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