The 53rd parallel south is a circle of latitude that is 53 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.
At this latitude the sun is visible for 16 hours, 56 minutes during the December solstice and 7 hours, 34 minutes during the June solstice. Approximately 53º18' South, 33 km (21 mi) south of this parallel, during the December summer solstice, the sun is visible for 17 hours exactly. If the latitude in the southern hemisphere is 53º47' or smaller, it is possible to view both astronomical dawn and dusk every day of the month of February.[1]
