Dear No Name Entered (I wonder who you are), The answer is because water holds more heat than land. Antarctica is a large continent roughly cenetered at the South Pole. At the North Pole, the equivalent area is occupied by the Arctic Ocean. When the summer sun shines on the ocean, it absorbs some heat, and ocean currents also bring in some heat from other regions of the oceans. The Arctic Ocean then realeases this heat through the darkness of winter, helping to moderate the climate, just as cities along the seacoasts generally have more moderate climates than cities in the interior of continents.
