84° on Nov. 11, 2016, the hottest reading for this week of the year since 1881. Next is 83° in 1900.
Del Rey’s center stands about 340 ft above sea level. Within three miles the land runs from 320 ft to 360 ft, a difference of 40 ft: nearly flat ground. The highest named summit within 15 miles is Jesse Morrow Mountain, about 2,070 ft, 12 miles east-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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 44×. 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 19 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Diorite, gabbro. Age: Triassic to Cretaceous, 66 to 252 million years old. About 0.5 mi of the line.

Del Rey has a hot semi-arid climate. Summer afternoons average 98° in July; winter nights fall to about 40° in December. About 11 inches of rain fall in a normal year.
On November 14 Del Rey normally reaches 65° and falls to 46°. The record high is 79°, in 1948; the record low 30°, in 1916. The most rain on this date, 1.35 in, fell in 1953.
