74° on Nov. 16, 1993, the hottest reading for this week of the year since 1888. Next is 73° in 2020.
South Coventry’s center stands about 540 ft above sea level. Within three miles the land runs from 270 ft to 740 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Snow Hill, about 1,230 ft, 14 miles north-northeast.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Schist, calc-silicate-rock. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Gabbro. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Schist. Age: Silurian to Devonian, 359 to 445 million years old. About 1 mi of the line.
Gneiss. Age: Middle Ordovician, 459 to 471 million years old. About 1 mi of the line.
Gneiss, amphibolite. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 1 mi of the line.

A raindrop that lands in South Coventry reaches Long Island Sound and the Atlantic Ocean by way of Mill Brook, the Willimantic, the Shetucket and the Thames: about 45 river miles.

South Coventry has a hot-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 19° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 South Coventry normally reaches 51° and falls to 34°. The record high is 67°, in 1902; the record low 10°, in 1905. The most rain on this date, 2.21 in, fell in 1937.
