88° on Nov. 12, 2016, the hottest reading for this week of the year since 1913. Next is 84° in 1953.
Exeter’s center stands about 390 ft above sea level. Within three miles the land runs from 340 ft to 950 ft, a difference of 610 ft: hilly country. The highest named summit within 15 miles is Potato Hill, about 2,840 ft, 11 miles east.
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 10×. 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 12 mi of the line.
Schist, gneiss. Age: Paleoproterozoic to Cretaceous, 66 to 2,500 million years old. About 5 mi of the line.
Peridotite, serpentinite. Age: Neoproterozoic to Early Jurassic, 175 to 1,000 million years old. About 4 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Exeter reaches the Tulare Lake basin by way of Outside Creek, Elk Bayou and the Tule: about 40 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 Exeter; river miles along the main stem, rounded.
Exeter has a cold semi-arid climate. Summer afternoons average 96° in July; winter nights fall to about 36° in December. About 12 inches of rain fall in a normal year.
On November 14 Exeter normally reaches 66° and falls to 42°. The record high is 81°, in 2025; the record low 24°, in 1916. The most rain on this date, 0.98 in, fell in 1953.
Normals 1991–2020 and records since 1913 at Lindsay, 8 miles southeast. NOAA, through RCC-ACIS.
