There is NO weather better than sunny San Diego year round. We stayed at Mission Beach at an Air BnB right between Mission bay and the Pacific ocean! Walkable distance to either, the location was fantastic. The Boardwalk, Seaworld, and Zoo were all so close so we had to visit them all! If it weren't for the high living cost, I'd consider living in San Diego just becacuse of the perfect weather. Well, I'll just visit it for the meantime.
You will see San Diego Zoo, Seaworld, the Boardwalk, Mission Beach, City cruise, Mission Bay, Birch Aquarium.
