78° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 74° in 1893.
Bucyrus’s center stands about 1,010 ft above sea level. Within three miles the land runs from 970 ft to 1,060 ft, a difference of 90 ft: gently rolling country.
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 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 56×. 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 9 mi of the line.
Sandstone, shale. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Limestone. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Limestone. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Shale. Age: Devonian, 359 to 422 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

Bucyrus straddles the St. Lawrence Divide. Rain on the south side runs to the Gulf of America; most of the rest goes to Lake Erie.
From the center of town, a raindrop reaches Lake Erie by way of the Sandusky: about 110 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic. One that lands on the south side reaches the Gulf of America by way of the Little Scioto, the Scioto, the Ohio and the Mississippi: about 1,800 river miles.

Bucyrus has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 20° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Bucyrus normally reaches 52° and falls to 35°. The record high is 72°, in 1909; the record low 6°, in 2019. The most rain on this date, 1.15 in, fell in 1972.
