96° on Nov. 13, 1933, the hottest reading for this week of the year since 1877. Next is 94° in 1900.
West Hollywood’s center stands about 290 ft above sea level. Within three miles the land runs from 130 ft to 1,350 ft, a difference of 1,220 ft: steep hill country. The highest named summit within 15 miles is Mount Lukens, about 5,060 ft, 14 miles north-northeast.
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 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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 11 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 3 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 3 mi of the line.
Basalt, andesite. Age: Late Oligocene to Late Miocene, 8 to 25 million years old. About 0.7 mi of the line.
Plutonic. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 0.6 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 West Hollywood reaches the Pacific Ocean by way of Ballona Creek: about 6 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of West Hollywood; river miles along the main stem, rounded.
West Hollywood has a hot semi-arid climate. Summer afternoons average 84° in August; winter nights fall to about 48° in December. About 14 inches of rain fall in a normal year.
On November 14 West Hollywood normally reaches 73° and falls to 54°. The record high is 93°, in 1933; the record low 36°, in 1880. The most rain on this date, 1.33 in, fell in 1928.
