19° on Nov. 15, 1969, the coldest reading for this week of the year since 1900. Next is 20° in 1940.
McKenzie’s center stands about 460 ft above sea level. Within three miles the land runs from 250 ft to 460 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Claiborne Group; Gosport Sand and Lisbon Formation undifferentiated in part, from the Eocene, 34 to 56 million years old.
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 11 mi of the line.
Sand. Age: Eocene, 34 to 56 million years old. About 9 mi of the line.
Clay, limestone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Claystone. Age: Eocene, 34 to 56 million years old. About 0.7 mi of the line.
Clay, sand. Age: Paleocene, 56 to 66 million years old. About 0.4 mi of the line.

A raindrop that lands in McKenzie reaches Pensacola Bay and the Gulf of America by way of Piney Woods Creek, the Sepulga, the Conecuh, the Escambia and the Dead: about 140 river miles.
50 miles of the trip are on the Escambia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of McKenzie; river miles along the main stem, rounded.
McKenzie has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 34° in January. About 60 inches of rain fall in a normal year.
On November 14 McKenzie normally reaches 70° and falls to 41°. The record high is 84°, in 1993; the record low 22°, in 2013. The most rain on this date, 2.16 in, fell in 1972.
Normals 1991–2020 and records since 1900 at Greenville, 18 miles north-northeast, 120 ft lower. NOAA, through RCC-ACIS.
