87° on Nov. 11, 1956, the hottest reading for this week of the year since 1895. Next is 86° in 1900.
East Orosi’s center stands about 390 ft above sea level. Within three miles the land runs from 350 ft to 1,000 ft, a difference of 650 ft: hilly country. The highest named summit within 15 miles is Bear Mountain, about 4,100 ft, 12 miles east-northeast.
Under the town center the state geologic map shows Older Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 9 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 8 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Schist, gneiss. Age: Paleoproterozoic to Cretaceous, 66 to 2,500 million years old. About 1 mi of the line.

A raindrop that lands in East Orosi reaches the Tulare Lake basin by way of Cottonwood Creek and the Tule: about 55 river miles. The Tulare Lake basin has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Often dry. About 80% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
A lake that comes back. The bed of Tulare Lake is farmland now; in very wet years it floods again.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of East Orosi; river miles along the main stem, rounded.
East Orosi has a cold semi-arid climate. Summer afternoons average 94° in July; winter nights fall to about 38° in January. About 10 inches of rain fall in a normal year.
On November 14 East Orosi normally reaches 65° and falls to 44°. The record high is 85°, in 1986; the record low 24°, in 1911. The most rain on this date, 0.90 in, fell in 1955.
Normals 1991–2020 and records since 1895 at Visalia, 15 miles south. NOAA, through RCC-ACIS.
