74° on Nov. 15, 1953, the hottest reading for this week of the year since 1931. Next is 74° in 2001.
Wilmot’s center stands about 1,190 ft above sea level. Within three miles the land runs from 1,140 ft to 1,280 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Carlile Shale, from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. 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, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 6 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 5 mi of the line.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.

A raindrop that lands in Wilmot reaches the Gulf of America by way of the North Fork Whetstone, the Whetstone, the Minnesota and the Mississippi: about 2,190 river miles.
Lakes on the way: Big Stone Lake and Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wilmot; river miles along the main stem, rounded.
Wilmot has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 4° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 23 inches of water.
On November 14 Wilmot normally reaches 42° and falls to 23°. The record high is 69°, in 1990; the record low −7°, in 2014. The most rain on this date, 0.86 in, fell in 1947.
Normals 1991–2020 and records since 1931 from the Sisseton Area threaded record (Sisseton Municipal Airport, 19 miles north-northwest). NOAA, through RCC-ACIS.
