The cheapest month to fly to San Diego is usually January.

After the busy holiday time, not as many people want to fly. Airlines lower their prices to fill seats that would be empty. Early February is a good time to find low-priced tickets, too. During this time, you can often get cheap flights to San Diego at a much lower price than in the summer months.

Traveling in January lets you enjoy mild weather, with the temperature around 65°F or 18°C. There are fewer people at popular spots like Balboa Park, La Jolla Cove, and Mission Beach. You can also get lower prices on hotels and car rentals at this time.

To save even more money, try booking your flight to San Diego in the middle of the week. You can use fare alerts to get good prices. Look at airports close by as well. A tool like Booking Trolley can help you compare what is there and get the best deal.
