The Palm Desert 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.
23° on Nov. 17, 1964, the coldest reading for this week of the year since 1922. Next is 31° in 1950.
Palm Desert’s center stands about 220 ft above sea level. Within three miles the land runs from 130 ft to 1,660 ft, a difference of 1,530 ft: steep hill country. The highest named summit within 15 miles is Toro Peak, about 8,660 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 6 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.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 9 mi of the line.
Tonalite. Age: Middle Jurassic to Late Cretaceous, 66 to 175 million years old. About 6 mi of the line.
Sand. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Schist, gneiss. Age: Paleoproterozoic to Cretaceous, 66 to 2,500 million years old. About 3 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 2 mi of the line.
Plutonic, gneiss. Age: Paleoproterozoic to Late Cretaceous, 66 to 2,500 million years old. About 1 mi of the line.

Palm Desert has a hot desert climate. Summer afternoons average 109° in July; winter nights fall to about 46° in December. About 5 inches of rain fall in a normal year.
On November 14 Palm Desert normally reaches 79° and falls to 54°. The record high is 93°, in 2021; the record low 31°, in 1964. The most rain on this date, 0.50 in, fell in 1946.
