12° on Nov. 16, 1996, the coldest reading for this week of the year since 1956. Next is 14° in 1956.
Plainfield Village’s center stands about 170 ft above sea level. Within three miles the land runs from 110 ft to 590 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Jerimoth Hill, about 860 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Quinebaug Formation (gneiss), from the Ordovician to Middle Ordovician, 459 to 487 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. 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 Plainfield Village reaches Long Island Sound and the Atlantic Ocean by way of Horse Brook, the Quinebaug, the Shetucket and the Thames: about 35 river miles.

Plainfield Village 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 28 inches of snow; with the rain, that comes to about 52 inches of water.
On November 14 Plainfield Village normally reaches 54° and falls to 35°. The record high is 72°, in 1993; the record low 17°, in 1986. The most rain on this date, 2.25 in, fell in 1972.
