Southern California, Geographic region in California, US.
This geographic region spreads across ten counties and includes Pacific coastlines, valleys, deserts, and mountain ranges. The terrain connects urban centers with rural areas and open wilderness, often shifting between sea level and elevations above 10,000 feet (3,000 meters).
During the 20th century, the population grew rapidly through the construction of water supply systems and road networks, turning farmland into dense metropolitan areas. The film industry developed from the 1910s onward and shaped the economic direction for decades.
The year-round climate shapes daily habits, with people often dining outdoors, exercising in parks, or spending afternoons at the beach. In many neighborhoods, surfboards on car racks, yoga mats, and casual clothing are part of everyday street scenes.
The coast enjoys mild weather year-round, while inland and desert areas experience high summer heat and cooler winters. The best times to visit depend on your chosen area, with spring and fall comfortable for nearly all zones.
You can drive from the ocean to mountains and onward to desert in a single day without leaving the area. This proximity of contrasting environments allows residents and travelers to experience completely different landscapes within a few hours.
