5° on Nov. 12, 2019, the coldest reading for this week of the year since 1996. Next is 8° in 2014.
Utica’s center stands about 870 ft above sea level. Within three miles the land runs from 810 ft to 920 ft, a difference of 110 ft: gently rolling country.
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 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 18 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.

A raindrop that lands in Utica reaches Lake Michigan by way of Waukau Creek and the Fox River: about 90 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124 and Lake Butte des Morts.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Utica; river miles along the main stem, rounded.
Utica has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. About 31 inches of rain fall in a normal year.
On November 14 Utica normally reaches 45° and falls to 29°. The record high is 62°, in 2025; the record low 10°, in 1996. The most rain on this date, 0.21 in, fell in 2024.
