75° on Nov. 11, 2022, the hottest reading for this week of the year since 1893. Next is 71° in 1971.
Chenequa’s center stands about 950 ft above sea level. Within three miles the land runs from 860 ft to 1,050 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Holy Hill, about 1,350 ft, 10 miles north-northeast.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 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 55×. 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, dolostone. Age: Ordovician, 445 to 487 million years old. About 9 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 8 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 7 mi of the line.

A raindrop that lands in Chenequa reaches the Gulf of America by way of the Oconomowoc, the Rock River and the Mississippi: about 1,730 river miles.
Lake on the way: Lake Koshkonong.
1,450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chenequa; river miles along the main stem, rounded.
Chenequa has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 11° in January. A normal year brings about 40 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Chenequa normally reaches 47° and falls to 29°. The record high is 69°, in 1999; the record low 9°, in 1995. The most rain on this date, 1.00 in, fell in 1957.
Normals 1991–2020 and records since 1893 at Oconomowoc Wwtp, 6 miles west. NOAA, through RCC-ACIS.
