85° on Nov. 13, 1964, the hottest reading for this week of the year since 1889. Next is 84° in 1921.
Chunky’s center stands about 330 ft above sea level. Within three miles the land runs from 290 ft to 490 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Mount Barton, about 560 ft, 13 miles east.
The section below crosses 6 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.

A raindrop that lands in Chunky reaches the Gulf of America by way of the Chunky, the Chickasawhay, the Pascagoula and the West Pascagoula: about 260 river miles.
160 miles of the trip are on the Chickasawhay.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chunky; river miles along the main stem, rounded.
Chunky has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 36° in January. About 57 inches of rain fall in a normal year.
On November 14 Chunky normally reaches 69° and falls to 43°. The record high is 84°, in 1921; the record low 21°, in 1963. The most rain on this date, 2.07 in, fell in 1929.
