89° on Nov. 14, 1989, the hottest reading for this week of the year since 1898. Next is 89° in 2025.
Arlington’s center stands about 610 ft above sea level. Within three miles the land runs from 520 ft to 670 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Inspiration Point, about 870 ft, 13 miles south-southeast.
Under the town center the state geologic map shows Woodbine Formation (sandstone-mudstone), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 7 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.
Sandstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 6 mi of the line.
Black-shale, siltstone. Age: Late Cretaceous, 66 to 100 million years old. About 6 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 5 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Claystone. Age: Early Cretaceous, 100 to 145 million years old. About 2 mi of the line.
Marlstone, chalk. Age: Late Cretaceous, 66 to 100 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Arlington reaches Galveston Bay and the Gulf of America by way of Johnson Creek, the West Fork Trinity and the Trinity: about 480 river miles.
Lake on the way: Woodlands Golf Course Lake.
270 miles of the trip are on the Trinity.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Arlington; river miles along the main stem, rounded.
Arlington has a humid subtropical climate. Summer afternoons average 96° in July; winter nights fall to about 36° in January. About 37 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Arlington normally reaches 67° and falls to 47°. The record high is 89°, in 1989; the record low 21°, in 1916. The most rain on this date, 1.82 in, fell in 1994.
