Oakfield’s center stands about 900 ft above sea level. Within three miles the land runs from 830 ft to 1,080 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Mary Hill, about 1,090 ft, 11 miles northeast.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.

Dolostone. Age: Ordovician, 445 to 487 million years old. About 15 mi of the line.
Shale, dolostone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.

Oakfield straddles the St. Lawrence Divide. Rain on the southwest side runs to the Gulf of America; most of the rest goes to Lake Michigan.
From the center of town, a raindrop reaches Lake Michigan by way of the East Branch Fond Du Lac and 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. One that lands on the southwest side reaches the Gulf of America by way of the Rock River and the Mississippi: about 1,770 river miles.
Lake on the way: Lake Winnebago 6124.

Oakfield has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 11° in January. About 28 inches of rain fall in a normal year.
On November 14 Oakfield normally reaches 45° and falls to 29°. The record high is 64°, in 2025; the record low 10°, in 1996. The most rain on this date, 0.10 in, fell in 2024.
