The Bovina plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
83° on Nov. 16, 2025, the hottest reading for this week of the year since 1927. Next is 82° in 1973.
Bovina’s center stands about 4,070 ft above sea level. Within three miles the land runs from 4,010 ft to 4,120 ft, a difference of 110 ft: gently rolling country.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. 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, less than 2.6 million years old. About 20 mi of the line.
Unconsolidated. Age: Pleistocene, 0.1 to 2.6 million years old. About 2 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 2 mi of the line.

A raindrop that lands in Bovina reaches the Gulf of America by way of the White River, the Salt Fork Brazos and the Brazos: about 1,270 river miles.
Lakes on the way: Possum Kingdom Lake and Lake Granbury.
550 miles of the trip are on the Brazos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bovina; river miles along the main stem, rounded.
Bovina has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 22° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 19 inches of water.
On November 14 Bovina normally reaches 61° and falls to 31°. The record high is 82°, in 2025; the record low 12°, in 2018. The most rain on this date, 0.49 in, fell in 2004.
