87° on Nov. 15, 2025, the hottest reading for this week of the year since 1911. Next is 86° in 2016.
Cimarron’s center stands about 2,680 ft above sea level. Within three miles the land runs from 2,590 ft to 2,750 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Alluvium (sand, silt, clay), from the Pleistocene, less than 2.6 million years old.
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 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.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 11 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Sand, silt, clay. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Cimarron reaches the Gulf of America by way of the Arkansas and the Mississippi: about 1,550 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
660 miles of the trip are on the Arkansas.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cimarron; river miles along the main stem, rounded.
Cimarron has a hot-summer humid continental climate. Summer afternoons average 93° in July; winter nights fall to about 18° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Cimarron normally reaches 57° and falls to 30°. The record high is 78°, in 2007; the record low −2°, in 1959. The most rain on this date, 0.54 in, fell in 1926.
