80° on Nov. 15, 1993, the hottest reading for this week of the year since 1894. Next is 78° in 1973.
Greenville’s center stands about 280 ft above sea level. Within three miles the land runs from 80 ft to 430 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Harmony Hill, about 530 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Amphibolite, from the Paleozoic, 252 to 542 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 40×. 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, silt. Age: Early Cretaceous, 100 to 145 million years old. About 8 mi of the line.
Mica-schist. Age: Paleozoic, 252 to 542 million years old. About 4 mi of the line.
Schist, gneiss. Age: Paleozoic, 252 to 542 million years old. About 3 mi of the line.
Age: Paleozoic, 252 to 542 million years old. About 3 mi of the line.
Gneiss. Age: Precambrian. 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. 2 smaller units along the line are not listed.

A raindrop that lands in Greenville reaches Delaware Bay and the Atlantic Ocean by way of Little Mill Creek, the Christina and the Delaware: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greenville; river miles along the main stem, rounded.
Greenville has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 26° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Greenville normally reaches 56° and falls to 38°. The record high is 76°, in 1955; the record low 20°, in 1986. The most rain on this date, 2.42 in, fell in 1972.
Normals 1991–2020 and records since 1894 from the Wilmington Area threaded record (Wilmington Airport, 7 miles south, 210 ft lower). NOAA, through RCC-ACIS.
