A white Christmas refers to the presence of snow on Christmas Day. This phenomenon is most common in the northern countries of the Northern Hemisphere. Because December is in the middle of the Southern Hemisphere summer, white Christmases there are extremely rare, except in Antarctica, in the Southern Alps of New Zealand's South Island, and in parts of the Andes in South America.
