Circles of latitude between the 55th parallel south and the 80th parallel south

Following are circles of latitude between the 55th parallel south and the 80th parallel south. The 55th parallel south, crossing the southernmost point of Chile, is the last line of latitude moving southward to touch any part of any continent other than Antarctica, other than minor outlying islands.

The 56th parallel south is a circle of latitude that is 56 degrees south of the Earth's equatorial plane. No land lies on the parallel — it crosses nothing but ocean.

At this latitude the sun is visible for 17 hours, 37 minutes during the December solstice and 6 hours, 57 minutes during the June solstice.^[1]

Starting at the Prime Meridian and heading eastwards, the parallel 56° south passes through:

The 60th parallel south is a circle of latitude that is 60 degrees south of Earth's equatorial plane. No land lies on the parallel—it crosses nothing but ocean. The closest land is a group of rocks north of Coronation Island (Melson Rocks or Governor Islands) of the South Orkney Islands, which are about 54 km south of the parallel, and Thule Island and Cook Island of the South Sandwich Islands, which both are about 57 km north of the parallel (with Cook Island slightly closer).^[6]

The parallel marks the northern limit of the Southern Ocean (though some organisations and countries, notably Australia, have other definitions) and of the Antarctic Treaty System. It also marks the southern boundary of the South Pacific Nuclear-Weapon-Free Zone and the Latin American Nuclear-Weapon-Free Zone.

At this latitude the sun is visible for 18 hours, 52 minutes during the December solstice and 5 hours, 52 minutes during the June solstice. On December 21, the sun is at 53.44 degrees up in the sky and 6.56 degrees on June 21. The sun's altitude is exactly 30 degrees at either equinox.

The latitudes south of this parallel are often referred to as the Screaming 60s due to the prevailing high-speed, westerly winds which can generate large waves in excess of 15 m (50 ft) and peak wind speeds over 145 km/h (90 mph).^[7]

The maximum altitude of the Sun is > 15.00º in April and > 8.00º in May.

The lowest latitude where white nights can be observed is approximately on this parallel.

During the summer solstice, nighttime does not get beyond nautical twilight, a condition which lasts throughout the month of December. It is possible to view both astronomical dawn and dusk every day between February 17 and October 24.

The 67th parallel south is a circle of latitude that is 67 degrees south of the Earth's equatorial plane, about 50 km south of the Antarctic Circle. It crosses the Southern Ocean and Antarctica.

At this latitude the sun is visible for 24 hours, 0 minutes during the December solstice (Summer solstice) and 1 hour, 29 minutes during the June solstice (Winter solstice). If the latitude in the southern hemisphere is 67°45′ or smaller, every day of the month of September can view both astronomical dawn and astronomical dusk.

The 72nd parallel south is a circle of latitude that is 72 degrees south of the Earth's equatorial plane in the Antarctic. The parallel passes through the Southern Ocean and Antarctica.

This is the parallel where twilight/nighttime boundary on the equinoxes.

This is also the lowest parallel that golden hour occurs even at midnight sun, because the Sun is less than 6°00'00" above the horizon. Midnight sun without golden hour occurs at latitudes greater than 72°33'38.58804", i.e., about 666.8 km (414.3 mi) south of the Antarctic Circle in the case of the December Solstice.
