Waterboro’s center stands about 570 ft above sea level. Within three miles the land runs from 300 ft to 880 ft, a difference of 580 ft: hilly country. The highest named summit within 15 miles is Clark Mountain, about 1,350 ft, 11 miles north-northwest.
Under the town center the state geologic map shows Devonian - Silurian Rindgemere Formation lower member (mudstone, limestone), from the Silurian to Devonian, 359 to 445 million years old.
The section below crosses 7 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.

A raindrop that lands in Waterboro reaches the Atlantic Ocean by way of the Little Ossipee and the Saco: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Waterboro; river miles along the main stem, rounded.
Waterboro has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 8° in January. A normal year brings about 81 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Waterboro normally reaches 46° and falls to 26°. The record high is 62°, in 2010; the record low 7°, in 2019. The most rain on this date, 1.13 in, fell in 2006.
Normals 1991–2020 and records since 1994 at Hollis, 4 miles northeast, 270 ft lower. NOAA, through RCC-ACIS.
