90° on Nov. 17, 2011, the hottest reading for this week of the year since 1959. Next is 88° in 1995.
Aransas Pass’s center stands barely above sea level. Within three miles the land runs from 0 ft to 10 ft, a difference of 10 ft: nearly flat ground. Open water lies within three miles.
Under the town center the state geologic map shows Alluvium (fine-detrital, coarse-detrital), from the Holocene, less than 12,000 years old.
The section below crosses 6 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 to Holocene, less than 2.6 million years old. About 4 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 0.5 mi of the line.
Sand, fine-detrital. Age: Holocene, less than 12,000 years old. About 0.3 mi of the line.

Aransas Pass has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 46° in January. About 36 inches of rain fall in a normal year.
On November 14 Aransas Pass normally reaches 75° and falls to 57°. The record high is 87°, in 2024; the record low 35°, in 1959. The most rain on this date, 0.75 in, fell in 1998.
