Searsboro’s center stands about 830 ft above sea level. Within three miles the land runs from 780 ft to 940 ft, a difference of 160 ft: gently rolling country.
The section below crosses 5 rock units mapped at the surface.
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.

A raindrop that lands in Searsboro reaches the Gulf of America by way of English Creek, the North Skunk, the Skunk and the Mississippi: about 1,540 river miles.

Searsboro has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 10° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Searsboro normally reaches 47° and falls to 27°. The record high is 78°, in 1999; the record low −1°, in 1959. The most rain on this date, 1.21 in, fell in 1902.
