Bring SPF 50+ sunscreen (266 sunny days per year), polarized sunglasses, sandals plus grippy walking shoes for Torrey Pines, and a swimsuit year-round. A passport or passport card is required for a Tijuana day trip across the San Ysidro border.

San Diego enjoys some of the best weather in the United States, with mild temperatures, low humidity, and sunshine nearly year-round. The city is built around outdoor living, from the beaches of La Jolla and Coronado to the trails of Torrey Pines and the world-famous San Diego Zoo. The vibe is relaxed and casual, so you can leave the formal attire at home.

The city has two loose seasons: a warm, dry summer from May through October and a mild winter from November through April with occasional rain. Morning marine layer fog is common, especially in May and June (locals call it "May Gray" and "June Gloom"), so packing a light layer for mornings is always a good idea even in summer.

San Diego sits just 20 miles from the Mexican border, making Tijuana day trips a popular option. If you plan to cross, bring your passport. Whether you are surfing in Pacific Beach, exploring Balboa Park, or eating your way through the Gaslamp Quarter, San Diego rewards travelers who pack light and dress for comfort.

Temperature: 65-80°F°F APR 26 Warm and dry with plenty of sunshine. Humidity stays low, and rain is extremely rare. Morning marine layer fog is common in May and June, burning off by midday. July through October is the warmest stretch, with highs regularly reaching 75 to 80°F. Ocean water temperatures range from 65 to 72°F, comfortable for swimming and surfing.

Packing Tips for San Diego, California

  1. 1 San Diego is one of the most casual cities in the US. Shorts, sandals, and a t-shirt are appropriate almost everywhere, including most restaurants.
  2. 2 Morning marine layer fog ("May Gray" and "June Gloom") can keep temperatures cool until midday. Always bring a light layer for mornings, even in summer.
  3. 3 If you plan a day trip to Tijuana, Mexico, bring your passport or passport card. You will need it to re-enter the United States at the San Ysidro border crossing.
  4. 4 Bring a reusable water bottle. San Diego tap water is safe to drink, and staying hydrated is important in the dry climate.
  5. 5 Wear your bulkiest shoes on the plane to save luggage space. Sneakers or hiking shoes work best for this.
  6. 6 Pack layers rather than heavy clothing. Temperatures can swing 15 to 20 degrees between morning fog and afternoon sunshine.
  7. 7 Sunscreen is essential year-round. San Diego averages 266 sunny days per year, and UV exposure adds up quickly even on overcast mornings.
  8. 8 A lightweight daypack is useful for beach trips, zoo visits, and hikes at Torrey Pines or Cabrillo National Monument.

Frequently asked questions

Do I need a passport to visit San Diego?
You do not need a passport to visit San Diego itself, since it is a US city. However, if you want to take a popular day trip across the border to Tijuana, Mexico, you will need a valid US passport or passport card to re-enter the United States at the San Ysidro Port of Entry. The crossing is about 20 minutes by trolley from downtown San Diego.
What is May Gray and June Gloom?
May Gray and June Gloom refer to a thick marine layer of fog and low clouds that rolls in from the Pacific Ocean during late spring and early summer. Mornings are overcast and cool, but the fog usually burns off by midday, giving way to sunshine and warm temperatures. Pack a light jacket or hoodie for mornings during these months, even though afternoon highs reach the mid-70s.
What should I wear to dinner in the Gaslamp Quarter?
San Diego is very casual. Most Gaslamp Quarter restaurants accept clean, put-together casual attire: a nice t-shirt or button-up, jeans or chinos, and clean sneakers or sandals. Only a handful of fine dining spots have a stricter dress code. You do not need to pack formal clothing for a San Diego trip.
Is it warm enough to swim in the ocean year-round?
Summer ocean temperatures range from 65 to 72°F, which is comfortable for most swimmers. Winter temperatures drop to 57 to 63°F, which feels cold without a wetsuit. Many surfers wear wetsuits year-round in San Diego. If you are sensitive to cold water, plan beach swimming for July through October when the water is warmest.
How much rain does San Diego get in winter?
San Diego averages about 10 inches of rain per year, nearly all of it falling between November and March. Rain typically comes in short bursts lasting a few hours rather than all-day downpours. Most winter days are still sunny and mild. A packable rain jacket and a compact umbrella are all you need to stay prepared.
Do I need hiking boots for Torrey Pines?
Sturdy sneakers or trail runners work well for Torrey Pines State Natural Reserve in dry conditions. The trails are well-maintained with some sandy and uneven sections. After rain, trails can be muddy and slippery, so water-resistant hiking shoes with good traction are recommended. The reserve does not allow bikes, strollers, or food on the trails.
Should I rent a car in San Diego?
A rental car makes it much easier to explore San Diego. The city is spread out, and attractions like Torrey Pines, La Jolla, Coronado, and the border crossing are scattered across a large area. Public transit covers downtown and the airport well, but reaching beaches and parks outside the core often requires a car or rideshare. Parking is generally easy and affordable outside of downtown.
What is the best time of year to visit San Diego?
September and October offer the best combination of warm weather, minimal fog, warm ocean water, and smaller crowds. Summer (July and August) is peak tourist season with higher hotel prices. Winter (December through February) is mild and uncrowded, ideal for whale watching, hiking, and exploring the city without the summer rush. San Diego is pleasant to visit in any month.
