If you're going to San Diego in June, you'll have lots of daylight hours to explore the city's attractions. It's not likely to rain on your vacation and temperatures on the average are just right.

June can be a good time to visit San Diego as long as you understand that it's just as likely to be overcast as it is to be sunny. And if you don't mind being in crowds at some of the most popular spots.

San Diego Weather in June

Early summer isn't the sunniest time in San Diego. In fact, the month has the least clear skies during the year because of coastal fog. But you'll still get the sun more than half the time. With the rainy season over, there's little chance of precipitation. Evening fog comes in suddenly and can feel unusually cold.

  • Average High Temperature: 71 F (22 C)
  • Average Low Temperature: 62 F (17 C)
  • Water Temperature: 65 F (18 C)
  • Rain & Clouds Index: 0.07 in (0.2 cm)
  • Sunshine: 58 percent
  • Daylight: 15 hours from sunrise to sunset, mid-month

If you want to compare these weather conditions to what San Diego is like the rest of the year, you can find that all in one place in the guide to ​typical San Diego weather.

The weather information above is best used as a general idea of what things may be like. Averages are helpful for planning, but don't count on your trip being "average." Check the San Diego weather forecast before you leave home.

What to Pack

Pack a mid-weight jacket, especially for the evening near the water. Bring short-sleeved shirts and lightweight pants, with a sweater for layering, and you may want shorts on the warmest days.

If you plan to be near the ocean in the evening, it will feel colder than you might think and you'll be glad you took an extra layer or two.

If you’re going to the beach, you may want to wiggle those ten fine toes in the sand. But getting that sand off your feet and out of everything else you own can be hard. To make it easier, pack a little bit of baby powder or cornstarch to put into your day pack. Sprinkle it on your skin and the sand will brush off much easier.

  • March through August is time for a uniquely California event. During the annual grunion run, thousands of tiny, silvery fish mate by the light of the full moon (or the new one). See the schedule here. The best San Diego beaches to see the show are La Jolla Shores, Pacific Beach between Tourmaline Park and Lifeguard Tower 20, Mission Beach between Lifeguard Towers 19 and 10, Ocean Beach between Mission Bay Channel and the Ocean Beach Pier and on Coronado between the Hotel del Coronado and Dog Beach.
  •  The Padres' pretty downtown baseball stadium is a great place to watch a game. If you don't like them, go anyway and root for their opponents.
  • Between July and September, leopard sharks gather just off the La Jolla coast of La Jolla. These beautiful spotted creatures are timid and docile. You see them and wade alongside them at La Jolla Shores. The Birch Aquarium at Scripps hosts leopard shark snorkeling adventures and La Jolla outfitters like Hike Bike Kayak and Everyday California offer leopard shark snorkeling tours.
