West Union’s center stands about 2,310 ft above sea level. Within three miles the land runs from 1,850 ft to 2,360 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Bailey Hill, about 2,590 ft, 11 miles south.
Under the town center the state geologic map shows Conneaut Group, undivided (shale, sandstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 19×. 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, sandstone. Age: Late Devonian, 359 to 384 million years old. About 16 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 1 mi of the line.
Shale, siltstone, sandstone. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.

West Union straddles the St. Lawrence Divide. Rain on the west side runs to Lake Ontario; most of the rest goes to Chesapeake Bay and the Atlantic Ocean.
From the center of town, a raindrop reaches Chesapeake Bay and the Atlantic Ocean by way of Bennetts Creek, the Tioga, the Chemung and the Susquehanna: about 390 river miles. One that lands on the west side reaches Lake Ontario by way of Wileyville Creek, Cryder Creek and the Genesee: about 160 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Lake Aldred.
250 miles of the trip are on the Susquehanna.

West Union has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 12° in January. A normal year brings about 82 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 West Union normally reaches 47° and falls to 27°. The record high is 67°, in 1994; the record low 7°, in 1939. The most rain on this date, 1.91 in, fell in 1995.
Normals 1991–2020 and records since 1893 at Alfred, 17 miles north-northwest, 390 ft lower. NOAA, through RCC-ACIS.
