Huron’s center stands about 450 ft above sea level. Within three miles the land runs from 400 ft to 560 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Sand Mountain, about 740 ft, 11 miles south-southeast.
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. Age: Cretaceous, 66 to 145 million years old. About 11 mi of the line.
Clay. Age: Tertiary, 2.6 to 66 million years old. About 7 mi of the line.
Sand. Age: Tertiary, 2.6 to 66 million years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Huron reaches the Gulf of America by way of the North Fork Forked Deer, the South Fork Forked Deer, the Forked Deer, the Obion and the Mississippi: about 930 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Huron; river miles along the main stem, rounded.
Huron has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 27° in January. About 55 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Huron normally reaches 61° and falls to 37°. The record high is 79°, in 1978; the record low 14°, in 2019. The most rain on this date, 1.70 in, fell in 2024.
Normals 1991–2020 and records since 1962 at Lexington, 9 miles east-northeast. NOAA, through RCC-ACIS.
