5.51 inches of rain fell in two days, the most for this week of the year since records began in 1905. The next wettest, 4.69 inches, fell in 2025.
Ojai’s center stands about 770 ft above sea level. Within three miles the land runs from 600 ft to 3,540 ft, a difference of 2,940 ft: mountain country. The highest named summit within 15 miles is Reyes Peak, about 7,480 ft, 13 miles north.
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 3×. 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 9 mi of the line.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 7 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Middle Eocene to Early Miocene, 16 to 48 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 0.8 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 Ojai reaches the Pacific Ocean by way of San Antonio Creek and the Ventura: about 16 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ojai; river miles along the main stem, rounded.
Ojai has a hot-summer Mediterranean climate. Summer afternoons average 91° in August; winter nights fall to about 33° in December. About 21 inches of rain fall in a normal year.
On November 14 Ojai normally reaches 73° and falls to 38°. The record high is 100°, in 1906; the record low 25°, in 1916. The most rain on this date, 2.75 in, fell in 1953.
