What's actually worth your time in San Diego
Balboa Park is 1,200 acres of Spanish Revival buildings from the 1915 exposition, seventeen museums and free gardens, and you can spend a day without paying anything. Cabrillo National Monument on Point Loma costs twenty dollars a vehicle for seven days and is worth timing to low tide for the tidepools. La Jolla Cove's sea lions are free, loud and pungent.
When the weather turns in San Diego
San Diego gets around ten inches a year, almost all between December and March, so a wet day is genuinely unusual. Balboa Park's museum cluster is the obvious plan, the Midway's hangar deck stays dry, the Fleet Science Center runs dome films, and Liberty Station's Public Market in the old naval training centre is entirely under cover.
What first-timers get wrong in San Diego
May Gray and June Gloom are real: the marine layer sits over the coast all morning through late spring and burns off around noon, and visitors book June beach weeks expecting sun. Balboa Park parking is free but full by ten on weekends. Alcohol is banned on city beaches. The Blue Line trolley runs to the border crossing at San Ysidro.
San Diego's museums, and which one to pick
Free entirely, the Timken in Balboa Park holds European old masters and a room of Russian icons, which makes it the sharpest hour in the city; the San Diego Museum of Art beside it charges. The Museum of Us occupies the 1915 California Tower, with the tower climb ticketed separately. USS Midway on Navy Pier includes the audio guide and the island tour.
