Oceanside, California is a popular destination for relocation because of affordability, beautiful beaches, attractive Harbor and near perfect weather. This also makes Oceanside a popular alternative to San Diego, California relocation. Oceanside is located just 35 miles north of San Diego and 90 miles south of Los Angeles – far enough away to still have small town appeal, but close enough to provide access to urban amenities. Oceanside is the perfect Southern California relocation paradise that can serve the entire family.
