77° on Nov. 11, 2020, the hottest reading for this week of the year since 1895. Next is 73° in 1990.
Sugar Grove’s center stands about 1,400 ft above sea level. Within three miles the land runs from 1,350 ft to 1,900 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is Gardners Rocks, about 2,040 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Chadakoin Formation (siltstone, shale), 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 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.
Siltstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 7 mi of the line.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.

A raindrop that lands in Sugar Grove reaches the Gulf of America by way of Jackson Run, Conewango Creek, the Allegheny, the Ohio and the Mississippi: about 2,150 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sugar Grove; river miles along the main stem, rounded.
Sugar Grove has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 98 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Sugar Grove normally reaches 49° and falls to 31°. The record high is 71°, in 2010; the record low 7°, in 1905. The most rain on this date, 0.88 in, fell in 1988.
