13° on Nov. 15, 1969, the coldest reading for this week of the year since 1955. Next is 17° in 1963.
Cleveland’s center stands about 860 ft above sea level. Within three miles the land runs from 740 ft to 1,060 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Little Mountain, about 1,650 ft, 14 miles east-southeast.
Under the town center the state geologic map shows Nolichucky Shale, and Maryville, Rogersville, and Rutledge Formations, and Pumpkin Valley Shale, from the Cambrian, 487 to 542 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Cleveland reaches the Gulf of America by way of South Mouse Creek, the Hiwassee, the Tennessee, the Ohio and the Mississippi: about 1,550 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cleveland; river miles along the main stem, rounded.
Cleveland has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 29° in January. About 58 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Cleveland normally reaches 62° and falls to 37°. The record high is 79°, in 1999; the record low 19°, in 2013. The most rain on this date, 1.22 in, fell in 2007.
Normals 1991–2020 and records since 1955 at Cleveland Filter Plant, 6 miles northeast. NOAA, through RCC-ACIS.
