72° on Nov. 17, 1953, the hottest reading for this week of the year since 1916. Next is 69° in 1931.
Wilson’s center stands about 750 ft above sea level. Within three miles the land runs from 690 ft to 840 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Hickey Hill, about 1,040 ft, 12 miles south-southeast.
Under the town center the state geologic map shows Antrim Shale (black-shale), from the Late Devonian, 359 to 384 million years old.
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 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 16 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 8 mi of the line.

A raindrop that lands in Wilson reaches Lake Huron by way of Butterfield Creek, the Lower South Branch Thunder Bay and the Thunder Bay: about 20 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 Wilson; river miles along the main stem, rounded.
Wilson has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in February. A normal year brings about 78 inches of snow; with the rain, that comes to about 30 inches of water.
On November 14 Wilson normally reaches 45° and falls to 29°. The record high is 66°, in 1994; the record low 3°, in 1940. The most rain on this date, 0.61 in, fell in 1957.
Normals 1991–2020 and records since 1916 from the Alpena Area threaded record (Alpena County Regional Airport, 5 miles north-northeast). NOAA, through RCC-ACIS.
