75° on Nov. 11, 2024, the hottest reading for this week of the year since 1924. Next is 72° in 1931.
Hopkins’s center stands about 190 ft above sea level. Within three miles the land runs from 130 ft to 270 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Sand Mountain, about 410 ft, 11 miles west-southwest.
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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. 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 6 mi of the line.
Clay, sand. Age: Eocene, 34 to 56 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.
Clay, sand. Age: Late Cretaceous, 66 to 72 million years old. About 3 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Sand. Age: Late Cretaceous, 66 to 72 million years old. About 2 mi of the line.

A raindrop that lands in Hopkins reaches the Atlantic Ocean by way of Cabin Branch, Myers Creek, Cedar Creek, the Congaree, the Santee and the South Santee: about 160 river miles.
Lake on the way: Lib Pines Lake.
70 miles of the trip are on the Santee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hopkins; river miles along the main stem, rounded.
Hopkins 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 Hopkins 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.
