Meteorologists often define winter as the three calendar months with the lowest average temperatures. This corresponds to the months of December, January and February in the Northern Hemisphere, and June, July and August in the Southern Hemisphere.
Accumulations of snow and ice are commonly associated with winter in the Northern Hemisphere, due to the large land masses there. In the Southern Hemisphere, the more maritime climate and relative lack philippine phone number lookup of land south of 40°S makes winters milder; therefore, snow and ice are less common in the inhabited regions of the Southern Hemisphere. In this region, snow occurs every year in high-elevation regions such as the Andes, the Great Dividing Range in Australia, and the mountains of New Zealand, and also occurs in the southern Patagonian region of South America. Snow occurs year-round in Antarctica.
