79° on Nov. 15, 2005, the hottest reading for this week of the year since 1994. Next is 79° in 2011.
East Newnan’s center stands about 950 ft above sea level. Within three miles the land runs from 820 ft to 1,010 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Sillimanite Schist, from the Precambrian to Paleozoic.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 61×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Schist. Age: Precambrian to Paleozoic. About 7 mi of the line.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 5 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 0.9 mi of the line.
Calc-silicate-gneiss. Age: Precambrian to Paleozoic. About 0.9 mi of the line.
Biotite-gneiss. Age: Precambrian to Paleozoic. About 0.3 mi of the line.

A raindrop that lands in East Newnan reaches the Gulf of America by way of Turkey Creek, White Oak Creek, the Flint and the Apalachicola: about 420 river miles.
290 miles of the trip are on the Flint.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of East Newnan; river miles along the main stem, rounded.
East Newnan has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 34° in January. About 49 inches of rain fall in a normal year.
On November 14 East Newnan normally reaches 66° and falls to 41°. The record high is 79°, in 2011; the record low 22°, in 2013. The most rain on this date, 0.79 in, fell in 2024.
