91° on Nov. 15, 2025, the hottest reading for this week of the year since 1910. Next is 88° in 1965.
Girard’s center stands about 2,130 ft above sea level. Within three miles the land runs from 2,030 ft to 2,210 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Red Hill, about 2,320 ft, 8 miles north.
Under the town center the state geologic map shows Whitehorse Group, undivided (sandstone, shale), from the Permian, 252 to 299 million years old.
The section below crosses 5 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.
Sandstone, shale. Age: Permian, 252 to 299 million years old. About 11 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 5 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Girard reaches the Gulf of America by way of Duck Creek, the Salt Fork Brazos and the Brazos: about 1,030 river miles.
Lakes on the way: Possum Kingdom Lake and Lake Granbury.
550 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Girard; river miles along the main stem, rounded.
Girard has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 28° in January. About 23 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Girard normally reaches 67° and falls to 38°. The record high is 86°, in 2025; the record low 12°, in 1976. The most rain on this date, 0.22 in, fell in 2004.
