92° on Nov. 14, 1995, the hottest reading for this week of the year since 1942. Next is 85° in 2016.
Westside’s center stands about 240 ft above sea level. Within three miles the land runs from 210 ft to 260 ft, a difference of 50 ft: nearly flat ground.
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 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. 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 23 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Westside reaches San Francisco Bay and the Pacific Ocean by way of the San Joaquin and New York Slough: about 230 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Westside; river miles along the main stem, rounded.
Westside has a cold desert climate. Summer afternoons average 99° in July; winter nights fall to about 36° in December. Barely 0.0 inches of rain fall in a normal year.
On November 14 Westside normally reaches 70° and falls to 42°. The record high is 92°, in 1995; the record low 28°, in 1961. The most rain on this date, 1.25 in, fell in 1953.
Normals 1991–2020 and records since 1942 at Five Points 5 SSW, 3 miles south-southwest. NOAA, through RCC-ACIS.
