15° on Nov. 15, 1963, the coldest reading for this week of the year since 1922. Next is 17° in 1969.
Gayle Mill’s center stands about 480 ft above sea level. Within three miles the land runs from 420 ft to 640 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Bulls Hill, about 750 ft, 9 miles north.
Under the town center the state geologic map shows Metagabbro - Chester, from the Neoproterozoic to Devonian, 359 to 1,000 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metagabbro. Age: Neoproterozoic to Devonian, 359 to 1,000 million years old. About 19 mi of the line.
Metagranite, metadiorite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Metagranite. Age: Neoproterozoic to Devonian, 359 to 1,000 million years old. About 1 mi of the line.

A raindrop that lands in Gayle Mill reaches the Atlantic Ocean by way of the Dry Fork, the Sandy, the Broad, the Congaree, the Santee and the South Santee: about 250 river miles.
Lake on the way: Lib Pines Lake.
70 miles of the trip are on the Santee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gayle Mill; river miles along the main stem, rounded.
Gayle Mill has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 30° in January. About 46 inches of rain fall in a normal year.
On November 14 Gayle Mill normally reaches 63° and falls to 38°. The record high is 82°, in 1989; the record low 20°, in 1963. The most rain on this date, 1.48 in, fell in 1940.
