Montville’s center stands about 460 ft above sea level. Within three miles the land runs from 260 ft to 980 ft, a difference of 720 ft: hilly country. The highest named summit within 15 miles is Spears Mountain, about 1,150 ft, 5 miles northeast.
Under the town center the state geologic map shows Ordovician - Precambrian Z Cape Elizabeth Formation (slate), from the Neoproterozoic to Ordovician, 445 to 1,000 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Slate. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 20 mi of the line.
Sandstone, limestone. Age: Ordovician to Devonian, 359 to 487 million years old. About 3 mi of the line.
Quartzite. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 1 mi of the line.

A raindrop that lands in Montville reaches the Atlantic Ocean by way of the Saint George: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Montville; river miles along the main stem, rounded.
Montville has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 12° in January. A normal year brings about 69 inches of snow; with the rain, that comes to about 56 inches of water.
On November 14 Montville normally reaches 47° and falls to 32°. The record high is 65°, in 2010; the record low 8°, in 1986. The most rain on this date, 1.47 in, fell in 2018.
Normals 1991–2020 and records since 1976 at West Rockport 1 NNW, 18 miles south-southeast. NOAA, through RCC-ACIS.
