A white Christmas, to most people in the Northern Hemisphere, refers to snowy weather on Christmas Day, a phenomenon which is far more common in some countries than in others. For example, in many parts of the USA, snow is seldom experienced at Christmas except in the mountains; but most parts of Canada except for the British Columbia coast and southern interior valleys, southern Alberta, southern Ontario and parts of the Maritimes stand an excellent chance of experiencing a white Christmas. The same goes for the countries in northern Europe, such as ones in Scandinavia, the Baltic States, northern Russia, Belarus.
