What is a polar plunge?

A polar plunge is simple: participants jump into the frigid waters of Lake Michigan, while raising money to support local families in need.

When is the next plunge?

Who is the Chicago Polar Bear Club?

The Chicago Polar Bear Club (CPBC) is grassroots 501(c)(3) non-profit organization, based in Chicago, dedicated to helping real Chicagoland families. The CPBC holds an annual “polar plunge” event each January to raise money to support a select set of families, who need help to cover medical expenses, find a safe home, care for extended family, etc.

How old do you need to be to take the plunge?

All ages are welcome to join us for our plunge, but participants under 18 years old must have a parent or legal guardian give consent and agree to the waiver.

This is my first time taking the plunge, what should I expect?

Expect to have a great time with hundreds of other plunge’rs! The plunge is a quick dip into Lake Michigan (no diving permitted), followed by a quick dry off. Then join us immediately following the plunge at our after party to celebrate with drinks, food, pictures of the plunge, win raffle prizes, and more!

Can I plunge with a group?

Absolutely! Plunge’ing with a group of friends, family, classmates, or coworkers is a great way to check an item off your bucket list while raising money for a great cause. You can register individually or together on our website. (If you are planning to plunge with a group of 10 or more, contact us for special group rates!)

When do we jump into the water and “take the plunge”?

We plunge at 12noon sharp, but please arrive at the beach by 11:30am to check-in, visit our sponsor booths, buy some plunge merchandise, listen to music, and mingle with the hundreds of other plunge’rs!

Do I need anything special to plunge?

Please come to the beach with the following in order to take the plunge: Your signed waiver (unless you signed online), Closed toed shoes (required for taking the plunge itself), a towel, warm clothes (layers are best), and your best plunge costume (highly encouraged - have fun with it!)

Is there any charge to get into the event as a spectator or supporter?

Nope! Spectators and supporters are welcome to join us to watch the plunge and cheer on participants, free of charge.
