Wayne’s center stands about 800 ft above sea level. Within three miles the land runs from 620 ft to 1,140 ft, a difference of 520 ft: hilly country. The highest named summit within 15 miles is Ashland Mountain, about 1,770 ft, 14 miles north.
Under the town center the state geologic map shows Long Run Member of Catskill Formation (sandstone, siltstone, mudstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 13 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.
Shale. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Black-shale. Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units along the line are not listed.

A raindrop that lands in Wayne reaches Chesapeake Bay and the Atlantic Ocean by way of Lower Little Swatara Creek, Swatara Creek and the Susquehanna: about 130 river miles.
Lake on the way: Lake Aldred.
55 miles of the trip are on Swatara Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wayne; river miles along the main stem, rounded.
Wayne has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 19° in January. About 48 inches of rain fall in a normal year.
On November 14 Wayne normally reaches 53° and falls to 33°. The record high is 70°, in 2022; the record low 17°, in 1986. The most rain on this date, 1.50 in, fell in 1983.
Normals 1991–2020 and records since 1978 at Blue Marsh Lake, 17 miles southeast, 450 ft lower. NOAA, through RCC-ACIS.
