Exeter’s center stands about 280 ft above sea level. Within three miles the land runs from 210 ft to 540 ft, a difference of 330 ft: rolling country. The highest named summit within 15 miles is Preble Hill, about 1,060 ft, 8 miles northwest.
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.

Schist, slate. Age: Silurian, 428 to 445 million years old. About 8 mi of the line.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 million years old. About 4 mi of the line.
Shale, sandstone. Age: Silurian, 428 to 434 million years old. About 1 mi of the line.
Marble, calc-silicate-rock, metasedimentary. Age: Silurian, 428 to 445 million years old. About 1 mi of the line.
Sandstone, shale. Age: Silurian, 422 to 445 million years old. About 0.4 mi of the line.

A raindrop that lands in Exeter reaches the Atlantic Ocean by way of the French Stream, the Kenduskeag Stream and the Penobscot: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Exeter; river miles along the main stem, rounded.
Exeter has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 6° in January. A normal year brings about 72 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Exeter normally reaches 47° and falls to 28°. The record high is 67°, in 2022; the record low 5°, in 2019. The most rain on this date, 1.03 in, fell in 1949.
Normals 1991–2020 and records since 1947 at Corinna, 6 miles west-southwest. NOAA, through RCC-ACIS.
