The St. Louis Blues defeated the Minnesota Wild 6-4 Saturday night in the 2022 National Hockey League (NHL) Winter Classic at Target Field in Minneapolis, Minnesota, officially ruled the coldest outdoor game in league history.

The temperature was -6 degrees at puck drop, sinking to -10 as the game went on, according to the NHL with a wind chill in the negative 20s.

Before tonight’s game, the coldest game in league history was during the 2003 Heritage Classic, the first outdoor game, between the Edmonton Oilers and Montreal Canadiens at Commonwealth Stadium in Edmonton. It was zero degrees at puck drop.

Prior to the game, the NHL said the ice will need to be heated: “When the air temperature is above the optimum ice temperature, the glycol and aluminum pans transfer heat away from the ice. But when the air temperature is below the optimum ice temperature, it transfers heat to the ice,” said
