Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, due to tidal forces resulting from the orbit of the Moon. On July 2, 2018 it was at approximately 66° 33' 47.2" north of the Equator. Any locations falling south of this latitude are said to be in the Antarctic Circle. The Arctic Circle lies parallel to the Equator, and is approximately 66.5°* north of the Equator. In the interior, summers can be quite warm, while winters are extremely cold.
