Patrick’s center stands about 230 ft above sea level. Within three miles the land runs from 170 ft to 390 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is King Sand Hills, about 590 ft, 11 miles west.
Under the town center the state geologic map shows Peedee Formation - Black Creek Group, undivided (clay, sand), from the Late Cretaceous, 66 to 72 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 49×. 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: Late Cretaceous, 66 to 72 million years old. About 21 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sand, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 1 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Patrick reaches the Atlantic Ocean by way of Juniper Creek, Thompson Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 180 river miles.
150 miles of the trip are on the Great Pee Dee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Patrick; river miles along the main stem, rounded.
Patrick has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 32° in January. About 48 inches of rain fall in a normal year.
On November 14 Patrick normally reaches 66° and falls to 40°. The record high is 82°, in 1951; the record low 22°, in 2013. The most rain on this date, 0.72 in, fell in 1997.
