Roughly 4,000 people decided to jump into the icy Atlantic Ocean water for what’s been an annual tradition for more than a century.

And it was the perfect day for a swim — if your ideal water temperature is roughly 39 degrees.

“It was cold but we’re here,” said participant Randy Goldbaum. “Happy New Year, New York!”

The average person might even call it crazy.

“I’m a little bit crazy but thats ok,” said Valerie Greco of Staten Island. “I’m living. We’re living. This is life!”

But you might not call these your average people.

“I first did this in 2017,” said participant Dylan Fried. “I did it again last year, now this year, and probably doing it again next year. I don’t care how crazy that makes me sound.”

It’s all for the annual Coney Island Polar Bear Club’s New Year’s Day Polar Plunge.  

“I am 60 years old, but when I jump in that water I feel like I am ten years old,” said participant Carlos Planas.

Those who do it say the rush of adrenaline and endorphins is the best way to start a new year with a clean slate.

“[You] get rid of all the old stuff and bring in the new,” said participant Joel Sklar.

“Today is just a very good way to kind of reset everything,” said Fried.

“You do it, you ring in the new year, take all the bad luck with you, leave it in the ocean, and thats it,” said participant Dianne Rodriguez.

People do this not just for a frigid jolt of winter invigoration, but this annual event helps raise funds for local organizations in Coney Island, including the Coney Island YMCA, the New York Aquarium, and the Alliance for Coney Island.

“I feel revived,” said participant Nysheika Gilchrist. “Refreshed. New Year. New beginnings, blessings, I’m here.”
