Oak Grove’s center stands about 590 ft above sea level. Within three miles the land runs from 460 ft to 1,060 ft, a difference of 600 ft: hilly country. The highest named summit within 15 miles is Rebecca Mountain, about 1,540 ft, 9 miles east-southeast.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 8 mi of the line.
Phyllite, metaclastic. Age: Silurian to Devonian, 359 to 445 million years old. About 5 mi of the line.
Slate, metasiltstone. Age: Precambrian to Cambrian. About 4 mi of the line.
Marble, metasedimentary. Age: Cambrian to Ordovician, 445 to 542 million years old. About 1 mi of the line.
Quartzite, schist. Age: Precambrian to Paleozoic. About 1 mi of the line.
Greenstone, phyllite. Age: Paleozoic, 252 to 542 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 9 smaller units along the line are not listed.

A raindrop that lands in Oak Grove reaches Mobile Bay and the Gulf of America by way of McClungs Creek, Shirtee Creek, Tallaseehatchee Creek, the Coosa, the Alabama and the Mobile: about 460 river miles.
Lake on the way: Lay Lake.
310 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Oak Grove; river miles along the main stem, rounded.
Oak Grove has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 31° in January. About 57 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Oak Grove normally reaches 65° and falls to 39°. The record high is 87°, in 2024; the record low 17°, in 2019. The most rain on this date, 1.42 in, fell in 1957.
Normals 1991–2020 and records since 1950 at Sylacauga 4 NE, 6 miles east. NOAA, through RCC-ACIS.
