72° on Nov. 11, 2022, the hottest reading for this week of the year since 1893. Next is 69° in 1964.
Kewaskum’s center stands about 950 ft above sea level. Within three miles the land runs from 930 ft to 1,110 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Dundee Mountain, about 1,250 ft, 10 miles north-northeast.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. 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 24 mi of the line.

A raindrop that lands in Kewaskum reaches Lake Michigan by way of the Milwaukee and the Kinnickinnic: about 80 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 Kewaskum; river miles along the main stem, rounded.
Kewaskum has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 9° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Kewaskum normally reaches 44° and falls to 26°. The record high is 69°, in 1999; the record low 5°, in 1995. The most rain on this date, 0.87 in, fell in 1991.
