What April is like in San Diego

April is green, comfortable, and easy. Highs reach about 68F (20C), rain is rare, and most days are sunny, with a little morning haze on the coast later in the month. Crowds are moderate once spring break ends, and prices sit in the middle of the year's range. The ocean is still cool, but walking the beaches is lovely.

This month suits families, walkers, and first-time visitors who want to see the zoo, Balboa Park, and the coast in pleasant weather. It is not the month for serious swimming or snorkeling. If that is your priority, September brings the warmest water of the year.

Make the most of April

What is especially good about San Diego this month.

01

Whales heading north

Gray whales are still passing Point Loma on their way back north, often with calves. Shore watching from Cabrillo is worth a clear morning.

02

Balboa Park gardens in bloom

Spring is a good time to wander the park's gardens between museum visits. The weather is ideal for a full day outdoors.

03

The Safari Park in comfort

The Safari Park in Escondido gets hot in summer, but April days are mild. It is a great time for the open-range habitats.

What to pack for April

  • A light sweater for mornings and evenings
  • Good walking shoes for Balboa Park
  • Sunglasses and a sun hat
  • A light windbreaker for the coast

Our timing tip

Go in the second half of the month, after most spring breaks end, for the same weather with fewer families at the zoo.

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.
