Foss, Oregon

Foss is an unincorporated community in Tillamook County, Oregon, United States. It is about 4 mi east of Mohler and Oregon Route 53, near the Nehalem River. Foss is the site of an important river flood gauge.

Foss was named for Herbert Foss, who owned timber in the area. Foss post office ran from 1928 to 1943, and Foss station on the Southern Pacific Railroad (now the Port of Tillamook Bay Railroad) was established shortly after the post office. Camp Nehalem (also known as Camp Foss), a Civilian Conservation Corps (CCC) camp northeast of Foss, had a Foss mailing address.

Geography
Foss is only 474 acres in area. It lies in the Northwestern region of Oregon at a low elevation near the ocean surrounded by the highest mountains of the Oregon Coastal Range.

Climate
Foss has a borderline cool-summer Mediterranean and oceanic climate with cool, extremely amounts of rain in the cool season from October to April where at least a dozen inches of rain is seen each month, with only 2 inches of snowfall annually. Summers are barely warmer as temperatures are mild to occasionallywarm with August and July having no more than 1.2 inches of monthly precipitation. Because it lies at a low elevation surrounded by higher mountains near the ocean, heavy amounts of moisture get trapped in the region resulting in plentiful and heavy rainfall.
