89° on Nov. 14, 2010, the hottest reading for this week of the year since 1950. Next is 82° in 2025.
Pinole’s center stands about 130 ft above sea level. Within three miles the land runs from 0 ft to 630 ft, a difference of 630 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Vollmer Peak, about 1,890 ft, 9 miles south-southeast.
Under the town center the state geologic map shows Miocene marine rocks (sandstone, mudstone), from the Oligocene to Pliocene, 2.6 to 34 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 17×. 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: Oligocene to Pliocene, 2.6 to 34 million years old. About 12 mi of the line.
Sandstone, mudstone. Age: Paleocene, 56 to 66 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 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.

A raindrop that lands in Pinole reaches San Francisco Bay and the Pacific Ocean by way of Garrity Creek: about 1 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pinole; river miles along the main stem, rounded.
Pinole has a warm-summer Mediterranean climate. Summer afternoons average 75° in September; winter nights fall to about 44° in January. About 24 inches of rain fall in a normal year.
On November 14 Pinole normally reaches 65° and falls to 49°. The record high is 89°, in 2010; the record low 34°, in 1985. The most rain on this date, 1.53 in, fell in 1952.
Normals 1991–2020 and records since 1950 at Richmond, 7 miles southwest, 110 ft lower. NOAA, through RCC-ACIS.
