St. Patrick's Day Party Planning in Chicago: Weekend and March 17

St. Patrick's Day in Chicago is not a single day. Parades, the green river and bar crowds fill the weekend around March 17, and it can be one of the busiest party weekends of the early spring. If you host a party, you need to plan around the date, the cold and the crowds. This guide covers the choices that matter most. For general March tips, see planning an event in Chicago in March.

Pick the date

The river is usually dyed green on the Saturday before March 17, and the main parades follow the same weekend. In 2027, March 17 falls on a Wednesday, so the Saturday before is March 13. Check the city's event calendar for this year's exact dates and street closures.

A Saturday party is the easiest because guests are off work. A Wednesday party works best as a short after-work event. If you want the crowd, host on the weekend. If you want quiet, host on a different weekend, or on the day itself.

Indoor or patio

Indoors. A bar, a hall, a garage with heat or a living room. Easy for weather and for guests, but limited on space. See garage party layout ideas.

Patio. A patio gives you room, but March in Chicago can mean snow, wind and cold. Patio heaters and a tent make it work. See how many patio heaters you need and tent heater vs patio heater. Heaters need fuel, and the fuel may not be included in the rental, so ask.

Standing tables and space

A St. Patrick's party is usually a stand-and-drink party. Cocktail tables fit more people than seated tables.

• Rule of thumb. About 8 to 10 square feet per guest for a standing party, and one 30-inch cocktail table for every 6 to 8 guests.
• Seating. A few lounge spots or chairs along a wall for older guests.
• Flow. Put the bar, food and tables apart so people move around.

March weather and what to ask for

March in Chicago swings. One weekend is snow and wind off the lake, the next is mild enough to stand outside with a jacket. You will not know which until a few days before, so book the backup when you book the main plan. If you want the patio, ask for a tent with sidewalls and heaters at the same time, and ask what happens to the order if you move inside. Rental companies handle date changes differently, so read the terms in event rental cancellation and date change policy before you pay.

Lighting matters too. Sunset is around the time guests arrive for an early evening party, and string lights or lanterns help a patio feel finished. See winter event lighting for how early it gets dark, and keep cords off walkways.

Food, drinks and decor

Keep it simple: a buffet table with hot dishes, a bar, and plenty of ice. Green and gold linens, a runner and a few signs carry the theme. If you serve alcohol, check Illinois alcohol rules for private events. Add a non-alcohol drink station for everyone else.

Getting there and parking

Downtown is busy on St. Patrick's weekend. Streets near the river and parade routes close, buses are crowded and parking is hard.

See guest parking and transit tips for the full checklist.

What most hosts find out too late

• Delivery is harder on parade weekends. Rental trucks need a clear street, and downtown closures can move the delivery window. Ask about timing and have a loading spot ready.
• Book early. It is a busy date for bars and venues, and rentals fill up. Check the date first.
• Heaters need fuel. Ask whether propane is included, and who changes the tank.
• Count at delivery. Check glasses, tables and heaters against the quote.
