23° on Nov. 13, 2019, the coldest reading for this week of the year since 1948. Next is 25° in 1963.
Fernwood’s center stands about 410 ft above sea level. Within three miles the land runs from 320 ft to 460 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Citronelle formation (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 million years old.
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, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Fernwood reaches Lake Pontchartrain and the Gulf of America by way of the Little Tangipahoa and the Tangipahoa: about 95 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fernwood; river miles along the main stem, rounded.
Fernwood has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 38° in January. About 61 inches of rain fall in a normal year.
