What October is like in San Diego

October is clear, warm, and quiet. Highs sit near 74F (23C), the ocean is still fairly warm early in the month, and the summer crowds are gone. Now and then, dry Santa Ana winds blow in from the desert and bring a few hot days, and with them fire danger in the hills. Hotel rates drop to reasonable levels.

This month suits couples, retirees, and families with flexible schedules who want beach weather at fair prices. It is a great choice for a first visit. The only thing to watch is a Santa Ana heat spell, so keep an eye on the forecast and any fire advisories.

Make the most of October

What is especially good about San Diego this month.

01

Quiet warm beaches

Early October still has swimmable water and sunny days, and the sand at Coronado and Pacific Beach is far emptier than in summer.

02

Clear Santa Ana days

When the offshore winds blow, the air turns crisp and clear, and the views from Point Loma and Torrey Pines stretch a long way.

03

Good value hotels by the water

Rates at the beach fall after summer, so it is a good month to stay in La Jolla or Coronado.

What to pack for October

  • A swimsuit for early month beach days
  • A light jacket for cooler nights
  • Sunscreen and plenty of water for hot Santa Ana days
  • Comfortable shoes for trails and the zoo

Our timing tip

Come in the first half of the month for the warmest water, and check for Santa Ana wind or fire warnings before planning hikes.

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.
