North Lewisburg’s center stands about 1,100 ft above sea level. Within three miles the land runs from 1,020 ft to 1,270 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Campbell Hill, about 1,550 ft, 13 miles northwest.
Under the town center the state geologic map shows Salina Group (dolostone), from the Silurian, 422 to 445 million years old.
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 42×. 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 North Lewisburg reaches the Gulf of America by way of Big Darby Creek, the Scioto, the Ohio and the Mississippi: about 1,760 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Lewisburg; river miles along the main stem, rounded.
North Lewisburg has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. About 44 inches of rain fall in a normal year.
On November 14 North Lewisburg normally reaches 52° and falls to 33°. The record high is 75°, in 1909; the record low 5°, in 2019. The most rain on this date, 1.30 in, fell in 1972.
