The Abbeville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
11° on Nov. 13, 2019, the coldest reading for this week of the year since 1893. Next is 15° in 1940.
Abbeville’s center stands about 400 ft above sea level. Within three miles the land runs from 250 ft to 490 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Thacker Mountain, about 630 ft, 13 miles south-southwest.
Under the town center the state geologic map shows Tallahatta formation and Neshoba sand (claystone, clay), from the Eocene, 34 to 56 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 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, clay. Age: Eocene, 34 to 56 million years old. About 23 mi of the line.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 1 mi of the line.

A raindrop that lands in Abbeville reaches the Gulf of America by way of the Little Tallahatchie, the Tallahatchie, the Yazoo and the Mississippi: about 760 river miles.
450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Abbeville; river miles along the main stem, rounded.
Abbeville has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 30° in January. About 60 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Abbeville normally reaches 65° and falls to 40°. The record high is 86°, in 1955; the record low 12°, in 2019. The most rain on this date, 4.70 in, fell in 1957.
