The Parma Heights plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
74° on Nov. 12, 1949, the hottest reading for this week of the year since 1871. Next is 73° in 1915.
Parma Heights’s center stands about 870 ft above sea level. Within three miles the land runs from 780 ft to 1,150 ft, a difference of 370 ft: rolling country.
Under the town center the state geologic map shows Maxville Limestone; Rushville, Logan, and Cuyhoga Formations, Undivided (shale, siltstone, sandstone), from the Devonian to Carboniferous, 324 to 422 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. 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, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 8 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Sandstone, shale. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.

A raindrop that lands in Parma Heights reaches Lake Erie by way of Big Creek and the Cuyahoga: about 17 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

Parma Heights has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 22° in January. A normal year brings about 64 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Parma Heights normally reaches 52° and falls to 37°. The record high is 72°, in 1994; the record low 13°, in 1986. The most rain on this date, 1.07 in, fell in 2011.
