Monroe’s center stands about 1,530 ft above sea level. Within three miles the land runs from 1,490 ft to 1,700 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Niobrara Formation (limestone, shale), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 16 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.

A raindrop that lands in Monroe reaches the Gulf of America by way of the Loup, the Platte, the Missouri and the Mississippi: about 1,880 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Monroe; river miles along the main stem, rounded.
Monroe has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 13° in January. A normal year brings about 29 inches of snow; with the rain, that comes to about 28 inches of water.
On November 14 Monroe normally reaches 50° and falls to 27°. The record high is 83°, in 2025; the record low −11°, in 1916. The most rain on this date, 0.98 in, fell in 1926.
