86° on Nov. 11, 1989, the hottest reading for this week of the year since 1920. Next is 85° in 1999.
Dewey’s center stands about 700 ft above sea level. Within three miles the land runs from 670 ft to 750 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is Blue Mound, about 1,000 ft, 6 miles east-northeast.
Under the town center the state geologic map shows Chanute Formation (sandstone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. 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, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Dewey reaches the Gulf of America by way of Deer Creek, Coon Creek, the Caney, the Verdigris, the Arkansas and the Mississippi: about 1,150 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dewey; river miles along the main stem, rounded.
Dewey has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 22° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Dewey normally reaches 61° and falls to 35°. The record high is 80°, in 1988; the record low 12°, in 2018. The most rain on this date, 2.24 in, fell in 1985.
Normals 1991–2020 and records since 1920 at Bartlesville Municipal Airport, 5 miles west-southwest. NOAA, through RCC-ACIS.
