4° on Nov. 12, 2019, the coldest reading for this week of the year since 1897. Next is 5° in 1933.
Quincy’s center stands about 1,030 ft above sea level. Within three miles the land runs from 980 ft to 1,080 ft, a difference of 100 ft: gently rolling country.
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.
Shale. Age: Carboniferous, 324 to 359 million years old. About 20 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.

A raindrop that lands in Quincy reaches Lake Michigan by way of Bagley Creek, South Branch Hog Creek, Hog Creek, the Coldwater and the Saint Joseph: about 170 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Quincy; river miles along the main stem, rounded.
Quincy has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 16° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Quincy normally reaches 47° and falls to 31°. The record high is 69°, in 1902; the record low 8°, in 2019. The most rain on this date, 0.96 in, fell in 1957.
Normals 1991–2020 and records since 1897 at Coldwater St School, 6 miles west-northwest. NOAA, through RCC-ACIS.
