Circles of latitude between the 35th parallel south and the 40th parallel south

, the 36th parallel south defines part of the border between Mendoza Province and La Pampa Province, and part of the border between San Luis Province and La Pampa Province. The 36th parallel south is a circle of latitude that is 36 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America. Around the world Starting at the Prime Meridian and heading eastwards, the parallel 36° south passes through: : ==37th parallel south==

The 37th parallel south is a circle of latitude that is 37 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America. This parallel approximates that latitude at which solar irradiance equals the planetary average, with higher insolation equatorward and lower poleward. An exploration of the 37th parallel south is the theme of Jules Verne's novel In Search of the Castaways. The phantom reef of Maria Theresa Reef is supposed to lie on this parallel in the Pacific Ocean. Around the world Starting at the Prime Meridian and heading eastwards, the parallel 37° south passes through: : ==38th parallel south==

The 38th parallel south is a circle of latitude that is 38 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, Australia, New Zealand, the Pacific Ocean, and South America, including the Andes Mountains and Patagonia. At this latitude the sun is visible for 14 hours, 48 minutes during the December solstice and 9 hours, 32 minutes during the June solstice. Around the world Starting at the Prime Meridian and heading eastwards, the parallel 38° south passes through: : ==39th parallel south==

The 39th parallel south is a circle of latitude that is 39 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America. Daylight along the 39th parallel south falls under 10 hours a day starting on 17 May and returns to over ten hours a day beginning 29 July. The growth of crops and other plants is considerably slowed during this period of reduced sunlight. Around the world Starting at the Prime Meridian and heading eastwards, the parallel 39° south passes through: : ==40th parallel south==

The 40th parallel south is a circle of latitude that is 40 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, Oceania, the Pacific Ocean and South America. Its long oceanic stretches are the northern domain of the Roaring Forties. On 21 June 2018, the sun is at 26.17° in the sky and at 73.83° on 21 December, in King Island, Tasmania, which is near the 40th parallel. The maximum altitude of the Sun is > 35.00º in April and > 28.00º in May. 40th parallel south also marks a line beyond which Andromeda constellation can no longer be observed.
