75° on Nov. 11, 2020, the hottest reading for this week of the year since 1891. Next is 70° in 1928.
Hanover’s center stands about 1,120 ft above sea level. Within three miles the land runs from 1,020 ft to 1,200 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Marshall Sandstone, from the Carboniferous, 324 to 359 million years old.
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.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Hanover reaches Lake Michigan by way of the South Branch Kalamazoo and the Kalamazoo: about 160 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
130 miles of the trip are on the Kalamazoo.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hanover; river miles along the main stem, rounded.
Hanover has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 15° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Hanover normally reaches 48° and falls to 30°. The record high is 69°, in 1989; the record low 8°, in 2019. The most rain on this date, 1.33 in, fell in 1957.
Normals 1991–2020 and records since 1891 at Hillsdale, 12 miles south-southwest. NOAA, through RCC-ACIS.
