81° on Nov. 13, 2020, the hottest reading for this week of the year since 1990. Next is 80° in 2006.
Clarkesville’s center stands about 1,420 ft above sea level. Within three miles the land runs from 1,270 ft to 1,530 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Hickory Knob, about 3,400 ft, 15 miles northwest.
Under the town center the state geologic map shows Biotitic Gneiss / Mica Schist/ Amphibolite (amphibolite, biotite-gneiss, mica-schist), from the Precambrian to Paleozoic.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 9 mi of the line.
Metagraywacke, mica-schist. Age: Precambrian to Paleozoic. About 7 mi of the line.
Age: Precambrian to Paleozoic. About 6 mi of the line.
Quartzite, biotite-gneiss. Age: Precambrian to Paleozoic. About 0.9 mi of the line.
Schist. Age: Precambrian to Paleozoic. About 0.8 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Clarkesville reaches the Gulf of America by way of the Soquee, the Chattahoochee and the Apalachicola: about 510 river miles.
Lakes on the way: Walter F George Reservoir, Woodmen Youth Camp Lake, West Point Lake and Bartletts Ferry Lake.

Clarkesville has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 29° in January. About 62 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Clarkesville normally reaches 62° and falls to 36°. The record high is 78°, in 1999; the record low 18°, in 2013. The most rain on this date, 1.08 in, fell in 1998.
