26° on Nov. 14, 2000, the coldest reading for this week of the year since 1974. Next is 28° in 1994.
Hidden Meadows’s center stands about 1,600 ft above sea level. Within three miles the land runs from 470 ft to 1,670 ft, a difference of 1,200 ft: steep hill country. The highest named summit within 15 miles is Boucher Hill, about 5,450 ft, 14 miles east-northeast.
Under the town center the state geologic map shows Mesozoic gabbroic rocks, unit 2 (undivided) (diorite, gabbro), from the Triassic to Cretaceous, 66 to 252 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 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Tonalite. Age: Middle Jurassic to Late Cretaceous, 66 to 175 million years old. About 11 mi of the line.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 million years old. About 6 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Late Jurassic to Early Cretaceous, 100 to 164 million years old. About 2 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Diorite, gabbro. Age: Triassic to Cretaceous, 66 to 252 million years old. About 2 mi of the line.
Argillite. Age: Paleozoic to Late Jurassic, 145 to 542 million years old. About 1 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 Hidden Meadows reaches the Pacific Ocean by way of the San Luis Rey: about 25 river miles.
Often dry. About 100% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hidden Meadows; river miles along the main stem, rounded.
Hidden Meadows has a hot-summer Mediterranean climate. Summer afternoons average 91° in August; winter nights fall to about 36° in December. About 15 inches of rain fall in a normal year.
On November 14 Hidden Meadows normally reaches 73° and falls to 41°. The record high is 92°, in 2021; the record low 26°, in 2000. The most rain on this date, 0.30 in, fell in 1993.
Normals 1991–2020 and records since 1974 from the Ramona Area threaded record (Ramona Airport, 17 miles southeast, 220 ft lower). NOAA, through RCC-ACIS.
