To jump in a large body of water with the way the weather has been over the past few weeks would be deemed as unwise or crazy. But those who decided to take a dive into the Chesapeake Bay Saturday had a cause: the Special Olympics Maryland.

The 15th annual Polar Bear Plunge took place on Jan. 30. People from all around Maryland and a few from other states took a dip in the bay as a part of a carnival-style outing that raises money for the Special Olympics Maryland. Compared to past overcast weather, this year’s plunge was considered mild, hitting a high of 33 degrees in and out of the water, according to an article in The Baltimore Sun.

“It’s totally fine, it’s a walk in the park compared to last year,” Colleen Dunn said in the article. “I still can’t feel my feet, but that’s OK.”

She was with 11 colleagues calling themselves the “Plunging Coconuts” wearing coconut shell bras, grass skirt and leis. The group raised $6,000 for the cause.

According to The Sun article, the event attracted an estimated 25,000 visitors — 12,000 of whom plunged — and raised $3 million for the Special Olympics.

The next fundraising event, according to the Special Olympics Maryland website, will be the Deep Creek Dunk, which will take place Feb. 26.
