Jacinto’s center stands about 560 ft above sea level. Within three miles the land runs from 460 ft to 640 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Woodall Mountain, about 810 ft, 11 miles east.
Under the town center the state geologic map shows Coffee sand (sand, clay), from the Late Cretaceous, 66 to 100 million 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 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.
Sand, clay. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
Sand. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.

A raindrop that lands in Jacinto reaches the Gulf of America by way of Boone Creek, Hurricane Creek, the Tuscumbia River Canal, the Hatchie, Porters Creek, Cypress Creek and the Mississippi: about 990 river miles.
800 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jacinto; river miles along the main stem, rounded.
Jacinto has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 30° in January. About 59 inches of rain fall in a normal year.
On November 14 Jacinto normally reaches 62° and falls to 38°. The record high is 84°, in 1955; the record low 19°, in 2019. The most rain on this date, 3.64 in, fell in 1957.
