Wayne Heights’s center stands about 640 ft above sea level. Within three miles the land runs from 580 ft to 1,210 ft, a difference of 630 ft: hilly country. The highest named summit within 15 miles is Quirauk Mountain, about 2,150 ft, 4 miles southeast.
Under the town center the state geologic map shows Elbrook Formation (limestone), from the Cambrian, 487 to 542 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. 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 Wayne Heights reaches Chesapeake Bay and the Atlantic Ocean by way of East Branch Antietam Creek, Antietam Creek and the Potomac: about 230 river miles.
180 miles of the trip are on the Potomac.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wayne Heights; river miles along the main stem, rounded.
Wayne Heights has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 25° in January. About 36 inches of rain fall in a normal year.
On November 14 Wayne Heights normally reaches 55° and falls to 38°. The record high is 75°, in 1989; the record low 10°, in 1920. The most rain on this date, 1.91 in, fell in 1995.
