86° on Nov. 11, 2020, the hottest reading for this week of the year since 1872. Next is 85° in 1896.
Hayneville’s center stands about 240 ft above sea level. Within three miles the land runs from 180 ft to 310 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Barganier Hill, about 600 ft, 14 miles south.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Holocene, less than 12,000 years old. About 8 mi of the line.
Chalk, marl. Age: Cretaceous, 66 to 145 million years old. About 6 mi of the line.
Chalk. Age: Cretaceous, 66 to 145 million years old. About 6 mi of the line.
Sand, clay, sandstone. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Hayneville reaches Mobile Bay and the Gulf of America by way of Big Swamp Creek, the Alabama and the Mobile: about 320 river miles.
240 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hayneville; river miles along the main stem, rounded.
Hayneville has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 36° in January. About 51 inches of rain fall in a normal year.
On November 14 Hayneville normally reaches 70° and falls to 43°. The record high is 85°, in 1993; the record low 26°, in 2013. The most rain on this date, 3.25 in, fell in 1921.
