25th Polar Plunge Chicago set for Sunday at North Avenue Beach to benefit Special Olympics Illinois

Thousands of brave people will embrace the frigid winter waters of Lake Michigan by jumping in Sunday for the 25th Polar Plunge Chicago. About 5,000 people are expected to take the plunge at North Avenue Beach, with air temperatures in the 20s and water temperatures in about the mid-30s — actually not too bad compared to some past years. Polar Plunge Chicago is presented by Special Children’s Charities, with a goal of raising $2 million for Special Olympics Illinois. As of 8 a.m. Sunday, the goal was 83% reached, with just over $1.66 million raised.
