34° on Nov. 14, 2022, the coldest reading for this week of the year since 1996. Next is 35° in 2024.
Fremont’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 750 ft, a difference of 750 ft: hilly country. The highest named summit within 15 miles is Rose Peak, about 3,770 ft, 15 miles east.
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 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.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 11 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 3 mi of the line.
Melange. Age: Jurassic to Cretaceous, 66 to 202 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.
Siltstone-mudstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 1 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 0.9 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.

Rain that falls on Fremont runs only a short way, about 3 miles, to San Francisco Bay and the Pacific Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fremont; river miles along the main stem, rounded.
Fremont has a warm-summer Mediterranean climate. Summer afternoons average 78° in July; winter nights fall to about 42° in January. About 16 inches of rain fall in a normal year.
On November 14 Fremont normally reaches 65° and falls to 46°. The record high is 79°, in 2010; the record low 34°, in 2022. The most rain on this date, 0.51 in, fell in 2006.
