45th Parallel South

Line across the Earth
45°
45th parallel south

The 45th parallel south is a circle of latitude that is 45 degrees south of the Earth's equatorial plane.

Highway sign marking the 45th parallel in New Zealand.
It is the line that marks the theoretical halfway point between the equator and the South Pole. (The true halfway point is 16.2 kilometres (10.1 mi) south of this parallel because the Earth is not a perfect sphere but bulges at the equator and is flattened at the poles.[1])

Unlike its northern counterpart it passes mostly over open ocean. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America.

At this latitude the sun is visible for 15 hours, 37 minutes during the December solstice and 8 hours, 46 minutes during the June solstice.
