The Venice Beach Penguin Club invites all brave souls to take a New Year's Day dip at its 59th annual Wintertime Swim at the Venice Beach breakwater. (North of Venice Blvd., south of Windward Ave.) The SoCal version of the annual New Year's Day ritual might not require the thick skin of, say, those who take the plunge in New England, but it could be pretty darn chilly in Venice if El Niño turns up on schedule.
On site sign-ups begin at 11am. The swimming starts at noon (and ends fairly quickly thereafter). Spectators are welcome.
Note a few other SoCal locations have similar plunges.
