There's no actual dividing line between Northern and Southern California, but the Central Coast area (Santa Cruz, Monterey, Santa Maria) would be what most Californians would consider the dividing line.

On a related note, the "divide" or rivalry between SF and LA pales compared to the real (social) divide along the crest of the Coast Ranges. "Coastal California" and "Inland California" are much more distinct from each other, politically, socially, and economically...
