Perry’s center stands about 480 ft above sea level. Within three miles the land runs from 320 ft to 500 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Huber/Lisbon/Barnwell Formations, undivided (clay, sand), from the Eocene, 34 to 56 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 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sand. Age: Eocene, 34 to 56 million years old. About 15 mi of the line.
Clay, sand. Age: Tertiary, 2.6 to 66 million years old. About 6 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Perry reaches the Atlantic Ocean by way of Jordan Creek, Dean Swamp Creek, the South Fork Edisto, the Edisto and the North Edisto: about 180 river miles.
100 miles of the trip are on the Edisto.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Perry; river miles along the main stem, rounded.
Perry has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 34° in January. About 52 inches of rain fall in a normal year.
On November 14 Perry normally reaches 69° and falls to 41°. The record high is 81°, in 1999; the record low 16°, in 2013. The most rain on this date, 2.32 in, fell in 2008.
