75° on Nov. 12, 1967, the hottest reading for this week of the year since 1874. Next is 74° in 1973.
West Jordan’s center stands about 4,380 ft above sea level. Within three miles the land runs from 4,280 ft to 4,620 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Twin Peaks, about 11,240 ft, 12 miles east.
Under the town center the state geologic map shows Lake Bonneville deposits (clay), from the Pleistocene, less than 2.6 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 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay. Age: Pleistocene, less than 2.6 million years old. About 14 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Granodiorite. Age: Middle Eocene to Early Oligocene, 30 to 42 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous to Permian, 273 to 324 million years old. About 2 mi of the line.
Unconsolidated. Age: Pleistocene, less than 2.6 million years old. About 0.8 mi of the line.

A raindrop that lands in West Jordan reaches Great Salt Lake by way of Bingham Creek and the Jordan: about 30 river miles. Great Salt Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of West Jordan; river miles along the main stem, rounded.
West Jordan has a dry-summer hot-summer continental climate. Summer afternoons average 94° in July; winter nights fall to about 24° in January. A normal year brings about 52 inches of snow; with the rain, that comes to about 16 inches of water.
On November 14 West Jordan normally reaches 52° and falls to 33°. The record high is 71°, in 1967; the record low 3°, in 1955. The most rain on this date, 0.71 in, fell in 1955.
Normals 1991–2020 and records since 1874 from the Salt Lake City Area threaded record (Salt Lake City International Airport, 11 miles north, 150 ft lower). NOAA, through RCC-ACIS.
