33° on Nov. 14, 2018, the coldest reading for this week of the year since 1941. Next is 34° in 1970.
Perezville’s center stands about 140 ft above sea level. Within three miles the land runs from 110 ft to 200 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Lissie Formation (silt, sand, clay), from the Pleistocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt, sand, clay. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Clay, sandstone. Age: Miocene, 5.3 to 23 million years old. About 1 mi of the line.
Silt, clay. Age: Holocene, less than 12,000 years old. About 0.3 mi of the line.

Perezville has a hot semi-arid climate. Summer afternoons average 100° in August; winter nights fall to about 53° in January. About 22 inches of rain fall in a normal year.
On November 14 Perezville normally reaches 80° and falls to 60°. The record high is 93°, in 1989; the record low 33°, in 2018. The most rain on this date, 0.20 in, fell in 1959.
