Although the sun is known to always shine over the Golden State, the best times recommended to visit San Diego are from March to May, and from September to October, when you can expect great weather and moderate rates. Watch out for the cloudy skies in May. Summertime is always recommended for hot temperatures and countless events taking place around the city. However, hotel fares are more expensive. Be aware of the gray skies in June. For the best hotel rates, the winter months are the best option. Even though the winter in San Diego is far from freezing, expect rain showers and water a tad too cold for swimming.

The trolleys operate from about 5am to midnight, seven days a week.

The PRONTO card is San Diego's transportation card, allowing easy access to both trolleys and buses.
