86° on Nov. 16, 1993, the hottest reading for this week of the year since 1933. Next is 85° in 1955.
Lydia’s center stands about 220 ft above sea level. Within three miles the land runs from 180 ft to 250 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Duplin Formation (sand, clay), from the Pliocene, 2.6 to 5.3 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 18 mi of the line.
Clay, sand. Age: Late Cretaceous, 66 to 72 million years old. About 4 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Lydia reaches the Atlantic Ocean by way of Sparrow Swamp, the Lynches, Clark Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lydia; river miles along the main stem, rounded.
Lydia has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 33° in January. About 47 inches of rain fall in a normal year.
On November 14 Lydia normally reaches 67° and falls to 40°. The record high is 81°, in 1989; the record low 22°, in 2013. The most rain on this date, 0.98 in, fell in 2016.
Normals 1991–2020 and records since 1933 at Bishopville 1.4 ENE, 7 miles southwest. NOAA, through RCC-ACIS.
