77° on Nov. 11, 2020, the hottest reading for this week of the year since 1946. Next is 74° in 1956.
Clymer’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,170 ft to 1,670 ft, a difference of 500 ft: hilly country. The highest named summit within 15 miles is Kinter Hill, about 2,110 ft, 9 miles north-northeast.
Under the town center the state geologic map shows Pottsville Formation (sandstone, conglomerate), from the Carboniferous, 299 to 324 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 19×. 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: Carboniferous, 299 to 324 million years old. About 18 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 0.4 mi of the line.

A raindrop that lands in Clymer reaches the Gulf of America by way of Two Lick Creek, Blacklick Creek, the Conemaugh, the Kiskiminetas, the Allegheny, the Ohio and the Mississippi: about 2,050 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 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 Clymer 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, 7 miles southwest, 130 ft lower. NOAA, through RCC-ACIS.
