What and When is Winter - exactly?  Meteorological winter is the season having the shortest days and the lowest average temperatures, which have the coldest weather. This corresponds to the months of December, January and February in the Northern Hemisphere, and June, July and August in the Southern Hemisphere. The coldest average temperatures of the season are typically experienced in January in the Northern hemisphere and in June or July in the Southern hemisphere.

Astronomically, the winter solstice, being the day of the year which has fewest hours of daylight, ought to be the middle of the season, but seasonal lag means that the coldest period normally follows the solstice by a few weeks. In the USA (and sometimes in Britain) the season is regarded as beginning at the solstice and ending on the following equinox — in the Northern Hemisphere, depending on the year, this corresponds to the period between 21 or 22 December and 20 or 21 March.
