84° on Nov. 17, 2008, the hottest reading for this week of the year since 1904. Next is 83° in 1949.
Nipinnawasee’s center stands about 2,920 ft above sea level. Within three miles the land runs from 1,940 ft to 4,860 ft, a difference of 2,920 ft: mountain country. The highest named summit within 15 miles is Iron Mountain, about 9,130 ft, 14 miles east-northeast.
Under the town center the state geologic map shows Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges) (granodiorite), from the Permian to Tertiary, 2.6 to 260 million years old.
The section below crosses 2 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.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 23 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 Nipinnawasee reaches San Francisco Bay and the Pacific Ocean by way of Peterson Creek, Miami Creek, the Fresno, the Eastside Bypass, Sand Slough, Mariposa Slough, the San Joaquin and New York Slough: about 240 river miles.
140 miles of the trip are on the San Joaquin.
Often dry. About 30% 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 Nipinnawasee; river miles along the main stem, rounded.
Nipinnawasee has a hot-summer Mediterranean climate. Summer afternoons average 95° in July; winter nights fall to about 32° in January. About 33 inches of rain fall in a normal year.
On November 14 Nipinnawasee normally reaches 65° and falls to 37°. The record high is 82°, in 1990; the record low 23°, in 1993. The most rain on this date, 3.20 in, fell in 1981.
Normals 1991–2020 and records since 1904 at North Fork Rs, 17 miles southeast, 280 ft lower. NOAA, through RCC-ACIS.
