71° on Nov. 17, 1941, the hottest reading for this week of the year since 1893. Next is 71° in 2012.
Clermont’s center stands about 860 ft above sea level. Within three miles the land runs from 800 ft to 1,170 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Corn Hill, about 1,210 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Galena Group and Platteville Formation (dolostone, limestone), from the Late Ordovician, 447 to 459 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. 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, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 15 mi of the line.
Dolostone. Age: Late Ordovician to Silurian, 434 to 447 million years old. About 5 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 4 mi of the line.

A raindrop that lands in Clermont reaches the Gulf of America by way of Dry Run, the Turkey and the Mississippi: about 1,650 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clermont; river miles along the main stem, rounded.
Clermont has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 7° in January. A normal year brings about 40 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Clermont normally reaches 45° and falls to 26°. The record high is 69°, in 1990; the record low −5°, in 1916. The most rain on this date, 1.17 in, fell in 1902.
Normals 1991–2020 and records since 1893 at Postville, 8 miles northeast, 300 ft higher. NOAA, through RCC-ACIS.
