3.29 inches of rain fell in two days, the most for this week of the year since records began in 1906. The next wettest, 3.22 inches, fell in 1981.
Menlo Park’s center stands about 14 ft above sea level. Within three miles the land runs from 0 ft to 80 ft, a difference of 80 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Black Mountain, about 2,810 ft, 11 miles south.
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 48×. 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, less than 2.6 million years old. About 8 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 5 mi of the line.

Rain that falls on Menlo Park runs straight into San Francisco Bay and the Pacific Ocean.

Menlo Park has a warm-summer Mediterranean climate. Summer afternoons average 81° in July; winter nights fall to about 40° in January. About 19 inches of rain fall in a normal year.
On November 14 Menlo Park normally reaches 65° and falls to 44°. The record high is 79°, in 2010; the record low 29°, in 1935. The most rain on this date, 1.72 in, fell in 1953.
