CHICAGO (WLS) — As dawn breaks each day, irrespective of the season, a man affectionately dubbed “The Great Lake Jumper” makes his way to Lake Michigan for a brisk swim. His dedication to this daily ritual is unwavering, come rain or shine, or even freezing temperatures.

It’s important to note that such daring feats, especially on frigid days like last Friday, are not for the faint-hearted or recommended for the average person. Yet, his story has captured attention and intrigue.

ABC7 took a closer look at his remarkable commitment to this routine and uncovered the reasons behind his devotion. Astonishingly, he has not missed a single dip in over five years, defying the elements with steadfast consistency.

The Chicago region is currently facing an Extreme Cold Warning, with a Cold Weather Advisory in effect from noon Friday through 9 a.m. Saturday. Despite the biting chill, this hasn’t deterred the bold swimmer or others who ventured into the icy waters on Friday morning.

Extreme cold or not, ABC7 saw some folks were taking a plunge of their own on Friday morning.

Four people jumped or eased into Lake Michigan. One of them was Dan O’Connor, who has been jumping into the lake each day for several years.

It is a ritual that’s been going on for years and one that subzero temperatures didn’t stop as Chicago’s Great Lake Jumper took his daily plunge into Lake Michigan.

Like clockwork, O’Connor was flipping into Lake Michigan.

“It’s become part of my routine,” O’Connor said. “Wake up, have a cup of coffee and drive to the lake and jump in.”

The 58-year old husband and father has now leapt into Lake Michigan at Montrose Harbor every morning for the past five and a half. Even with Friday’s icy waters, it was no different.

“Today for as bad as the temperature is and for as low as the temperature is, it wasn’t bad there wasn’t much ice buildup,” O’Connor said. “I really didn’t have to chop ice today.”

Even with subzero temperatures, he took the plunge and so did four others while several people watched.

“We’re still Chicagoans, and Chicagoans are built different,” O’Connor said.

O’Connor says his “addictive” dunk into lake waters began during the COVID-19 pandemic on June 13, 2020 after his wife gave him a friendly suggestion about how to cure his hangover.

“And like a good husband I listen to my wife,” O’Connor said. “She told me to go jump at the lake and I did.”

Despite the holidays, family gatherings, and life’s other commitments, the Lincoln Square neighborhood resident has managed to keep his streak going. He’s made 2,049 jumps so far.

The jumps have made him a bit of a local celebrity and a favorite on social media. While he says Friday’s jump got around 200,000 views in just two hours, he maintains his dives are about inner peace.

“It’s something positive and I love the internal rush that I get and it’s an amazing feeling,” O’Connor said.

He says he’s never been hurt during his jumps and always tries to be as safe possible, even keeping a sledgehammer handy to break up ice if necessary.

“We’ve got this great lake and and it’s right here on our doorstep in Chicago and it’s there to use and I’m using it,” O’Connor said.

One question is how long will O’Connor continue to jump in the lake. He says until he can’t.

Frostbite risk

Dr. Joshua Sherman from Advocate Health Care joined ABC7 on Friday morning.

The temperatures could cause frostbite on exposed skin in as little as 10 minutes.

“It’s really important they wear a number of layers, staying very warm, but also staying very dry. Making sure you’re also not wearing anything very, very tight that restricts any blood flow,” Endeavor Health Elmhurst Hospital Dr. Ameer Sharifzadeh said. “If you start to feel any kind of tingling or numbness, any a lot of pain, absolutely get indoors, make sure you’re getting warm.”
