Clyde’s center stands about 1,990 ft above sea level. Within three miles the land runs from 1,930 ft to 2,040 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Eagle Mountain, about 2,210 ft, 10 miles south-southwest.
Under the town center the state geologic map shows Antlers Sand (sandstone, claystone), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 14 mi of the line.
Limestone, shale. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Shale. Age: Permian, 252 to 299 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Clyde reaches the Gulf of America by way of Kaiser Creek, North Prong Pecan Bayou, Pecan Bayou and the Colorado: about 630 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls, Brownwood Lake and Lake Lyndon B Johnson.
320 miles of the trip are on the Colorado.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clyde; river miles along the main stem, rounded.
Clyde has a humid subtropical climate. Summer afternoons average 96° in July; winter nights fall to about 34° in January. About 25 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Clyde normally reaches 68° and falls to 44°. The record high is 89°, in 2025; the record low 14°, in 1976. The most rain on this date, 1.54 in, fell in 1954.
Normals 1991–2020 and records since 1885 from the Abilene Area threaded record (Abilene Regional Airport, 11 miles west, 200 ft lower). NOAA, through RCC-ACIS.
