86° on Nov. 14, 2017, the hottest reading for this week of the year since 1946. Next is 85° in 2025.
Fabens’s center stands about 3,620 ft above sea level. Within three miles the land runs from 3,590 ft to 3,840 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Backbone Hill, about 4,200 ft, 15 miles north-northeast.
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 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 30×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Fine-detrital, sand. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 4 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.7 mi of the line.

A raindrop that lands in Fabens reaches the Gulf of America by way of the Rio Grande: about 1,220 river miles.
Lakes on the way: Paz Ramirez Lake and Amistad Reservoir.
610 miles of the trip are on the Rio Grande.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fabens; river miles along the main stem, rounded.
Fabens has a cold desert climate. Summer afternoons average 98° in June; winter nights fall to about 29° in January. About 8 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Fabens normally reaches 70° and falls to 36°. The record high is 86°, in 2017; the record low 19°, in 2018. The most rain on this date, 0.59 in, fell in 2004.
Normals 1991–2020 and records since 1946 at Tornillo 2 SSE, 9 miles southeast. NOAA, through RCC-ACIS.
