St. Patrick's Day river dyeing, Cubs and White Sox opening day, Chicago Architecture Biennial, restaurant week
Chicago is a four-season city — each one has its moment. Here's what to expect and how to plan.
Chicago has real seasons — and they each completely change the personality of the city. Summer is festival-loud and lakefront-bright. Fall is golden and crisp. Winter is moody and atmospheric. Spring is hopeful and underrated. Pick the experience you want first, then plan around the weather.

St. Patrick's Day river dyeing, Cubs and White Sox opening day, Chicago Architecture Biennial, restaurant week
Cherry blossoms in Jackson Park, lakefront walks, museum days, first patio dinners
Shoulder-season hotel rates; book a flexible coat. Lakefront wind can drop temperatures 10°F instantly.

Lollapalooza (Aug), Pitchfork Festival, Taste of Chicago, Chicago Air & Water Show, Pride Parade, neighborhood street fests every weekend

Peak prices. Book hotels 2–3 months out, more for Lollapalooza weekend. Bring sunscreen — lakefront sun is intense.
Weather: Crisp and dry — 70°F in September dropping to 45°F by mid-November. Arguably the city's most photogenic season.
Chicago Marathon (October), Chicago International Film Festival, Open House Chicago architecture weekend, Halloween in Lincoln Park Zoo
Foliage along the river, Cubs/Bears overlap, food and wine festivals, last patio season, museum-and-jazz double headers
September has summer weather with shoulder pricing — the sweet spot. Book a light jacket for evenings.
Weather: Cold and snowy — 16–35°F is normal, with windchills that can bite. Lake-effect snow rolls through in waves.
Christkindlmarket at Daley Plaza, Lights Festival on Michigan Ave, Magnificent Mile Lights Parade, ice skating at Millennium Park & Maggie Daley
Museum afternoons, deep-dish dinners, jazz at the Green Mill, cozy speakeasies, snowy skyline photos from the lakefront
Cheapest hotel rates of the year (especially mid-Jan to Feb). Pack a real winter coat, gloves, and waterproof boots — lakefront wind is no joke.
Grant Park — Chicago's seasonal event hub
Mid-January through late February (after the holidays) and early November have the lowest hotel rates. You'll trade some warmth for great deals on otherwise-expensive downtown hotels.
Late May through mid-October. June and September are arguably the sweet spots — warm but not humid, and shoulder pricing on hotels.
Absolutely. Christkindlmarket, ice skating at Maggie Daley and Millennium Park, snowy skyline photos, and cozy jazz clubs make winter one of the city's most atmospheric seasons — pack a real coat.
First weekend of August in Grant Park. Hotels sell out months in advance and prices spike across the city.
