East Brandywine’s center stands about 560 ft above sea level. Within three miles the land runs from 250 ft to 670 ft, a difference of 420 ft: hilly country. The highest named summit within 15 miles is Welsh Mountain, about 1,080 ft, 12 miles west-northwest.
Under the town center the state geologic map shows Felsic and intermediate gneiss (muscovite-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 22×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Muscovite-gneiss. Age: Precambrian. About 6 mi of the line.
Age: Precambrian. About 4 mi of the line.
Mica-schist. Age: Paleozoic, 252 to 542 million years old. About 3 mi of the line.
Schist, phyllite. Age: Paleozoic, 252 to 542 million years old. About 2 mi of the line.
Gneiss. Age: Precambrian. About 2 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. 7 smaller units along the line are not listed.

A raindrop that lands in East Brandywine reaches Delaware Bay and the Atlantic Ocean by way of Beaver Creek, East Branch Brandywine Creek, Brandywine Creek, the Christina and the Delaware: about 75 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of East Brandywine; river miles along the main stem, rounded.
East Brandywine has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 24° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 East Brandywine normally reaches 54° and falls to 37°. The record high is 70°, in 1993; the record low 25°, in 2004. The most rain on this date, 0.50 in, fell in 2008.
Normals 1991–2020 and records since 1992 at New Holland 2 SE, 17 miles west. NOAA, through RCC-ACIS.
