm hat that covers your ears (wool or fleece-lined)
• Touchscreen gloves for city use, plus mittens or insulated gloves for long outdoor events
• Scarf or fleece neck gaiter that can go up over your nose
• Air-activated hand and toe warmers
• Sunglasses (snow glare is real)
• Small daypack or crossbody bag (and a clear stadium bag if you're going to a game)

Toiletries

• SPF lip balm (wind plus dry heated air means chapped lips by day two)
• Rich moisturizer and hand cream
• Travel-size saline spray or a small humidifier if you're prone to dry sinuses
• Tissues (cold wind means a runny nose)

Tech

• Power bank (10,000 mAh or more)
• Charging cables and a compact wall plug
• Phone kept in an inside pocket, not a back or outer pocket

Apple Support says iPhones are designed for ambient temperatures between 32° and 95°F (0–35°C). In colder conditions, battery life can temporarily shorten and the phone may shut off or stop charging until it warms up. A Chicago January takes you below that range.

Documents and misc

• Ventra card or a phone wallet set up for CTA tap-to-pay
• Mobile tickets saved to your phone wallet ahead of time
• Attraction pass, if you're using one (see our Chicago CityPASS and Go City comparison)
• Packing cubes to keep bulky layers compressed
• Carry-on suitcase with room for boots (or wear your boots on the plane)
• Insulated travel mug for coffee walks

Month-by-month packing adjustments

• November: Expect highs near 48°F and lows just above freezing. An insulated jacket plus a mid layer usually works, but pack a hat, gloves and waterproof boots, since November 2025 proved early snow can be serious. Heading in for the holiday kickoff? See our guide to Chicago in November 2026.
• December: Switch to the full parka. Evening events (the markets and lights) are colder than daytime sightseeing, so pack thermals and hand warmers.
• January: Peak cold. Wear a base layer every day, a face-covering gaiter, and mittens for longer walks. Build in indoor time: the Field Museum and the other museums on Museum Campus, the Art Institute and the observation decks all work on the coldest days.
• February: Nearly as snowy as January on average (10.7 inches). Pack the same as January, with extra socks for slushy days.
• March: The most changeable month. Highs average 47°F, but nights still dip below freezing and some snow is normal. Pack a warm jacket and layers, with waterproof shoes over heavy snow boots.

Packing by activity

Magnificent Mile Lights Festival and Christkindlmarket

The 2026 Wintrust Magnificent Mile Lights Festival is on Saturday, November 21. The parade steps off at 5:30 p.m., and you'll be standing still on the curb after dark. Wear thermal bottoms, insulated boots and toe warmers, and bring a hat and mittens.

Christkindlmarket Chicago at Daley Plaza runs November 20 to December 24, 2026, its 30th anniversary season. There's no need to pack a mug: drinks come in the market's collectible souvenir mug, which cost $10 empty in 2025 (2026 prices are posted at the market). Do leave space in your bag to carry it home, and wrap it in a sock. Bring some cash, since many vendors take only cash, and touchscreen gloves for the stalls that take cards. A guided holiday food and walking tour ($85, rated 4.8/5 but from only 19 reviews) includes VIP entry to the market and spends three hours outdoors, so dress for the parade, not for the shops. Both events, with dates, times and the rest of the month's calendar, are in our November 2026 events guide.

Ice skating at Millennium Park

The McCormick Tribune Ice Rink is free with your own skates, but reservations are required. Last season (2025–26) it ran from November 21 into early February. Skate rentals cost $17 on weekdays and $21 on weekends and holidays, plus a $5 admission charge at peak times. 2026–27 dates and prices hadn't been confirmed when we wrote this, so check before you go.

What to wear:

• warm leggings or thermals under stretchy pants (stiff denim gets cold and wet if you fall)
• a snug hat
• waterproof or insulated gloves
• tall wool socks to cushion rental skates

A Bears game at Soldier Field

Late-season home games in 2026–27 include November 22, December 6, December 25 (Packers, noon) and January 3 (Lions). The NFL can flex kickoff times. Sitting still for three-plus hours by the lake is the coldest thing most visitors do in Chicago. Bears game tickets are sold through the team and resale sites, so confirm the seat details before you pay.

How to dress:

• midweight base layers top and bottom
• two mid layers
• your warmest parka
• insulated boots with toe warmers
• a face-covering gaiter
• hand warmers in gloves and pockets

Soldier Field follows the NFL clear bag policy: one clear bag up to 12" x 6" x 12" plus a small clutch up to 4.5" x 6.5". Blankets are allowed if carried by hand or in an approved clear bag. For cold games the Bears have permitted battery-heated clothing (subject to screening), but they don't allow cardboard to stand on.

Theatre, dinner and business trips

Chicago is relaxed about dress. Dark jeans or trousers and a nice sweater work at most restaurants and theatres. Wear a thin merino base layer under your dress clothes, swap boots for shoes at the coat check if you like, and choose a long wool or down coat that looks good over a blazer. Several bars and restaurants set up heated igloos and rooftop pods in winter, and the same outfit works there with one extra layer.

Families with kids

Kids lose heat faster and complain sooner. Pack:

• waterproof mittens (easier than gloves for little hands)
• snow pants for snow play
• a spare base layer and socks in your daypack
• extra hand warmers

The CDC notes mittens are warmer than gloves. Plan short outdoor bursts between warm indoor stops. Our 1, 2 and 3-day Chicago itineraries group the indoor attractions so you can do exactly that.

What not to pack: common mistakes

• Cotton everything. Cotton hoodies and socks hold sweat and chill you. Choose wool or synthetics.
• A short or "fashion" coat. A hip-length wool peacoat isn't enough in January wind.
• Suede or canvas shoes. Salt and slush ruin them. Waterproof leather or rubber is the way to go.
• An umbrella as your main snow and rain defense. Wind between high-rises flips umbrellas. A hood works better.
• Too many outfits. Locals rewear their outer layers constantly. Pack fewer, better pieces.
• Earmuffs instead of a hat. You lose heat through the top of your head too.

Forgot something? Where to buy winter gear in Chicago

The Magnificent Mile and State Street have you covered:

• The North Face at 605 N. Michigan Ave.
• Uniqlo's new flagship at 600 N. Michigan Ave., good for HEATTECH base layers
• Macy's on State Street (111 N. State) and at 835 N. Michigan
• REI Lincoln Park at 905 W. Eastman St., a short ride from downtown, for serious boots, traction cleats and technical layers

Drugstores sell hand warmers and lip balm everywhere. Store inventory changes, so call ahead for specific sizes.

On brutal days in the Loop, use the Chicago Pedway. The City of Chicago describes this network of tunnels and bridges as linking more than 40 blocks over roughly five miles. It's open at least 7 a.m. to 5 p.m. on weekdays, with some segments open longer. A two-hour Pedway walking tour (4.7/5 from more than 300 reviews) is an easy way to learn the route on your first day.

Chicago winter packing FAQ

How cold does Chicago get in winter?

January is the coldest month, with a normal high of 31.6°F (–0.2°C) and low of 18.8°F (–7.3°C). Wind chills below 0°F happen most winters, and rare polar vortex outbreaks like January 2019 have pushed wind chills to –52°F.

Do I need snow boots for Chicago?

From December through February, yes: bring waterproof, insulated boots with good tread. In November and March, waterproof leather boots or water-resistant sneakers are usually enough, but check the forecast because early and late snow both happen.

Are jeans okay in Chicago in winter?

Yes. Jeans are fine for sightseeing, restaurants and theatre. On days in the 20s or colder, or for outdoor events, wear thermal leggings underneath, since denim alone gives little warmth against the wind.

Do I need thermal underwear?

For December to February trips, and for any outdoor event like a parade, market night or football game, yes. Lightweight merino base layers work for city days and won't overheat you indoors.

What should I wear to a Bears game in December?

Midweight base layers top and bottom, two mid layers, a long insulated parka, insulated boots with toe warmers, a hat, a neck gaiter, and mittens with hand warmers. Bring a blanket and use a clear bag no larger than 12" x 6" x 12".

What do I wear ice skating at Millennium Park?

Stretchy pants over thermals, a warm but not bulky jacket, waterproof gloves, a hat and tall wool socks. Reserve your session ahead online.

Should I bring an umbrella or a hood?

A hood. Chicago's wind makes umbrellas frustrating in winter. A water-resistant parka with an adjustable hood handles both snow and sleet.

Will my phone die faster in the cold?

Often, yes. Apple Support says iPhones are designed for temperatures of 32°F and above and may lose battery life temporarily, or shut off, in colder conditions. Keep your phone in an inside pocket and carry a power bank.

Final thoughts

Packing for a Chicago winter comes down to a coat that beats the wind, layers you can shed indoors, and boots that keep your feet dry through salt and slush. Get those right, add a hat, gloves, lip balm and a power bank, and you can enjoy the lights, markets and museums without being miserable.

Next, plan the days themselves with our Chicago itineraries, and compare attraction savings in our Chicago CityPASS and Go City comparison, because the pass you pick changes how much a cold-weather museum day costs.
