Fort Winnebago’s center stands about 860 ft above sea level. Within three miles the land runs from 770 ft to 960 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Cascade Mountain, about 1,310 ft, 9 miles south-southwest.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 45×. 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 23 mi of the line.
Quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 1 mi of the line.

A raindrop that lands in Fort Winnebago reaches Lake Michigan by way of the Fox River: about 160 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, Lake Butte des Morts and Puckaway Lake.
50 miles of the trip are on the Fox River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fort Winnebago; river miles along the main stem, rounded.
Fort Winnebago has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Fort Winnebago normally reaches 45° and falls to 29°. The record high is 72°, in 1999; the record low 1°, in 1916. The most rain on this date, 0.63 in, fell in 1902.
