What August is like in San Diego

August is the warmest month of the year, with highs near 77F (25C), clear skies, and the ocean close to its warmest. Evenings stay pleasant on the coast, while inland valleys can get hot. It is also one of the busiest and priciest months: beaches fill by late morning, parking is hard, and hotels near the water book up early.

This month suits families who want swimming, surfing lessons, and long beach days, and who can plan ahead. It is less fun for travelers on a budget or anyone hoping for quiet. The same warm water and sun continue into September with far fewer people.

Make the most of August

What is especially good about San Diego this month.

01

Warm water for swimming

The Pacific is close to its warmest, so kids can actually stay in the water. La Jolla Shores is calm and good for first-time swimmers and snorkelers.

02

Summer racing at Del Mar

The Del Mar racing season runs all month, with ocean breezes and a relaxed day at the track.

03

Long evenings on the bay

Late sunsets make for easy evenings on Shelter Island, at Seaport Village, or on a sunset harbor cruise.

What to pack for August

  • Reef-safe sunscreen and a rash guard for kids
  • A snorkel and mask for La Jolla Shores
  • Sandals and water shoes
  • A light layer for breezy evenings

Our timing tip

Get to La Jolla Cove and Torrey Pines before 9am, since parking is usually full by late morning in August.

Beat the crowds

  • Avoid Comic-Con week downtown unless you are going. Stay in La Jolla or Coronado if dates overlap.
  • Hit La Jolla Cove and Torrey Pines early in the morning. Parking fills fast by late morning in summer.
  • Visit the zoo on a weekday outside school holidays.
  • Choose September and October for summer weather without summer prices.

Know before you go

  • The city runs fully year-round. Some Balboa Park museums close one weekday each week.
  • Beach water quality advisories can close stretches of shoreline after rain, especially near the Tijuana River in the South Bay. Check before swimming.
  • Santa Ana wind events in fall can bring heat and fire danger to the region.
