79° on Nov. 15, 2005, the hottest reading for this week of the year since 1994. Next is 79° in 2011.
Senoia’s center stands about 880 ft above sea level. Within three miles the land runs from 750 ft to 960 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Mica Schist/ Gneiss/ Amphibolite (gneiss, mica-schist, amphibolite), 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 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.
Gneiss, mica-schist, amphibolite. Age: Precambrian to Paleozoic. About 8 mi of the line.
Mica-schist. Age: Precambrian to Paleozoic. About 7 mi of the line.
Granite. Age: Precambrian to Paleozoic. About 7 mi of the line.
Granite. Age: Precambrian to Paleozoic. About 1 mi of the line.
Schist. Age: Precambrian to Paleozoic. About 0.3 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 Senoia reaches the Gulf of America by way of Keg Creek, Line Creek, the Flint and the Apalachicola: about 410 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 Senoia; river miles along the main stem, rounded.
Senoia 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 Senoia 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.
Normals 1991–2020 and records since 1994 at Peachtree City Falcon Field, 3 miles north-northwest. NOAA, through RCC-ACIS.
