17° on Nov. 15, 1969, the coldest reading for this week of the year since 1947. Next is 19° in 1974.
Oakdale’s center stands about 900 ft above sea level. Within three miles the land runs from 770 ft to 1,690 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Buffalo Mountain, about 3,370 ft, 15 miles northeast.
Under the town center the state geologic map shows Rockcastle Conglomerate (sandstone, conglomerate), from the Carboniferous, 299 to 324 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Shale. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.

A raindrop that lands in Oakdale reaches the Gulf of America by way of Laurel Branch, the Emory, the Tennessee, the Ohio and the Mississippi: about 1,600 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 Oakdale; river miles along the main stem, rounded.
Oakdale has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 30° in January. About 56 inches of rain fall in a normal year.
On November 14 Oakdale normally reaches 61° and falls to 38°. The record high is 78°, in 1999; the record low 20°, in 1986. The most rain on this date, 1.40 in, fell in 2024.
Normals 1991–2020 and records since 1947 from the Oak Ridge Area threaded record (Oak Ridge Asos, 18 miles east). NOAA, through RCC-ACIS.
