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.
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.
What to eat in San Diego
Two dishes were invented or perfected here. The Baja-style fish taco, battered and fried with cabbage and crema, came north from Ensenada and is best at the walk-up counters like Oscar's. The California burrito, carne asada with french fries inside, exists nowhere in Mexico and is entirely a San Diego creation. Convoy Street is the Asian dining corridor; Little Italy runs a large Saturday mercato.
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.
What things cost in San Diego
MTS charges $2.50 a ride and caps at a $6 day pass, paid by PRONTO card, app or contactless, with under-eighteens free. Cabrillo is twenty dollars a vehicle for a week. The zoo is around seventy-two dollars for adults and is the day's big spend. Timken admission is free. A fish taco runs four to six dollars.
