Trumbauersville’s center stands about 530 ft above sea level. Within three miles the land runs from 430 ft to 710 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Gap Hill, about 1,160 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Brunswick Formation (mudstone), from the Triassic, 202 to 252 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 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone. Age: Triassic, 202 to 252 million years old. About 13 mi of the line.
Basalt. Age: Jurassic, 145 to 202 million years old. About 7 mi of the line.
Conglomerate. Age: Triassic, 202 to 252 million years old. About 2 mi of the line.
Gneiss. Age: Precambrian. About 1 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 0.6 mi of the line.
Argillite. Age: Triassic, 202 to 252 million years old. About 0.3 mi of the line.

A raindrop that lands in Trumbauersville reaches Delaware Bay and the Atlantic Ocean by way of Unami Creek, Perkiomen Creek, the Schuylkill and the Delaware: about 120 river miles.
60 miles of the trip are on the Delaware.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Trumbauersville; river miles along the main stem, rounded.
Trumbauersville has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Trumbauersville normally reaches 54° and falls to 32°. The record high is 66°, in 2010; the record low 18°, in 1996. The most rain on this date, 0.55 in, fell in 2008.
Normals 1991–2020 and records since 1948 at Sellersville, 5 miles southeast, 230 ft lower. NOAA, through RCC-ACIS.
