Quick Facts about Antarctic Circle

The Antarctic Circle is one of the five major circles of latitude that mark maps of the Earth. It is the parallel of latitude at 66° 33′ 39″ south of the Equator, crossing mostly the Southern Ocean. The continent of Antarctica is most of the area within the Antarctic Circle. This line of latitude was first crossed by Captain James Cook on January 17, 1773.

In the Antarctic Circle, all places have twenty-four hours of daylight on the Summer Solstice in December. In June on the Winter Solstice all places have twenty-four hours of night. There is a minimum of one whole day that the sun does not set and one whole day that the sun does not rise south of the Circle.

There is no permanent population of persons in the Antarctic Circle. Antarctica is the driest, coldest, and windiest continent on Earth. The lowest temperature ever recorded on earth was in Antarctica, i.e. −89.2 °C (−128.6 °F).
