79° on Nov. 13, 1999, the hottest reading for this week of the year since 1893. Next is 73° in 1917.
Macksburg’s center stands about 1,260 ft above sea level. Within three miles the land runs from 1,110 ft to 1,250 ft, a difference of 140 ft: gently rolling country.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 51×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, mudstone. Age: Late Pennsylvanian, 299 to 307 million years old. About 8 mi of the line.
Limestone, shale. Age: Late Pennsylvanian, 299 to 307 million years old. About 8 mi of the line.
Limestone, shale. Age: Late Pennsylvanian, 299 to 307 million years old. About 6 mi of the line.
Limestone, shale. Age: Middle Pennsylvanian to Late Pennsylvanian, 299 to 315 million years old. About 2 mi of the line.

A raindrop that lands in Macksburg reaches the Gulf of America by way of Rocky Branch, Welty Creek, the Middle River, the Des Moines and the Mississippi: about 1,580 river miles.
Lake on the way: Roberts Creek.
1,330 miles of the trip are on the Mississippi.

Macksburg has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 11° in January. A normal year brings about 26 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Macksburg normally reaches 48° and falls to 28°. The record high is 77°, in 1999; the record low −2°, in 1940. The most rain on this date, 0.73 in, fell in 2024.
