🛡️ Safety
San Diego
San Diego is one of the safer large cities in the US for visitors. The main tourist areas — Gaslamp Quarter, Balboa Park, La Jolla, Coronado, and the beaches — are generally safe and well-policed. The East Village and parts of downtown near the trolley station have some street homelessness and petty crime, but serious violent crime targeting tourists is rare. Exercise normal urban precautions.
Washington, D.C.
Tourist areas of DC — the National Mall, Capitol Hill, Downtown, Georgetown, Dupont Circle, and Foggy Bottom — are generally safe during the day and well into the evening. Like any major US city, DC has neighborhoods with higher crime, mostly in parts of Southeast and Northeast that tourists rarely visit. Petty theft, car break-ins, and occasional phone snatching are the main concerns.
⭐ Ratings
🌤️ Weather
San Diego
San Diego has the best year-round climate of any major city in the continental United States — a Mediterranean climate with warm, dry summers and mild, occasionally rainy winters. Average temperatures stay between 57°F and 77°F all year. The main quirk is "May Gray" and "June Gloom" — a marine layer of coastal fog that rolls in from the Pacific each morning, usually burning off by noon but sometimes persisting all day along the beach.
Washington, D.C.
Washington, DC has a humid subtropical climate with four distinct seasons. Summers are famously hot and sticky (the city was built on reclaimed swampland), while winters are cold but rarely extreme. Spring and fall are glorious and are the best times to visit.
🚇 Getting Around
San Diego
San Diego is primarily a car-dependent city, though downtown, the Gaslamp Quarter, and Balboa Park are very walkable. The San Diego Trolley connects downtown with Mission Valley, Old Town, and the Mexican border. Getting to La Jolla, the beaches, and Coronado is most convenient by car or ride-hail. The Coaster commuter rail connects downtown to North County beaches.
Walkability: Downtown San Diego and the Gaslamp Quarter are highly walkable. Balboa Park, Little Italy, and the Embarcadero are all connected by foot. However, San Diego is a sprawling metro — getting between neighborhoods like La Jolla, Mission Beach, and Old Town requires wheels or a ride.
Washington, D.C.
DC has an excellent public transit system run by WMATA (Washington Metropolitan Area Transit Authority). The Metro (subway) and Metrobus cover the city and much of the Maryland and Virginia suburbs. A SmarTrip card (or contactless phone tap) works across all Metro, bus, and Capital Bikeshare. Driving downtown is frustrating and parking is very expensive — transit or walking is the way to go.
Walkability: Central DC is one of the most walkable cities in the US, with wide sidewalks, a clear street grid, and short blocks. The National Mall itself is longer than it looks on maps (roughly 3 km end to end), so plan accordingly. Georgetown and Capitol Hill are especially pleasant on foot, though some DC hills can be steep.
