Dudley’s center stands about 350 ft above sea level. Within three miles the land runs from 320 ft to 360 ft, a difference of 40 ft: nearly flat ground. The highest named summit within 15 miles is Rock Knob, about 580 ft, 11 miles north-northeast.
Under the town center the state geologic map shows Holocene series (clay, silt, sand), from the Holocene, less than 12,000 years old.
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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 16 mi of the line.
Sand, clay, gravel. Age: Paleocene to Pliocene, 2.6 to 66 million years old. About 8 mi of the line.

A raindrop that lands in Dudley reaches the Gulf of America by way of the Saint Francis and the Mississippi: about 960 river miles.
690 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dudley; river miles along the main stem, rounded.
Dudley has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 28° in January. About 51 inches of rain fall in a normal year.
On November 14 Dudley normally reaches 58° and falls to 37°. The record high is 79°, in 1999; the record low 12°, in 1940. The most rain on this date, 2.12 in, fell in 1957.
