March Packing List for San Diego — What to Wear & Bring
March is the last of San Diego's rainy season months — 6 precipitation days, 54°F mornings, and 68°F warm afternoons. Light layers and a waterproof jacket handle the variability as the city transitions from winter rain to spring sunshine.
Averages 54–68°F, ~6 days of rain
March is San Diego's final high-rain month at 6 precipitation days — a packable waterproof jacket handles the rainy stretches while being light enough for the pleasant 68°F afternoons at Balboa Park and the Gaslamp Quarter.
San Diego's March mornings start at 54°F — warmer than January's 49°F, which means a lighter mid-layer works well before the afternoon warms to 68°F at Balboa Park's sun-exposed paths.
March's 68°F San Diego afternoons are warm enough for t-shirts in the afternoon sun — breathable tops work as the base layer under a light sweater for the morning and as a standalone by noon.
San Diego's March mild conditions make light jeans the versatile everyday bottom — appropriate for the Gaslamp Quarter, Balboa Park, and casual beach-adjacent neighborhoods without being too warm for the pleasant afternoons.
March's 68°F San Diego afternoons on dry days are warm enough for light dresses — Balboa Park's gardens and outdoor museum plazas are pleasant in spring dresses when the rain clears.
March's 6 rainy days keep San Diego's Balboa Park paths and Gaslamp Quarter sidewalks intermittently wet — water-resistant sneakers handle the damp without the weight of winter boots in the mild conditions.
March is ideal for Balboa Park's full museum circuit in San Diego — mild 68°F temperatures without summer heat make long walking days pleasant in well-cushioned walking shoes.
San Diego's warm 68°F March afternoons between rain systems invite open-toe sandals — the Gaslamp Quarter's flat outdoor dining areas and dry sunny afternoons at Coronado Beach are comfortable in sandals.
March's 6 rainy days make an umbrella the most useful San Diego accessory for the month — Balboa Park and the Gaslamp Quarter lack overhead shelter during showers.
San Diego's March sunshine between rain systems is increasingly bright — the UV Index reaches 5–7 on clear days, and sunglasses protect eyes during the outdoor Balboa Park and La Jolla coastal walks that become more frequent as spring arrives.
Southern California's UV in March is already meaningful at San Diego's latitude — UV Index values of 6–7 are common on clear days, and extended Balboa Park outdoor time warrants sunscreen.
March coastal visits to La Jolla Cove and Coronado Beach are still 5–8°F cooler than inland San Diego — a light scarf handles the ocean breeze on waterfront walks during the 54°F mornings.
March's increasing warmth (68°F) and active outdoor use of Balboa Park and the Torrey Pines State Reserve make hydration more relevant than winter — a reusable bottle handles the multi-mile walking circuits.
March's final 6 rainy days in San Diego are worth a compact umbrella in the day bag — the wet season ends in April and the remaining showers come in brief systems that a compact umbrella handles efficiently.
March's variable San Diego weather — rain morning, sunny afternoon — means carrying peel-off layers and an umbrella benefits from a lightweight daypack for full-day Balboa Park and Zoo visits.
Local tips for San Diego in March
- 1.March is the last month of San Diego's rainy season — rain becomes much rarer from April onward, so if outdoor activities like Torrey Pines hiking or Coronado Beach days were rained out, spring is coming fast.
- 2.The San Diego Zoo's Safari Park in Escondido is a March highlight — cooler 68°F temperatures without summer heat make full-day visits comfortable, and spring greenery from the rainy season makes the landscape particularly beautiful.
- 3.San Diego's March spring break crowds begin arriving mid-month — Gaslamp Quarter, La Jolla, and Pacific Beach get significantly more active; plan early morning visits to popular spots to avoid the crowds that afternoon sun brings.
