May Packing List for San Diego — What to Wear & Bring

Essentials

If you only pack a few things, pack these.

• Light cardigan or zip fleece for morningsEssential

  San Diego's May marine layer (June Gloom starting) keeps mornings overcast and 60–65°F until noon — a light cardigan or zip fleece handles the cool morning stretch before the layer burns off and afternoon temperatures reach 73°F.

• T-shirts and lightweight breathable topsEssential

  San Diego's May afternoons clear to 73°F and full sunshine once the marine layer lifts — breathable cotton or linen tops work for the warm afternoon outdoor time at Balboa Park, Pacific Beach, and La Jolla.

• Light jeans, shorts, or casual pantsEssential

  May's range in San Diego (61°F mornings, 73°F afternoons) means lighter bottoms work all day — shorts are comfortable in the afternoon while light jeans bridge the slightly cooler morning marine layer.

• Comfortable walking shoes or clean sneakersEssential

  May is prime season for San Diego's outdoor attractions — mild 73°F afternoons make Balboa Park, the Zoo, and Torrey Pines hikes ideal in cushioned walking shoes without summer heat.

• SunglassesEssential

  San Diego's May afternoons are increasingly bright as the dry season begins — once the marine layer burns off, UV is direct and strong, making sunglasses essential for outdoor Balboa Park time and beach visits.

• SPF 50 sunscreenEssential

  Southern California's May UV Index reaches 8–9 in San Diego on clear afternoons — once the June Gloom marine layer lifts, full-strength SPF 50 is appropriate for the intense afternoon sun exposure at outdoor venues.

• Light summer dress or skirtRecommended

  San Diego's May afternoons at 73°F are excellent for dresses — Balboa Park, the Gaslamp Quarter outdoor patios, and the beach communities are all comfortable in light dresses once the marine layer lifts by noon.

• Lightweight layer for coastal areasRecommended

  La Jolla Cove and Coronado Beach in May are 5–8°F cooler than inland San Diego — a lightweight jacket or overshirt handles the ocean breeze at waterfront locations even on warm afternoons.

Footwear

• Comfortable walking shoes or clean sneakersEssential

  May is prime season for San Diego's outdoor attractions — mild 73°F afternoons make Balboa Park, the Zoo, and Torrey Pines hikes ideal in cushioned walking shoes without summer heat.

• Sandals or flip-flops for beach areasRecommended

  San Diego's Pacific Beach, Ocean Beach, and Coronado are active in May — beach sandals or flip-flops handle the sand and waterfront boardwalk areas of these SoCal beach communities.

• Trail shoes for Torrey PinesOptional

  Torrey Pines State Reserve's coastal trail requires footwear with traction — May's mild temperatures and low precipitation make it the ideal month for the clifftop trail with ocean views.

Accessories

• SunglassesEssential

  San Diego's May afternoons are increasingly bright as the dry season begins — once the marine layer burns off, UV is direct and strong, making sunglasses essential for outdoor Balboa Park time and beach visits.

• SPF 50 sunscreenEssential

• Reusable water bottleRecommended

  San Diego's 73°F May afternoons with increasing outdoor activity make hydration important — a reusable bottle is practical for Balboa Park circuits and the Zoo's full outdoor trail.

• Wide-brim hatRecommended

  Balboa Park's open pathways and San Diego's May sun offer limited overhead shade once the marine layer clears — a wide-brim hat provides meaningful UV protection during midday outdoor walks.
