5° on Nov. 17, 1959, the coldest reading for this week of the year since 1898. Next is 11° in 1933.
Joyfield’s center stands about 840 ft above sea level. Within three miles the land runs from 630 ft to 1,090 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Buck Hills, about 1,150 ft, 5 miles east-southeast.
Under the town center the state geologic map shows Ellsworth 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 34×. 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 12 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.

A raindrop that lands in Joyfield reaches Lake Michigan by way of Herring Creek and the Herring Lake Outlet: about 5 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 Joyfield; river miles along the main stem, rounded.
Joyfield has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 19° in January. A normal year brings about 93 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Joyfield normally reaches 44° and falls to 33°. The record high is 62°, in 1964; the record low 12°, in 1933. The most rain on this date, 1.00 in, fell in 1916.
Normals 1991–2020 and records since 1898 at Frankfort 2 NE, 9 miles northwest, 110 ft higher. NOAA, through RCC-ACIS.
