Octavia’s center stands about 1,410 ft above sea level. Within three miles the land runs from 1,370 ft to 1,630 ft, a difference of 260 ft: rolling country.
Under the town center the state geologic map shows Greenhorn Limestone and Graneros Shale (shale, limestone), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. 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, shale. Age: Early Cretaceous, 100 to 145 million years old. About 13 mi of the line.
Shale, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 10 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.

A raindrop that lands in Octavia reaches the Gulf of America by way of the Platte, the Missouri and the Mississippi: about 1,850 river miles.
1,170 miles of the trip are on the Mississippi.

Octavia has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 14° in January. A normal year brings about 26 inches of snow; with the rain, that comes to about 29 inches of water.
On November 14 Octavia normally reaches 48° and falls to 28°. The record high is 78°, in 2025; the record low −7°, in 1940. The most rain on this date, 1.16 in, fell in 1926.
