77° on Nov. 11, 2020, the hottest reading for this week of the year since 1895. Next is 73° in 1990.
Clymer’s center stands about 1,460 ft above sea level. Within three miles the land runs from 1,420 ft to 1,850 ft, a difference of 430 ft: hilly country. The highest named summit within 15 miles is Jackson Hill, about 1,980 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Conneaut Group, undivided (shale, sandstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 30×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 8 mi of the line.
Shale, sandstone. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Sandstone, shale. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
Sandstone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Clymer reaches the Gulf of America by way of Brownell Branch, Brokenstraw Creek, the Allegheny, the Ohio and the Mississippi: about 2,170 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clymer; river miles along the main stem, rounded.
Clymer has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 98 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Clymer normally reaches 49° and falls to 31°. The record high is 71°, in 2010; the record low 7°, in 1905. The most rain on this date, 0.88 in, fell in 1988.
Normals 1991–2020 and records since 1895 from the Jamestown Area threaded record (Jamestown 4 ENE, 25 miles east-northeast, 210 ft lower). NOAA, through RCC-ACIS.
