82° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 80° in 1902.
Bourneville’s center stands about 700 ft above sea level. Within three miles the land runs from 660 ft to 1,150 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Nevins Hill, about 1,340 ft, 9 miles west.
Under the town center the state geologic map shows Peebles Dolomite, Lilley and Bisher Formations, Undivided (dolostone), from the Silurian, 425 to 434 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 26×. 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, black-shale. Age: Devonian, 359 to 422 million years old. About 14 mi of the line.
Dolostone. Age: Silurian, 425 to 434 million years old. About 5 mi of the line.
Shale, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 3 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 3 mi of the line.

A raindrop that lands in Bourneville reaches the Gulf of America by way of Lower Twin Creek, Paint Creek, the Scioto, the Ohio and the Mississippi: about 1,670 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bourneville; river miles along the main stem, rounded.
Bourneville has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Bourneville normally reaches 55° and falls to 32°. The record high is 80°, in 1909; the record low 8°, in 1986. The most rain on this date, 1.31 in, fell in 2024.
Normals 1991–2020 and records since 1893 at Waverly, 15 miles southeast, 130 ft lower. NOAA, through RCC-ACIS.
