Garner’s center stands about 960 ft above sea level. Within three miles the land runs from 850 ft to 1,140 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Slipdown Mountain, about 1,370 ft, 9 miles north-northeast.
Under the town center the state geologic map shows Twin Mountains Formation (claystone, sandstone), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. 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 Garner reaches the Gulf of America by way of Dry Creek, Rock Creek and the Brazos: about 620 river miles.
Lake on the way: Lake Granbury.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Garner; river miles along the main stem, rounded.
Garner has a humid subtropical climate. Summer afternoons average 96° in July; winter nights fall to about 33° in January. About 32 inches of rain fall in a normal year.
On November 14 Garner normally reaches 68° and falls to 43°. The record high is 87°, in 1989; the record low 19°, in 2018. The most rain on this date, 2.36 in, fell in 1994.
Normals 1991–2020 and records since 1948 at Mineral Wells Airport, 5 miles southwest. NOAA, through RCC-ACIS.
