17° on Nov. 13, 2019, the coldest reading for this week of the year since 1909. Next is 20° in 1916.
Broaddus’s center stands about 270 ft above sea level. Within three miles the land runs from 150 ft to 360 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Moss Hill, about 460 ft, 12 miles southwest.
Under the town center the state geologic map shows Yegua Formation (claystone, sandstone), from the Eocene, 34 to 56 million years old.
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.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 10 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 5 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Sandstone-mudstone. Age: Late Eocene, 34 to 38 million years old. About 2 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 1 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 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 Broaddus reaches the Gulf of America by way of Ester Lake, the Angelina and the Neches: about 190 river miles.
Lakes on the way: Ester Lake, Sabine Lake and B A Steinhagen Lake.
110 miles of the trip are on the Neches.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Broaddus; river miles along the main stem, rounded.
Broaddus has a humid subtropical climate. Summer afternoons average 94° in August; winter nights fall to about 35° in January. About 56 inches of rain fall in a normal year.
On November 14 Broaddus normally reaches 70° and falls to 44°. The record high is 86°, in 2005; the record low 24°, in 2019. The most rain on this date, 1.82 in, fell in 1998.
Normals 1991–2020 and records since 1909 at San Augustine, 17 miles north-northeast. NOAA, through RCC-ACIS.
