Special Olympics Wisconsin: The anchor of polar plunging

The Special Olympics Wisconsin Polar Plunge series represents the state's largest organized plunge network, now entering its 27th year. These events raised nearly $1.1 million in 2024-2025 while supporting 14,000+ athletes who train and compete in 19 Olympic-style sports.

What sets SOWI plunges apart is their professional organization: every event features law enforcement officers and firefighters in wetsuits standing in the water, heated changing facilities, live entertainment, and food vendors. The $100 minimum fundraising requirement ensures meaningful impact while earning participants the year's commemorative long-sleeve shirt.

Five in-person events for 2026

Special Olympics Wisconsin has confirmed five in-person Polar Plunge locations for 2026 (slightly reduced from eight in 2025), plus their D.I.Y. Alternative Plunge option for those who prefer creating their own cold adventure at home.

Oshkosh Fox Valley Plunge (Menominee Park, early February) consistently draws the largest crowds—1,700 plungers have raised $444,000 in peak years. Participants jump into Lake Winnebago, one of Wisconsin's largest natural inland lakes, with pre-event activities including a 5K run and wing-eating contest.

Madison Polar Plunge (Lottes Park, mid-February) serves as the flagship southern Wisconsin event. Nearly 600 participants enter the Yahara River at Monona each year, making it the capital city's signature winter charity moment. Registration opens at 9:30 AM with opening ceremonies around 10:45 AM.

La Crosse Polar Plunge (Black River Beach, March 1) holds special historical significance as Wisconsin's original Polar Plunge, launched in 1998. The 27-year tradition includes a unique feature: DJ TDogg lets each plunger pick their entry song. Shuttles run from downtown bars starting at 8:30 AM, creating a full-day celebration.

Green Bay Polar Plunge (Perkofski Boat Launch, late February) sends participants into the Fox River near De Pere. Past events have attracted 485 plungers raising $132,000, with strong support from Packers-loving teams in elaborate costumes.

Chippewa Falls Polar Plunge (Loopy's Grill & Saloon, early March) offers a uniquely convenient setup—the bar and restaurant venue means participants can walk directly from icy Chippewa River water into immediate indoor warmth. Expect 200-300 plungers and shuttle service from overflow parking.

The inclusive plunge revolution

The Whitewater Inclusive Plunge (Whitewater Aquatic Center, mid-March) launched in 2024 as the nation's first ADA-compliant Polar Plunge. Using a ramp-entry lap pool rather than open water, this event welcomes participants with mobility limitations who couldn't safely access traditional lake plunges. For families with members who use wheelchairs or have physical challenges, this event represents a breakthrough in inclusive winter experiences.

Family age requirements for SOWI events

• Under 12: Not eligible to plunge

• Ages 12-15: May plunge with parent/guardian present

• Under 18: Parent must sign waiver during registration

• All ages: Welcome as spectators and cheerleaders

Register at PlungeWI.org with donations accepted until March 22, 2026.

New Year's Day plunges across Wisconsin

For families wanting to start 2026 with an unforgettable adventure, Wisconsin offers more free community plunges on January 1 than perhaps any other Midwestern state.

Jacksonport celebrates 40 years in Door County

The Jacksonport Polar Bear Plunge enters its 40th year in 2026, making it Wisconsin's longest-running New Year's Day tradition. The origin story is pure Wisconsin: in 1986, 14-year-old J.R. Jarosh lost a 5-mile running bet to his father and had to swim in Lake Michigan as penalty. That single swim spawned four decades of tradition.

Today, 500-800 swimmers charge into frigid Lake Michigan waters at noon sharp while thousands of spectators line Lakeside Park. The event has been featured in Subway commercials, the movie "Feed the Fish," and Guinness TV advertisements. Participants come from dozens of states and multiple countries—a 2017 event drew nearly 900 swimmers.

Registration opens at 10:30 AM at Lakeside Park, with the plunge at noon sharp, Central Time. It's completely free with proceeds benefiting the Jacksonport Fire Department. Fifteen firefighters staff the event both on shore and in the water. Every participant receives a free certificate. No reservation required—just show up, sign a waiver, and jump.

Family planning note: This event's size, safety infrastructure, and spectator-friendly setup make it ideal for families where some members plunge while others cheer from shore. Nearby Mike's Port Pub and JJ's of Jacksonport offer warming options afterward.

Milwaukee's Bradford Beach tradition

The Milwaukee Polar Bear Plunge at Bradford Beach represents the Milwaukee metro's oldest New Year's tradition, dating to the 1970s. Unlike organized charity events, Bradford Beach operates as a free, community-driven gathering with no official organizer—just hundreds of hardy souls converging at noon.

The Milwaukee Fire Department Dive Rescue Team provides water safety, and the beach typically features music and festivities. The Milwaukee Barbarians Rugby Club hosts pre and post-plunge gatherings at Dugout 54, creating a warm social hub for participants.

Important logistics: Parking is extremely limited—arrive early. There are no enclosed changing facilities, so bring your own towels, robes, and a plan for modesty. The rocky Lake Michigan bottom requires sturdy footwear you can get wet.

Southeast Wisconsin's family-friendly options

Shorewood's Atwater Beach Plunge (organized by the Gentlemen of Shorewood) offers a unique combination: the noon plunge is followed by a chili cookoff at participating local restaurants competing for the "Golden Spoon" award. Hot coffee is provided on the beach. The observation deck above Atwater Park provides excellent spectator viewing.

The Kenosha Polar Bear Plunge at Simmons Island carries a tradition dating to 1965, organized by Diver Dan's Scuba Center with the Scout Leaders Rescue Squad providing water safety. The 11 AM plunge is free with donations accepted for the rescue squad. Attendance varies from 10 to 400+ depending on weather—if waves or undertow are dangerous, organizers cancel.

Racine's Splash and Dash combines a 5K run ($25) starting at 10:30 AM with a noon polar plunge, all benefiting four local charities: Racine County Food Bank, HALO homeless assistance, the Hospitality Center, and Kiwanis scholarships. The Racine Yacht Club opens to the public, letting spectators watch from warm windows. This is the 34th+ annual event.

Lake Geneva area splashes

The Geneva Lake Community Plunge at Williams Bay Beach has grown to 100+ participants in recent years. The Lady of the Lake tour boat provides the countdown, and costumes range from wetsuits to swimsuits to full character outfits. Hot dogs, hot chocolate, and tailgating create a festive atmosphere.

Unique spectator option: Lake Geneva Cruise Line offers a free Polar Plunge Viewing Tour departing at 11:30 AM from Williams Bay. Watch from a heated boat while plungers take their icy dip. Donations to the 531 Fund are encouraged.

The nearby Dip for Dave at The Boat House Bar & Grill supports Kisses from Keegan & Friends, a pediatric cancer foundation. Named for Dave Mikrut, a beloved charity board member who passed away in 2021, this intimate event raises approximately $2,000 annually for kids fighting cancer.

Northwoods and central Wisconsin adventures

Pickerel's delightfully quirky tradition

The Jerry Schuh's Pickerel Polar Bear Jump-In at Schuh's Sportsmen's Lodge embodies everything wonderful about small-town Wisconsin winter culture. Scheduled for the second Saturday of February (February 14, 2026), the 1 PM plunge into Pickerel Lake features amenities you won't find anywhere else: couches and recliners dragged onto the frozen lake for spectators, a food tent on the ice, and a pine-tree-surrounded setting that feels like stepping into a Northwoods postcard.

The event is completely free with "thousands" of spectators attending to watch the community tradition. The same day features a Pickerel EMS Pancake Breakfast (8-11 AM) and the Tombstone-Pickerel Sno Club Chili Ride-In for snowmobilers.

Wisconsin Rapids and the fun extras

The Wisconsin Rapids Polar Plunge at Anchor Bay Bar & Grill kicks off February with more than just cold water—the event includes a Freezin' For a Reason 5K, a snowshoe walk, a wing-eating challenge, and appearances by Miss Wisconsin Rapids. The man-made plunge pool allows controlled water depth for safer jumping. This location has raised $94,000+ in peak years.

Southern Wisconsin options beyond Madison

Lee Lake's quarter-century cancer fight

The Lee Lake Polar Plunge in tiny Cazenovia (Richland County) celebrates its 25th anniversary on February 22, 2026. This intimate event draws approximately 50 jumpers who raise funds for cancer research through the Greater Richland Area Cancer Elimination.

What makes Lee Lake special is the all-day community gathering: activities begin at 11 AM at the Cazenovia Community Center with silent auction, bake sale, live auction, food, and raffles before the 2 PM plunge at the boat ramp. The event has raised approximately $350,000 over its history. Contact Terri Benning at 608-983-2397 for registration details.

Essential family preparation guide

What to pack for the plunge

For the plunge itself:

• Swimsuit or athletic quick-dry clothing

• Closed-toe water shoes (required at most events—lake bottoms are rocky or muddy)

• Optional swim cap to retain heat

• Lightweight, easy-to-remove costume if desired

For warming up:

• Fluffy bathrobe for before and immediately after

• Loose-fitting layers without complicated buttons or zippers (numb fingers struggle)

• Thick wool socks and slip-on shoes for post-plunge

• Hat and gloves for spectating

Supplies to bring:

• At least 2-3 large towels

• Blanket (to stand on—frozen ground hurts bare feet)

• Plastic bag for wet clothes

• Hand and toe warmers

• Complete change of dry clothes including underwear

• Thermos with warm (not hot) beverages

Critical safety considerations

Who should NOT plunge: The American Heart Association warns that people with heart conditions, high blood pressure, respiratory issues, or those taking beta blockers should avoid cold water immersion. Individuals with low body weight or low body fat cool faster and face higher hypothermia risk. Always consult your doctor if you have any health concerns.

Cold shock is real: The National Center for Cold Water Safety warns that sudden immersion in water under 60°F can trigger an involuntary gasp reflex that causes drowning if your head is underwater. Always enter slowly, keep your head above water, and never dive in.

How long to stay in: Medical experts recommend limiting exposure to 1-2 minutes for first-timers, with an absolute maximum of 15 minutes. Most polar plunge events are designed as quick "get in, get out" experiences at waist depth.

Watch for hypothermia signs: Violent shivering, slurred speech, confusion, and pale skin indicate mild hypothermia. If shivering stops while someone still feels cold, that indicates progression to moderate hypothermia requiring immediate medical attention.

The crucial post-plunge warmup

Warm up gradually—this is counterintuitive but critical. The "afterdrop" phenomenon means your core temperature continues dropping for several minutes after you exit cold water as chilled blood from your extremities circulates back to your core. Jumping immediately into a hot shower can cause dangerous blood pressure changes.

Proper recovery sequence:

1. Exit slowly and dry off immediately

2. Cover extremities first (feet and head)

3. Put on loose, dry clothing in layers

4. Stay sheltered from wind

5. Allow natural rewarming for 15-30 minutes

6. Sip warm (not hot) beverages gradually

7. Wait at least 30 minutes before hot showers, starting lukewarm

Making it a positive family experience

For children ages 12-15 at Special Olympics events, or any age at free community plunges, success depends on framing. Never pressure reluctant kids—fear of cold water is natural and healthy. Instead:

• Let children choose their role: plunger, cheerleader, towel holder, photographer

• Create team costumes that build excitement

• Discuss the charitable cause (Special Olympics athletes, cancer research)

• Plan a special post-plunge celebration meal

• Take photos and share on social media to reinforce the accomplishment

For families with younger children who can't plunge, the Alternative Plunge option lets you create your own cold adventure at home: a bucket of ice water, a backyard kiddie pool in December, or water balloons in cold weather. Kids still participate in fundraising and can watch the real event on social media with the #PlungeWI hashtag.

Wisconsin water reality check

Lake Michigan water temperature in January-March ranges from 32-39°F—essentially ice water. February averages around 37°F while March often drops to 33°F as winter's cold fully penetrates the lake. Inland lakes are frequently frozen solid, with organizers cutting holes for plungers. Air temperatures on event days can range from -10°F to 30°F depending on conditions.

Every organized event in Wisconsin features professional safety personnel. Special Olympics events have law enforcement and firefighters in wetsuits standing in the water. The Jacksonport Fire Department deploys 15+ firefighters on land and water. Community events typically have dive rescue teams present.

Why Wisconsin families keep coming back

Beyond the adrenaline and bragging rights, polar plunging creates something increasingly rare: shared physical challenges that bond families across generations. A 13-year-old and a 63-year-old experience the same shock, the same triumph, the same ridiculous joy of running back to shore. Teams like Neenah's "Waldos" have plunged together since 2002, raising $25,000+ annually while creating decades of family memories.

The charitable impact compounds that meaning. Special Olympics Wisconsin athletes don't just receive funding—they gain 14,000+ teammates who literally freeze alongside them each winter. The Lee Lake Plunge's $350,000 lifetime total represents countless cancer patients supported by a community of 50 annual jumpers in a tiny town most Wisconsinites can't find on a map.

For 2025-2026, your family has more options than ever: the massive community energy of Jacksonport's 40th anniversary, the accessible revolution of Whitewater's inclusive plunge, the historical significance of La Crosse's original event, or the quirky charm of Pickerel's couches-on-the-ice tradition.

The water's cold everywhere. The warmth comes from jumping together.
