84° on Nov. 11, 1989, the hottest reading for this week of the year since 1895. Next is 83° in 2016.
Climax’s center stands about 1,040 ft above sea level. Within three miles the land runs from 980 ft to 1,160 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Temple Knob, about 1,630 ft, 15 miles west.
Under the town center the state geologic map shows Shawnee Group (limestone, shale), from the Carboniferous, 299 to 324 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 41×. 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, shale. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.

A raindrop that lands in Climax reaches the Gulf of America by way of Otter Creek, the Fall, the Verdigris, the Arkansas and the Mississippi: about 1,270 river miles.
Lakes on the way: Oologah Lake, Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.

Climax has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 19° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Climax normally reaches 58° and falls to 32°. The record high is 82°, in 1999; the record low 6°, in 1959. The most rain on this date, 1.20 in, fell in 1909.
Normals 1991–2020 and records since 1895 at Eureka 1 E, 8 miles north-northwest. NOAA, through RCC-ACIS.
