3.80 inches of rain fell in two days, the most for this week of the year since records began in 1971. The next wettest, 3.19 inches, fell in 2017.
Heceta Beach’s center stands about 50 ft above sea level. Within three miles the land runs from 0 ft to 330 ft, a difference of 330 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Saddle Mountain, about 2,390 ft, 13 miles northeast.
Under the town center the state geologic map shows Lacustrine and fluvial sedimentary rocks (clay, silt, sand), from the Pleistocene, less than 2.6 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 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt. Age: Late Eocene, 34 to 38 million years old. About 8 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Siltstone, sandstone. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 0.7 mi of the line.

Rain that falls on Heceta Beach runs straight into the Pacific Ocean.

Heceta Beach has a warm-summer Mediterranean climate. Summer afternoons average 67° in July; winter nights fall to about 38° in February. About 68 inches of rain fall in a normal year.
On November 14 Heceta Beach normally reaches 53° and falls to 42°. The record high is 67°, in 1999; the record low 26°, in 1978. The most rain on this date, 2.00 in, fell in 1973.
