The Bermuda Dunes 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.
25° on Nov. 11, 1950, the coldest reading for this week of the year since 1894. Next is 25° in 1958.
Bermuda Dunes’s center stands about 90 ft above sea level. Within three miles the land runs from 10 ft to 280 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Martinez Mountain, about 6,500 ft, 13 miles south-southwest.
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 4×. 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 8 mi of the line.
Gneiss. Age: Paleoproterozoic to Miocene, 5.3 to 2,500 million years old. About 5 mi of the line.
Plutonic, gneiss. Age: Paleoproterozoic to Late Cretaceous, 66 to 2,500 million years old. About 4 mi of the line.
Tonalite. Age: Middle Jurassic to Late Cretaceous, 66 to 175 million years old. About 3 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 2 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.

Bermuda Dunes has a hot desert climate. Summer afternoons average 106° in July; winter nights fall to about 45° in December. About 3 inches of rain fall in a normal year.
On November 14 Bermuda Dunes normally reaches 79° and falls to 53°. The record high is 95°, in 1967; the record low 32°, in 1932. The most rain on this date, 0.25 in, fell in 1918.
