West Bridgewater’s center stands about 70 ft above sea level. Within three miles the land runs from 50 ft to 160 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Great Blue Hill, about 630 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Rhode Island Formation (sandstone, graywacke), from the Carboniferous, 299 to 324 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, graywacke. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.
Granite. Age: Neoproterozoic, 615 to 645 million years old. About 6 mi of the line.
Granite, gneiss, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 1 mi of the line.
Metavolcanic. Age: Neoproterozoic, 542 to 1,000 million years old. About 0.4 mi of the line.

A raindrop that lands in West Bridgewater reaches Narragansett Bay and the Atlantic Ocean by way of West Meadow Brook, the Town and the Taunton: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of West Bridgewater; river miles along the main stem, rounded.
West Bridgewater has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 21° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 West Bridgewater normally reaches 54° and falls to 35°. The record high is 74°, in 1993; the record low 14°, in 1905. The most rain on this date, 2.07 in, fell in 1972.
