Insider timing tips
- •San Diego experiences 'June Gloom' and 'May Gray,' where morning fog can linger into the afternoon, particularly along the coast.
- •While summer offers the warmest ocean temperatures, it also brings peak crowds and prices, making the shoulder months of April-May and September-October ideal for a balance.
- •The dry season typically runs from April to October, with the wettest months being January and February, though rainfall is generally moderate.
- •Even in winter, daytime temperatures remain mild, making outdoor activities like hiking and visiting Balboa Park enjoyable year-round.
- •The proximity to the Pacific Ocean significantly moderates San Diego's climate, preventing extreme heat or cold compared to inland California cities.
