79° on Nov. 15, 1993, the hottest reading for this week of the year since 1931. Next is 75° in 1973.
Dilworthtown’s center stands about 460 ft above sea level. Within three miles the land runs from 170 ft to 490 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Diamond Rock Hill, about 700 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Felsic and intermediate gneiss, from the Precambrian.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Dilworthtown reaches Delaware Bay and the Atlantic Ocean by way of Radley Run, Brandywine Creek, the Christina and the Delaware: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dilworthtown; river miles along the main stem, rounded.
Dilworthtown has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 24° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Dilworthtown normally reaches 53° and falls to 37°. The record high is 73°, in 1993; the record low 21°, in 1986. The most rain on this date, 2.17 in, fell in 1972.
Normals 1991–2020 and records since 1931 at Wilmington Porter Res, 9 miles south, 190 ft lower. NOAA, through RCC-ACIS.
