Brush Valley’s center stands about 1,400 ft above sea level. Within three miles the land runs from 1,320 ft to 1,890 ft, a difference of 570 ft: hilly country. The highest named summit within 15 miles is Rager Mountain, about 2,620 ft, 11 miles southeast.
Under the town center the state geologic map shows Glenshaw Formation (shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 rock units mapped at the surface.

A raindrop that lands in Brush Valley reaches the Gulf of America by way of Little Brush Creek, Brush Creek, Blacklick Creek, the Conemaugh, the Kiskiminetas, the Allegheny, the Ohio and the Mississippi: about 2,040 river miles.
970 miles of the trip are on the Ohio.

Brush Valley has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 18° in January. A normal year brings about 46 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Brush Valley normally reaches 52° and falls to 30°. The record high is 73°, in 1994; the record low 11°, in 1986. The most rain on this date, 0.77 in, fell in 1997.
Normals 1991–2020 and records since 1946 at Indiana 3 SE, 5 miles northwest, 300 ft lower. NOAA, through RCC-ACIS.
