High season for tourists (July-August)

Summer is the most popular season for tourists coming to San Diego. Although fog and clouds can still float above July, the summer season brings public holidays and lasts until the weekend of Labour Day, when people go back to school and work.

The summer season also attracts a number of people living in desert states to escape the heat, as some residents of Phoenix and Las Vegas have a second home in the area. They may not be tourists, but they will compete for the same tables in restaurants, so plan and book in advance.

Shoulder seasons (March-June and September-November)

Spring, early summer and autumn are shoulder parts. The number of tourists is lower than in summer: Work and school determine the schedule, but San Diego is still popular because of its mild climate and relaxed atmosphere by the sea.

The tourist season accelerates when the weather gets dry and warm at the end of March, but the fog in May and June reduces the number of tourists in late summer. The number of tourists has been falling since Labour Day, but only when it is wetter and cooler until the end of November.

Low season (December to February)

Winter is the slowest tourist season in San Diego. As night temperatures in the sheltered area drop and the rainy part of the year begins, the tourist season becomes increasingly closed.

Surprisingly, the daily highs in January and February are always above 17°F and it only rains one or two days a week. So if you want to take advantage of the low season, avoid crowds and spend a lot of money on hotels and flights, this might be a good time to come to San Diego.
