Meadville’s center stands about 1,240 ft above sea level. Within three miles the land runs from 1,070 ft to 1,580 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Round Knob, about 1,640 ft, 9 miles southeast.
Under the town center the state geologic map shows Berea Sandstone through Riceville Formation, undivided (shale), from the Late Devonian, 359 to 384 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 34×. 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: Late Devonian, 359 to 384 million years old. About 5 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.

A raindrop that lands in Meadville reaches the Gulf of America by way of French Creek, the Allegheny, the Ohio and the Mississippi: about 2,100 river miles.
970 miles of the trip are on the Ohio.

Meadville has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 17° in January. A normal year brings about 111 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Meadville normally reaches 48° and falls to 33°. The record high is 67°, in 2010; the record low 17°, in 1996. The most rain on this date, 0.53 in, fell in 2021.
Normals 1991–2020 and records since 1996 at Springboro 3 WNW, 18 miles northwest, 240 ft lower. NOAA, through RCC-ACIS.
