28° on Nov. 11, 2025, the coldest reading for this week of the year since 1996. Next is 29° in 1997.
Evans’s center stands about 420 ft above sea level. Within three miles the land runs from 240 ft to 490 ft, a difference of 250 ft: rolling country.
Under the town center the state geologic map shows Granitic Gneiss undifferentiated, from the Precambrian to Paleozoic.
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 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Precambrian to Paleozoic. About 15 mi of the line.
Paragneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Clay, sand. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Granite. Age: Precambrian to Paleozoic. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Evans reaches the Atlantic Ocean by way of the Savannah: about 210 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Evans; river miles along the main stem, rounded.
Evans has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 40° in January. About 45 inches of rain fall in a normal year.
On November 14 Evans normally reaches 68° and falls to 48°. The record high is 81°, in 2007; the record low 32°, in 2013. The most rain on this date, 3.76 in, fell in 2008.
Normals 1991–2020 and records since 1996 at Augusta Daniel Field Airport, 7 miles southeast. NOAA, through RCC-ACIS.
