17° on Nov. 15, 1969, the coldest reading for this week of the year since 1930. Next is 17° in 2019.
Mantachie’s center stands about 350 ft above sea level. Within three miles the land runs from 270 ft to 430 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Eutaw formation (sand, clay), from the Late Cretaceous, 66 to 100 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, clay. Age: Late Cretaceous, 66 to 100 million years old. About 12 mi of the line.
Sand, clay. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Sand. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Chalk, clay. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Chalk. Age: Late Cretaceous, 66 to 100 million years old. About 0.2 mi of the line.

A raindrop that lands in Mantachie reaches Mobile Bay and the Gulf of America by way of Mantachie Creek, the Tombigbee and the Mobile: about 450 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mantachie; river miles along the main stem, rounded.
Mantachie has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 34° in January. About 58 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Mantachie normally reaches 65° and falls to 42°. The record high is 85°, in 1955; the record low 21°, in 2014. The most rain on this date, 2.55 in, fell in 1930.
Normals 1991–2020 and records since 1930 from the Tupelo Area threaded record (Tupelo, 14 miles west-southwest). NOAA, through RCC-ACIS.
