Perry’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 250 ft, a difference of 250 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Carlisle Mountain, about 570 ft, 7 miles west-northwest.
Under the town center the state geologic map shows Devonian Perry Formation, sandstone member, from the Devonian, 359 to 422 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 52×. 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. Age: Devonian, 359 to 422 million years old. About 7 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Age: Devonian, 359 to 422 million years old. About 2 mi of the line.

Perry has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 11° in January. A normal year brings about 95 inches of snow; with the rain, that comes to about 55 inches of water.
On November 14 Perry normally reaches 46° and falls to 31°. The record high is 65°, in 2005; the record low 15°, in 2019. The most rain on this date, 1.21 in, fell in 2006.
Normals 1991–2020 and records since 1994 at Robbinston, 8 miles north-northwest. NOAA, through RCC-ACIS.
