86° on Nov. 11, 2020, the hottest reading for this week of the year since 1892. Next is 85° in 1958.
Robins AFB’s center stands about 300 ft above sea level. Within three miles the land runs from 250 ft to 430 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Andrews Hill, about 600 ft, 11 miles north.
Under the town center the state geologic map shows Providence Sand, from the Cretaceous, 66 to 145 million years old.
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 56×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Cretaceous, 66 to 145 million years old. About 6 mi of the line.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 6 mi of the line.
Sand, clay. Age: Cretaceous to Tertiary, 2.6 to 145 million years old. About 3 mi of the line.
Clay. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Fine-detrital. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Clay, sand. Age: Cretaceous, 66 to 145 million years old. 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 Robins AFB reaches the Atlantic Ocean by way of the Ocmulgee and the Altamaha: about 290 river miles.
160 miles of the trip are on the Ocmulgee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Robins AFB; river miles along the main stem, rounded.
Robins AFB has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 36° in January. About 47 inches of rain fall in a normal year.
On November 14 Robins AFB normally reaches 70° and falls to 42°. The record high is 83°, in 1955; the record low 21°, in 2013. The most rain on this date, 1.40 in, fell in 1957.
