73° on Nov. 11, 2020, the hottest reading for this week of the year since 1880. Next is 71° in 1909.
Whitmore Lake’s center stands about 930 ft above sea level. Within three miles the land runs from 870 ft to 1,000 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Peach Mountain, about 1,110 ft, 10 miles west-southwest.
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 54×. 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 23 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.

A raindrop that lands in Whitmore Lake reaches Lake Erie by way of the Huron: 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 Whitmore Lake; river miles along the main stem, rounded.
Whitmore Lake has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 16° in January. A normal year brings about 61 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Whitmore Lake normally reaches 49° and falls to 31°. The record high is 71°, in 1909; the record low 11°, in 2018. The most rain on this date, 1.31 in, fell in 1957.
Normals 1991–2020 and records since 1880 at Ann Arbor U Of Mich, 11 miles south-southeast, 120 ft lower. NOAA, through RCC-ACIS.
