The Ocilla plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
21° on Nov. 16, 1940, the coldest reading for this week of the year since 1911. Next is 22° in 1969.
Ocilla’s center stands about 360 ft above sea level. Within three miles the land runs from 300 ft to 390 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Neogene undifferentiated (sandstone, claystone), from the Tertiary Neogene, 2.6 to 23 million years old.
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.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 24 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 Ocilla reaches the Gulf of America by way of Stump Creek, Little Brushy Creek, Reedy Creek, the Willacoochee, the Alapaha and the Suwannee: about 270 river miles.
130 miles of the trip are on the Suwannee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ocilla; river miles along the main stem, rounded.
Ocilla has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 37° in January. About 48 inches of rain fall in a normal year.
On November 14 Ocilla normally reaches 68° and falls to 45°. The record high is 84°, in 1931; the record low 22°, in 2019. The most rain on this date, 1.65 in, fell in 1940.
