82° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 80° in 1902.
Otway’s center stands about 590 ft above sea level. Within three miles the land runs from 580 ft to 1,110 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Peach Mountain, about 1,300 ft, 10 miles west-northwest.
Under the town center the state geologic map shows Ohio Shale (shale, black-shale), from the Devonian, 359 to 422 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. 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, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 21 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Shale, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 1 mi of the line.

A raindrop that lands in Otway reaches the Gulf of America by way of Bloody Run, Scioto Brush Creek, the Scioto, the Ohio and the Mississippi: about 1,620 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 Otway; river miles along the main stem, rounded.
Otway has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 43 inches of rain fall in a normal year.
On November 14 Otway normally reaches 57° and falls to 34°. The record high is 79°, in 1955; the record low 10°, in 1986. The most rain on this date, 1.36 in, fell in 2024.
Normals 1991–2020 and records since 1893 at Portsmouth-Sciotoville, 18 miles east-southeast. NOAA, through RCC-ACIS.
