The 30th parallel south is a circle of latitude that is 30 degrees south of the Earth's equator.It stands one-third of the way between the equator and the South Pole and crosses Africa, the Indian Ocean, Australia, the Pacific Ocean, South America and the Atlantic Ocean.
The meridian 60° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Greenland, North America, the Atlantic Ocean, South America, the Southern Ocean, and Antarctica to the South Pole. The mean solar time of this meridian is the base for the Atlantic Time Zone (UTC-4 during standard time).
On 21 June, the maximum altitude of the sun is 83.44 degrees and 36.56 degrees on 21 December. [citation needed] At this latitude: One degree of longitude = 96.49 km or 59.95 mi; One minute of longitude = 1.61 km or 1.00 mi; One second of longitude = 26.80 m or 87.93 ft

With this value for R the meridian length of 1 degree of latitude on the sphere is 111.2 km (69.1 statute miles) (60.0 nautical miles). The length of one minute of latitude is 1.853 km (1.151 statute miles) (1.00 nautical miles), while the length of 1 second of latitude is 30.8 m or 101 feet (see nautical mile).
At 30° a longitudinal second is 26.76 m, at Greenwich (51°28′38″N) 19.22 m, and at 60° it is 15.42 m. On the WGS 84 spheroid, the length in meters of a degree of latitude at latitude ϕ (that is, the number of meters you would have to travel along a north–south line to move 1 degree in latitude, when at latitude ϕ), is about
The meridian 30° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Europe, Turkey, Africa, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole. The 30th meridian east forms a great circle with the 150th meridian west. The meridian is the mid point of Eastern European Time.
