75° on Nov. 11, 2024, the hottest reading for this week of the year since 1924. Next is 72° in 1931.
South Congaree’s center stands about 190 ft above sea level. Within three miles the land runs from 160 ft to 380 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Sand Mountain, about 410 ft, 6 miles southeast.
Under the town center the state geologic map shows Cape Fear/Eutaw Formations (sand, gravel), from the Cretaceous, 66 to 145 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Cretaceous, 66 to 145 million years old. About 13 mi of the line.
Sand, gravel. Age: Cretaceous, 66 to 145 million years old. About 6 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Sand. Age: Late Cretaceous, 66 to 72 million years old. About 0.9 mi of the line.

A raindrop that lands in South Congaree reaches the Atlantic Ocean by way of Congaree Creek, the Congaree, the Santee and the South Santee: about 190 river miles.
Lake on the way: Lib Pines Lake.
70 miles of the trip are on the Santee.

South Congaree has a oceanic climate. Summer afternoons average 78° in July; winter nights fall to about 28° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 74 inches of water.
On November 14 South Congaree normally reaches 55° and falls to 38°. The record high is 72°, in 1931; the record low 16°, in 2019. The most rain on this date, 2.40 in, fell in 1961.
