12° on Nov. 14, 1986, the coldest reading for this week of the year since 1912. Next is 13° in 1957.
Wilkesville’s center stands about 720 ft above sea level. Within three miles the land runs from 640 ft to 910 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is The Pinnacle, about 1,090 ft, 13 miles north-northwest.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. 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, mudstone. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.

A raindrop that lands in Wilkesville reaches the Gulf of America by way of Flatlick Run, Raccoon Creek, the Ohio and the Mississippi: about 1,720 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wilkesville; river miles along the main stem, rounded.
Wilkesville has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 23° in January. About 44 inches of rain fall in a normal year.
On November 14 Wilkesville normally reaches 57° and falls to 34°. The record high is 79°, in 1993; the record low 12°, in 1986. The most rain on this date, 1.42 in, fell in 2024.
