The Berlin plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
5° on Nov. 12, 2019, the coldest reading for this week of the year since 1996. Next is 8° in 2014.
Berlin’s center stands about 810 ft above sea level. Within three miles the land runs from 750 ft to 940 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Scott Hill, about 1,020 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Rhyolite (rhyolite, mixed-clastic), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 5 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.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 14 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 6 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Rhyolite, mixed-clastic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 0.4 mi of the line.

A raindrop that lands in Berlin reaches Lake Michigan by way of the Fox River: about 95 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 Berlin; river miles along the main stem, rounded.
Berlin 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 Berlin 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.
