3.02 inches of rain fell in two days, the most for this week of the year since records began in 1923. The next wettest, 3.00 inches, fell in 2014.
Guin’s center stands about 450 ft above sea level. Within three miles the land runs from 410 ft to 720 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Bee Mountain, about 880 ft, 11 miles north-northeast.
Under the town center the state geologic map shows Alluvial, coastal and low terrace deposits (sand), from the Holocene, less than 12,000 years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. 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: Cretaceous, 66 to 145 million years old. About 15 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 7 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.

A raindrop that lands in Guin reaches Mobile Bay and the Gulf of America by way of Little Creek, Purgatory Creek, Beaver Creek, the Buttahatchee, the Tombigbee and the Mobile: about 430 river miles.
310 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Guin; river miles along the main stem, rounded.
Guin has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 30° in January. About 64 inches of rain fall in a normal year.
On November 14 Guin normally reaches 64° and falls to 39°. The record high is 80°, in 1985; the record low 20°, in 2019. The most rain on this date, 2.95 in, fell in 2024.
Normals 1991–2020 and records since 1923 at Winfield 2 SW, 5 miles southeast. NOAA, through RCC-ACIS.
