Southbridge Town’s center stands about 670 ft above sea level. Within three miles the land runs from 410 ft to 900 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Burley Hill, about 1,320 ft, 9 miles west-southwest.
Under the town center the state geologic map shows Paxton Formation (granofels, schist), from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granofels, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 9 mi of the line.
Mica-schist. Age: Late Ordovician, 449 to 453 million years old. About 6 mi of the line.
Schist, phyllite. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Alkali-granite. Age: Neoproterozoic, 596 to 606 million years old. About 2 mi of the line.
Granite, tonalite. Age: Silurian, 428 to 445 million years old. About 2 mi of the line.
Quartzite, pelitic-schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in Southbridge Town reaches Long Island Sound and the Atlantic Ocean by way of Cohasse Brook, the Quinebaug, the Shetucket and the Thames: about 75 river miles.
55 miles of the trip are on the Quinebaug.

Southbridge Town has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 64 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Southbridge Town normally reaches 51° and falls to 32°. The record high is 69°, in 2010; the record low 12°, in 1986. The most rain on this date, 0.97 in, fell in 2018.
