These statistics represent 30-year averages (1995-2024) from San Diego International Airport, located in the coastal zone. The Comfort Score (0-100) combines temperature and humidity. San Diego's marine layer keeps summers mild compared to inland areas—temperatures rarely exceed 80°F near the coast, making it one of America's most pleasant climates year-round.
San Diego's mild temperatures allow flexible scheduling. For beach weddings, late afternoon (4-5 PM) captures the Pacific sunset. Morning ceremonies (10 AM) often feature clear skies before afternoon marine layer clouds—though these clouds rarely bring rain.
San Diego experiences marine layer clouds in May-June that typically burn off by noon. This isn't rain—just overcast mornings. Plan afternoon or evening events during these months, or embrace the moody coastal atmosphere. July-September are typically clearer.
Coastal venues (La Jolla, Coronado) stay 10-15°F cooler than inland locations (Temecula, Escondido). For wine country venues in Temecula, check inland forecasts separately—summer can reach 90°F+. Our data is for the coastal zone near the airport.
San Diego offers spectacular sunset photography year-round, with the Pacific creating dramatic backdrops. In summer, sunset is around 8 PM; in winter, around 5 PM. The Torrey Pines cliffs, Balboa Park gardens, and Hotel del Coronado are iconic photo locations.
