Around the coasts of Antarctica, temperatures are generally close to freezing in the summer (December-February) months, or even slightly positive in the northern part of the Antarctic Peninsula.

During winter, monthly mean temperatures at coastal stations are between -10°C and -30°C but temperatures may briefly rise towards freezing when winter storms bring warm air towards the Antarctic coast.

Conditions on the high interior plateau are much colder as a result of its higher elevation, higher latitude and greater distance from the ocean. Here, summer temperatures struggle to get above -20°C and monthly means fall below -60°C in winter. Vostok station holds the record for the lowest ever temperature recorded at the surface of the Earth (-89.2°C).
