91° on Nov. 12, 2003, the hottest reading for this week of the year since 1911. Next is 88° in 1938.
Adel’s center stands about 240 ft above sea level. Within three miles the land runs from 210 ft to 290 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Miccosukee Formation (clay, sand, gravel), from the Tertiary Neogene, 2.6 to 23 million years old.
The section below crosses 2 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.
Clay, sand, gravel. Age: Tertiary Neogene, 2.6 to 23 million years old. About 19 mi of the line.
Dolostone, sand, clay. Age: Miocene, 5.3 to 23 million years old. About 6 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 Adel reaches the Gulf of America by way of Bear Creek, the Withlacoochee and the Suwannee: about 230 river miles.
130 miles of the trip are on the Suwannee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Adel; river miles along the main stem, rounded.
Adel has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 39° in January. About 50 inches of rain fall in a normal year.
On November 14 Adel normally reaches 69° and falls to 47°. The record high is 88°, in 1938; the record low 27°, in 1968. The most rain on this date, 2.68 in, fell in 2018.
