18° on Nov. 13, 2019, the coldest reading for this week of the year since 1895. Next is 19° in 1940.
Homewood’s center stands about 680 ft above sea level. Within three miles the land runs from 570 ft to 1,100 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Signal Mountain, about 1,560 ft, 14 miles east-southeast.
Under the town center the state geologic map shows Floyd Shale, from the Carboniferous, 324 to 359 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone, shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Limestone, shale. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units along the line are not listed.

A raindrop that lands in Homewood reaches Mobile Bay and the Gulf of America by way of Griffin Brook, Shades Creek, the Cahaba, the Alabama and the Mobile: about 390 river miles.
200 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Homewood; river miles along the main stem, rounded.
Homewood has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 35° in January. About 57 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Homewood normally reaches 65° and falls to 43°. The record high is 82°, in 1955; the record low 23°, in 2014. The most rain on this date, 4.43 in, fell in 1929.
