77° on Nov. 14, 1999, the hottest reading for this week of the year since 1894. Next is 75° in 1941.
Traer’s center stands about 970 ft above sea level. Within three miles the land runs from 880 ft to 1,040 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Cedar Valley Group (limestone, dolostone), from the Middle Devonian to Late Devonian, 374 to 388 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 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.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 15 mi of the line.
Shale, limestone, dolostone. Age: Late Devonian, 374 to 384 million years old. About 9 mi of the line.

A raindrop that lands in Traer reaches the Gulf of America by way of Coon Creek, Wolf Creek, the Cedar River, the Iowa and the Mississippi: about 1,610 river miles.

Traer has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 10° in January. A normal year brings about 33 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Traer normally reaches 47° and falls to 27°. The record high is 77°, in 1999; the record low 0°, in 1959. The most rain on this date, 1.43 in, fell in 1926.
