Watterstown’s center stands about 850 ft above sea level. Within three miles the land runs from 640 ft to 1,150 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Red Hill, about 1,190 ft, 13 miles north.
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 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Watterstown has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 7° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Watterstown normally reaches 46° and falls to 27°. The record high is 75°, in 1999; the record low 6°, in 1996. The most rain on this date, 0.57 in, fell in 1994.
