77° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 75° in 1927.
Delphos’s center stands about 770 ft above sea level. Within three miles the land runs from 750 ft to 790 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Salina Group (dolostone), from the Silurian, 422 to 445 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Silurian, 422 to 445 million years old. About 15 mi of the line.
Dolostone. Age: Silurian, 428 to 445 million years old. About 9 mi of the line.

A raindrop that lands in Delphos reaches Lake Erie by way of the Flat Fork, Jennings Creek, the Auglaize and the Maumee: about 110 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
65 miles of the trip are on the Maumee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Delphos; river miles along the main stem, rounded.
Delphos has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 18° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Delphos normally reaches 50° and falls to 33°. The record high is 72°, in 1956; the record low 5°, in 2019. The most rain on this date, 1.09 in, fell in 1897.
Normals 1991–2020 and records since 1893 at Van Wert 1 S, 13 miles west. NOAA, through RCC-ACIS.
