89° on Nov. 11, 1921, the hottest reading for this week of the year since 1902. Next is 86° in 2019.
Gustine’s center stands about 100 ft above sea level. Within three miles the land runs from 70 ft to 140 ft, a difference of 70 ft: gently rolling country. The highest named summit within 15 miles is Bone Spring Hill, about 2,490 ft, 15 miles west-southwest.
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 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 14 mi of the line.
Sandstone, siltstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Sand. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Sandstone, mudstone. Age: Paleocene, 56 to 66 million years old. About 0.6 mi of the line.

A raindrop that lands in Gustine reaches San Francisco Bay and the Pacific Ocean by way of Los Banos Creek, the San Joaquin and New York Slough: about 130 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gustine; river miles along the main stem, rounded.
Gustine has a hot semi-arid climate. Summer afternoons average 100° in July; winter nights fall to about 38° in January. About 12 inches of rain fall in a normal year.
On November 14 Gustine normally reaches 71° and falls to 43°. The record high is 83°, in 1921; the record low 21°, in 1916. The most rain on this date, 1.25 in, fell in 1965.
Normals 1991–2020 and records since 1902 at Newman, 2 miles north-northwest. NOAA, through RCC-ACIS.
