South Wayne’s center stands about 850 ft above sea level. Within three miles the land runs from 770 ft to 980 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Benton Mound, about 1,260 ft, 15 miles southwest.
Under the town center the state geologic map shows Ancell Group (sandstone), from the Ordovician, 445 to 487 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 60×. 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. Age: Ordovician, 445 to 487 million years old. About 10 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 5 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 3 mi of the line.

A raindrop that lands in South Wayne reaches the Gulf of America by way of the Pecatonica, the Rock River and the Mississippi: about 1,720 river miles.
1,450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of South Wayne; river miles along the main stem, rounded.
South Wayne has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 11° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 40 inches of water.
Normals 1991–2020 and records since 1940 at Monroe Wwtp, 11 miles east-northeast, 140 ft higher. NOAA, through RCC-ACIS.
