96° on Nov. 12, 2021, the hottest reading for this week of the year since 1893. Next is 94° in 2019.
Encinitas’s center stands about 90 ft above sea level. Within three miles the land runs from 0 ft to 380 ft, a difference of 380 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Mount Whitney, about 1,690 ft, 9 miles east-northeast.
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 17×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 million years old. About 5 mi of the line.
Diorite, gabbro. Age: Triassic to Cretaceous, 66 to 252 million years old. About 3 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Late Jurassic to Early Cretaceous, 100 to 164 million years old. About 1 mi of the line.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Encinitas reaches the Pacific Ocean by way of San Marcos Creek: about 5 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Encinitas; river miles along the main stem, rounded.
Encinitas has a hot semi-arid climate. Summer afternoons average 89° in August; winter nights fall to about 44° in December. About 14 inches of rain fall in a normal year.
On November 14 Encinitas normally reaches 75° and falls to 50°. The record high is 93°, in 1949; the record low 24°, in 1938. The most rain on this date, 1.47 in, fell in 1950.
Normals 1991–2020 and records since 1893 from the Escondido Area threaded record (Escondido No. 2, 13 miles east-northeast, 510 ft higher). NOAA, through RCC-ACIS.
