89° on Nov. 15, 2008, the hottest reading for this week of the year since 1937. Next is 89° in 2019.
Live Oak’s center stands about 110 ft above sea level. Within three miles the land runs from 10 ft to 640 ft, a difference of 630 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Loma Prieta, about 3,780 ft, 11 miles northeast.
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 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 7 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 2 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone, siltstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 million years old. About 0.8 mi of the line.
Serpentinite. Age: Middle Jurassic to Late Jurassic, 145 to 175 million years old. About 0.6 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 Live Oak runs straight into the Pacific Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Live Oak; river miles along the main stem, rounded.
Live Oak has a warm-summer Mediterranean climate. Summer afternoons average 90° in August; winter nights fall to about 37° in January. About 50 inches of rain fall in a normal year.
On November 14 Live Oak normally reaches 72° and falls to 40°. The record high is 88°, in 2021; the record low 27°, in 1985. The most rain on this date, 3.42 in, fell in 1972.
Normals 1991–2020 and records since 1937 at Ben Lomond No. 4, 9 miles northwest, 320 ft higher. NOAA, through RCC-ACIS.
