24° on Nov. 14, 2018, the coldest reading for this week of the year since 1912. Next is 27° in 2011.
Amaya’s center stands about 580 ft above sea level. Within three miles the land runs from 540 ft to 660 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows El Pico Clay (claystone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 3 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.
Claystone. Age: Middle Eocene, 38 to 48 million years old. About 13 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 9 mi of the line.
Siltstone. Age: Middle Eocene, 38 to 48 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Amaya reaches Corpus Christi Bay and the Gulf of America by way of Turkey Creek, Soldier Slough and the Nueces: about 280 river miles.
Lake on the way: Lake Corpus Christi.
190 miles of the trip are on the Nueces.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Amaya; river miles along the main stem, rounded.
Amaya has a hot semi-arid climate. Summer afternoons average 100° in August; winter nights fall to about 38° in January. About 20 inches of rain fall in a normal year.
On November 14 Amaya normally reaches 75° and falls to 48°. The record high is 93°, in 1951; the record low 24°, in 2018. The most rain on this date, 1.18 in, fell in 1998.
Normals 1991–2020 and records since 1912 at Carrizo Springs 3 S, 16 miles south. NOAA, through RCC-ACIS.
