Brave souls will be plunging into the new year with a frosty dip in the Atlantic today. The Herring Cove Polar Bear Dip has drawn about 200 people into Halifax Harbour in recent years. This year Halifax Water has taken precautions to assure swimmers the harbour is safe to enter. The utility turned its ultraviolet lights back on to ensure bacteria levels in the harbour are within swimming guidelines. The Icy swim gets underway at noon.
