Mooresboro’s center stands about 900 ft above sea level. Within three miles the land runs from 760 ft to 990 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Lisenberry Mountain, about 1,910 ft, 15 miles north.

A raindrop that lands in Mooresboro reaches the Atlantic Ocean by way of Sandy Run, the Broad, the Congaree, the Santee and the South Santee: about 310 river miles.
Lake on the way: Lib Pines Lake.
110 miles of the trip are on the Broad.

Mooresboro has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 27° in January. About 50 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Mooresboro normally reaches 64° and falls to 35°. The record high is 81°, in 1955; the record low 18°, in 2019. The most rain on this date, 1.88 in, fell in 1972.
