Given this paragraph, can you tell me why Santa Barbara is referred to as The American Riviera?

Santa Barbara is a coastal city in Santa Barbara County, California, of which it is also the county seat. Situated on a south-facing section of coastline, the longest such section on the West Coast of the United States, the city lies between the steeply rising Santa Ynez Mountains and the Pacific Ocean. Santa Barbara's climate is often described as Mediterranean, and the city has been dubbed "The American Riviera".

Santa Barbara is referred to as The American Riviera because of it's temperate climate and south-facing orientation to the coastline.
