90° on Nov. 15, 2025, the hottest reading for this week of the year since 1911. Next is 88° in 2017.
Petersburg’s center stands about 3,260 ft above sea level. Within three miles the land runs from 3,200 ft to 3,270 ft, a difference of 70 ft: gently rolling country.
The section below crosses 2 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: Pleistocene, less than 2.6 million years old. About 24 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 0.3 mi of the line.

A raindrop that lands in Petersburg reaches the Gulf of America by way of Crawfish Creek, the White River, the Salt Fork Brazos and the Brazos: about 1,120 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 Petersburg; river miles along the main stem, rounded.
Petersburg has a cold semi-arid climate. Summer afternoons average 93° in July; winter nights fall to about 27° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 18 inches of water.
On November 14 Petersburg normally reaches 64° and falls to 37°. The record high is 89°, in 2025; the record low 4°, in 1976. The most rain on this date, 1.57 in, fell in 1968.
