4° on Nov. 17, 1959, the coldest reading for this week of the year since 1893. Next is 6° in 2019.
Mishawaka’s center stands about 730 ft above sea level. Within three miles the land runs from 690 ft to 910 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Reeves Hill, about 900 ft, 12 miles west-southwest.
Under the town center the state geologic map shows Ellsworth Shale, from the Devonian to Carboniferous, 324 to 422 million years old.
The section below crosses 3 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: Devonian to Carboniferous, 324 to 422 million years old. About 22 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.

A raindrop that lands in Mishawaka reaches Lake Michigan by way of the Saint Joseph: about 60 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 Mishawaka; river miles along the main stem, rounded.
Mishawaka has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 17° in January. A normal year brings about 64 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Mishawaka normally reaches 48° and falls to 32°. The record high is 71°, in 1971; the record low 10°, in 1986. The most rain on this date, 1.50 in, fell in 1957.
