Baywood Park’s center stands about 450 ft above sea level. Within three miles the land runs from 10 ft to 1,070 ft, a difference of 1,060 ft: steep hill country. The highest named summit within 15 miles is Morena Sierra, about 2,450 ft, 8 miles south-southeast.
Under the town center the state geologic map shows Franciscan melange, from the Jurassic to Cretaceous, 66 to 202 million years old.
The section below crosses 9 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.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 million years old. About 5 mi of the line.
Melange. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 3 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 2 mi of the line.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 2 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Sandstone, mudstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
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 Baywood Park reaches San Francisco Bay and the Pacific Ocean by way of Polhemus Creek and San Mateo Creek: about 6 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Baywood Park; river miles along the main stem, rounded.
Baywood Park has a warm-summer Mediterranean climate. Summer afternoons average 75° in September; winter nights fall to about 44° in January. About 20 inches of rain fall in a normal year.
On November 14 Baywood Park normally reaches 65° and falls to 49°. The record high is 78°, in 2008; the record low 36°, in 1978. The most rain on this date, 1.04 in, fell in 1968.
Normals 1991–2020 and records since 1945 from the San Francisco Airport Area threaded record (San Francisco International Airport, 6 miles north-northwest, 440 ft lower). NOAA, through RCC-ACIS.
