27° on Nov. 12, 1985, the coldest reading for this week of the year since 1895. Next is 29° in 1987.
Timber Cove’s center stands about 640 ft above sea level. Within three miles the land runs from 10 ft to 1,540 ft, a difference of 1,530 ft: steep hill country. Open water lies within three miles. The highest named summit within 15 miles is Big Mountain, about 2,640 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Tertiary-Cretaceous Coastal Belt Rocks (sandstone, mudstone), from the Late Cretaceous to Pliocene, 2.6 to 100 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. 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: Late Cretaceous to Pliocene, 2.6 to 100 million years old. About 4 mi of the line.
Melange. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 4 mi of the line.
Serpentinite. Age: Middle Jurassic to Late Jurassic, 145 to 175 million years old. About 3 mi of the line.
Greenstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 2 mi of the line.
Sandstone, mudstone. Age: Paleocene to Middle Eocene, 38 to 66 million years old. About 0.8 mi of the line.

Rain that falls on Timber Cove runs only a short way, about 2 miles, to the Pacific Ocean.

Timber Cove has a warm-summer Mediterranean climate. Summer afternoons average 67° in August; winter nights fall to about 42° in January. About 39 inches of rain fall in a normal year.
On November 14 Timber Cove normally reaches 61° and falls to 44°. The record high is 73°, in 1990; the record low 30°, in 1985. The most rain on this date, 2.10 in, fell in 1972.
