The 10th parallel north is a circle of latitude that is 10 degrees north of the Earth's equatorial plane. It crosses Africa, the Indian Ocean, the Indian Subcontinent, Southeast Asia, the Pacific Ocean, Central America, South America, and the Atlantic Ocean.
At this latitude the sun is visible for 12 hours, 43 minutes during the summer solstice and 11 hours, 33 minutes during the winter solstice.[1]
On 21 June, the maximum altitude of the sun is 103.44 degrees and 56.56 degrees on 21 December. In this case an angle larger than 90° means that the culmination takes place at an maximum altitude of 76.56 degrees in the opposite cardinal direction. In the northern torrid zone, the Sun remains in the south during winter, but can reach over the zenith to the north in midsummer.
A section of the border between Guinea and Sierra Leone is defined by the parallel.
The Ten Degree Channel in the Indian Ocean is named after the parallel.
