0° on Nov. 17, 1959, the coldest reading for this week of the year since 1886. Next is 1° in 1933.
Sobieski’s center stands about 680 ft above sea level. Within three miles the land runs from 590 ft to 740 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 19 mi of the line.

A raindrop that lands in Sobieski reaches Lake Michigan by way of the Little Suamico: about 6 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 Sobieski; river miles along the main stem, rounded.
Sobieski has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. A normal year brings about 56 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Sobieski normally reaches 44° and falls to 30°. The record high is 65°, in 1958; the record low 3°, in 1916. The most rain on this date, 0.95 in, fell in 1956.
Normals 1991–2020 and records since 1886 from the Green Bay Area threaded record (Green Bay A S International Airport, 17 miles south-southwest). NOAA, through RCC-ACIS.
