89° on Nov. 14, 1989, the hottest reading for this week of the year since 1898. Next is 89° in 2025.
Grapevine’s center stands about 640 ft above sea level. Within three miles the land runs from 510 ft to 680 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Eagle Ford Formation (black-shale, siltstone), from the Late Cretaceous, 66 to 100 million 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 61×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale, siltstone. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.
Sandstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Marlstone, limestone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.5 mi of the line.

A raindrop that lands in Grapevine reaches Galveston Bay and the Gulf of America by way of Cottonwood Branch, Denton Creek, the Elm Fork Trinity and the Trinity: about 490 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 Grapevine; river miles along the main stem, rounded.
Grapevine 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 Grapevine 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.
Normals 1991–2020 and records since 1898 from the Dallas-Fort Worth Area threaded record (Dal-Ftw Wscmo Airport, 4 miles southeast). NOAA, through RCC-ACIS.
