Founded in 1876, Occidental was a stop on the North Pacific Coast Railroad connecting Cazadero to the Sausalito ferry. In return for donating right-of-way to the railroad, a local landowner named "Dutch Bill" Howards received a lifetime railway pass, and the station was named after him.
The railway caused a rapid expansion of the timber industry, and by 1877 there were six sawmills in the Occidental area. Trains also brought vacationers from San Francisco.
The cooperative National Weather Service station reports that Occidental has cool, wet winters and warm, dry summers.

Culture and commerce 
Occidental is unique for its high concentration of visionaries and famous artists during recent history, and was the hub of community-centered social movements in the late 1960s and early 1970s, giving rise to nearby communes such as Morningstar, Wheeler Ranch, and Star Mountain.
There was a point in the early 1990s when the town was also a center of the "neo-hippie" movement in Sonoma County, but high property prices and other economic pressures have since driven out the young families that fed this movement.
For many years Occidental has been known for its Italian restaurants, which serve generous family-style dinners for a fixed price (following the European custom).(??) The two Italian restaurants today are the Union Hotel (founded in 1879) at 3703 Main Street and Negri's at 3700 Bohemian Highway. More recently, the large number of craft breweries and wineries in the area have made Barley and Hops Tavern and Sonoma Fine Wine store in downtown Occidental local and tourist destinations.
The tool-belt manufacturing company, Occidental Leather started in an Occidental barn and later moved to downtown Occidental.
