Welch’s center stands about 1,340 ft above sea level. Within three miles the land runs from 1,320 ft to 2,250 ft, a difference of 930 ft: steep hill country. The highest named summit within 15 miles is Johns Knob, about 2,990 ft, 12 miles east-southeast.
Under the town center the state geologic map shows New River Formation (sandstone), 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 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Welch reaches the Gulf of America by way of the Tug Fork, the Ohio and the Mississippi: about 1,790 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 Welch; river miles along the main stem, rounded.
Welch has a humid subtropical climate. Summer afternoons average 85° in July; winter nights fall to about 22° in January. About 49 inches of rain fall in a normal year.
On November 14 Welch normally reaches 57° and falls to 31°. The record high is 81°, in 1993; the record low 13°, in 2019. The most rain on this date, 0.75 in, fell in 2008.
Normals 1991–2020 and records since 1940 at Mullens 3 E, 17 miles northeast, 220 ft higher. NOAA, through RCC-ACIS.
