87° on Nov. 15, 2025, the hottest reading for this week of the year since 1948. Next is 86° in 1999.
North Richland Hills’s center stands about 610 ft above sea level. Within three miles the land runs from 490 ft to 670 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Blue Mound, about 840 ft, 10 miles northwest.
Under the town center the state geologic map shows Grayson Marl and Main Street Limestone, undivided (marlstone, limestone), from the Early Cretaceous to Late Cretaceous, 66 to 145 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 51×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 145 million years old. About 4 mi of the line.
Claystone. Age: Early Cretaceous, 100 to 145 million years old. About 3 mi of the line.
Sandstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.
Marlstone, limestone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 1 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 North Richland Hills reaches Galveston Bay and the Gulf of America by way of Calloway Branch, Walker Branch, 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 North Richland Hills; river miles along the main stem, rounded.
North Richland Hills has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 36° in January. About 38 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 North Richland Hills normally reaches 66° and falls to 46°. The record high is 86°, in 1999; the record low 23°, in 2018. The most rain on this date, 1.80 in, fell in 1994.
Normals 1991–2020 and records since 1948 at Fort Worth Wsfo, 4 miles west. NOAA, through RCC-ACIS.
