25° on Nov. 14, 2018, the coldest reading for this week of the year since 1948. Next is 27° in 2008.
Pleasanton’s center stands about 370 ft above sea level. Within three miles the land runs from 340 ft to 460 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Terrace deposits (sand), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 56×. 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 8 mi of the line.
Siltstone, sandstone. Age: Middle Eocene, 38 to 48 million years old. About 5 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Sandstone. Age: Eocene, 34 to 56 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. 3 smaller units along the line are not listed.

A raindrop that lands in Pleasanton reaches Corpus Christi Bay and the Gulf of America by way of Bonita Creek, the Atascosa, the Frio and the Nueces: about 170 river miles.
Lake on the way: Lake Corpus Christi.
60 miles of the trip are on the Atascosa.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pleasanton; river miles along the main stem, rounded.
Pleasanton has a humid subtropical climate. Summer afternoons average 97° in August; winter nights fall to about 40° in January. About 32 inches of rain fall in a normal year.
On November 14 Pleasanton normally reaches 74° and falls to 50°. The record high is 89°, in 2025; the record low 25°, in 2018. The most rain on this date, 0.78 in, fell in 2001.
