14° on Nov. 13, 2019, the coldest reading for this week of the year since 1987. Next is 21° in 1997.
Germantown’s center stands about 380 ft above sea level. Within three miles the land runs from 250 ft to 400 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Quaternary, less than 2.6 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 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.
Silt. Age: Quaternary, less than 2.6 million years old. About 20 mi of the line.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Germantown reaches the Gulf of America by way of the Wolf River and the Mississippi: about 780 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Germantown; river miles along the main stem, rounded.
Germantown has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 30° in January. About 57 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Germantown normally reaches 63° and falls to 39°. The record high is 78°, in 1999; the record low 14°, in 2019. The most rain on this date, 1.35 in, fell in 2024.
Normals 1991–2020 and records since 1987 at Memphis Wfo, 3 miles north. NOAA, through RCC-ACIS.
