Essentials

If you only pack a few things, pack these.

Light jacket or denim jacketEssential
April mornings in San Diego start at 57°F — a light jacket handles the morning cool that burns off quickly as temperatures climb to 71°F, with just 3 rainy days making a heavy rain coat unnecessary.

San Diego's 71°F April afternoons are warm and pleasant — breathable cotton or linen tops are the right weight for afternoon outdoor time at Balboa Park, the Gaslamp Quarter, and coastal La Jolla.
Light jeans or casual trousersEssential
April's mild conditions in San Diego make light jeans the versatile everyday choice — appropriate for the beach-casual SoCal aesthetic at the Gaslamp Quarter, Coronado, and Balboa Park.
Comfortable walking shoes or sneakersEssential
April is one of San Diego's best months for outdoor exploration — mild 71°F conditions make full-day Balboa Park circuits and the San Diego Zoo visits comfortable in cushioned walking shoes.
SunglassesEssential

SPF 30–50 sunscreenEssential
April marks the start of meaningful UV exposure in San Diego — Southern California's UV Index climbs to 7–8 in April, and extended outdoor time at Balboa Park and the Zoo warrants consistent sunscreen application.
