New Miami’s center stands about 600 ft above sea level. Within three miles the land runs from 570 ft to 860 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Mount Auburn, about 960 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Kope Formation (shale), from the Middle Ordovician to Late Ordovician, 445 to 471 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 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 9 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 459 million years old. About 6 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 5 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 3 mi of the line.
Dolostone, limestone, shale. Age: Silurian, 422 to 445 million years old. About 0.8 mi of the line.

A raindrop that lands in New Miami reaches the Gulf of America by way of Four Mile Creek, the Great Miami, the Ohio and the Mississippi: about 1,490 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 New Miami; river miles along the main stem, rounded.
New Miami has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 21° in January. About 45 inches of rain fall in a normal year.
On November 14 New Miami normally reaches 54° and falls to 33°. The record high is 78°, in 1931; the record low 10°, in 2019. The most rain on this date, 1.45 in, fell in 2011.
Normals 1991–2020 and records since 1911 at Fairfield, 6 miles south-southwest. NOAA, through RCC-ACIS.
