98° on Nov. 11, 2006, the hottest reading for this week of the year since 1901. Next is 94° in 1910.
Nordheim’s center stands about 410 ft above sea level. Within three miles the land runs from 310 ft to 440 ft, a difference of 130 ft: gently rolling country.
The section below crosses 4 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.
Clay, sandstone. Age: Miocene, 5.3 to 23 million years old. About 16 mi of the line.
Sandstone, clay. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.
Clay, sandstone. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.5 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 Nordheim reaches the Gulf of America by way of Cabeza Creek, the San Antonio, the Guadalupe and the South Guadalupe: about 120 river miles.
80 miles of the trip are on the San Antonio.
Often dry. About 30% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Nordheim; river miles along the main stem, rounded.
Nordheim has a humid subtropical climate. Summer afternoons average 98° in August; winter nights fall to about 42° in January. About 34 inches of rain fall in a normal year.
On November 14 Nordheim normally reaches 76° and falls to 50°. The record high is 91°, in 2005; the record low 26°, in 2018. The most rain on this date, 0.90 in, fell in 1902.
Normals 1991–2020 and records since 1901 at Cuero, 20 miles northeast, 200 ft lower. NOAA, through RCC-ACIS.
