81° on Nov. 12, 1989, the hottest reading for this week of the year since 1911. Next is 80° in 1911.
Washburn’s center stands about 1,480 ft above sea level. Within three miles the land runs from 1,320 ft to 1,580 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Whitney Mountain, about 1,820 ft, 13 miles south-southeast.
Under the town center the state geologic map shows Chesterian Series (limestone, shale, sandstone), from the Carboniferous, 324 to 359 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 28×. 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. Age: Carboniferous, 324 to 359 million years old. About 19 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Limestone, shale, sandstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 0.3 mi of the line.

A raindrop that lands in Washburn reaches the Gulf of America by way of Flat Creek, the White River and the Mississippi: about 1,240 river miles.
Lake on the way: Table Rock Lake.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Washburn; river miles along the main stem, rounded.
Washburn has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 47 inches of rain fall in a normal year.
On November 14 Washburn normally reaches 58° and falls to 36°. The record high is 76°, in 2025; the record low 9°, in 1986. The most rain on this date, 0.86 in, fell in 1978.
Normals 1991–2020 and records since 1911 at Cassville 1 NE, 9 miles northeast, 160 ft lower. NOAA, through RCC-ACIS.
