San Diego is located on the west coast of the U.S.A, in the south of the state of California. It is bordered by the Mexican border to the south, Orange County to the north, the Pacific Ocean to the west and the Cuyamaca and Laguna mountains to the east. The San Diego river crosses the city, its downtown built between the Point Loma and Coronado peninsulas that seem to shelter it, and its suburbs in the canyons and plateaus that form naturally mark out the various districts. The region enjoys a semi-arid oceanic climate, tempered by the coastal winds of the Pacific, and thus offers hot, dry summers cooled by the ocean breeze, and mild, sunny winters.
