The Loris plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
4.36 inches of rain fell in two days, the most for this week of the year since records began in 1931. The next wettest, 3.66 inches, fell in 2009.
Loris’s center stands about 100 ft above sea level. Within three miles the land runs from 80 ft to 150 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Bear Bluff Formation (sand, limestone), from the Tertiary, 2.6 to 66 million years old.
The section below crosses 5 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, limestone. Age: Tertiary, 2.6 to 66 million years old. About 9 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 6 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Clay. Age: Tertiary, 2.6 to 66 million years old. About 3 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Loris reaches the Atlantic Ocean by way of Gaskins Branch, Pleasant Meadow Swamp, Playcard Swamp, the Little Pee Dee, the Great Pee Dee, Schooner Creek and the Waccamaw: about 110 river miles.

Loris has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 37° in January. About 48 inches of rain fall in a normal year.
On November 14 Loris normally reaches 67° and falls to 46°. The record high is 82°, in 1931; the record low 23°, in 2013. The most rain on this date, 0.75 in, fell in 1952.
