14° on Nov. 13, 2019, the coldest reading for this week of the year since 1961. Next is 17° in 2014.
Diablock’s center stands about 930 ft above sea level. Within three miles the land runs from 870 ft to 1,830 ft, a difference of 960 ft: steep hill country. The highest named summit within 15 miles is Dixon Knob, about 2,140 ft, 8 miles southeast.
Under the town center the state geologic map shows Breathitt Formation, lower part (shale, siltstone), from the Carboniferous, 299 to 324 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 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 18 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone, siltstone. Age: Carboniferous, 299 to 324 million years old. About 0.5 mi of the line.

A raindrop that lands in Diablock reaches the Gulf of America by way of the North Fork Kentucky, the Kentucky, the Ohio and the Mississippi: about 1,760 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 Diablock; river miles along the main stem, rounded.
Diablock has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 24° in January. About 52 inches of rain fall in a normal year.
On November 14 Diablock normally reaches 59° and falls to 34°. The record high is 84°, in 1994; the record low 14°, in 2019. The most rain on this date, 0.59 in, fell in 2024.
Normals 1991–2020 and records since 1961 at Buckhorn Lake, 18 miles west-northwest, 150 ft lower. NOAA, through RCC-ACIS.
