Where to swim with leopard sharks in La Jolla (and when they show up)
Every summer and fall, hundreds of harmless leopard sharks gather in waist-deep water off La Jolla Shores near the Marine Room. Go June to early December, peak August–September, on a calm morning at low tide.

The short version
- Leopard sharks gather in the warm, shallow water off La Jolla Shores from roughly June to early December, peaking in August and September.
- Scripps researcher Andy Nosal found about 97% of them are pregnant females, likely warming up to speed their pregnancies.
- They're harmless to people: small mouths built for crabs, clams and worms.
- Look for them in waist-deep water near the Marine Room, at the south end of the beach, on calm mornings around low tide.
- It's a protected marine reserve: look, don't touch or chase.
Yes, you can wade into the Pacific in La Jolla and have sharks swim past your shins, and it's one of the safest wildlife encounters in California. Every summer, leopard sharks (spotted, 3 to 5 feet long, very shy) pack into the shallow, sun-warmed water at the south end of La Jolla Shores.

Why they're here
Scripps Institution of Oceanography researcher Andy Nosal's work found roughly 97% of the sharks are pregnant females. The leading idea is that they bask in warm, calm water to speed up their pregnancies, then leave as the water cools in late fall (KPBS).
How to see them
- 01
Pick a calm morning
Early morning usually brings flat water and better visibility, before wind and crowds stir up the sand.
- 02
Aim for low tide
Lower tides put the shark zone in waist-deep water, so you can see them just by wading.
- 03
Walk south toward the Marine Room
Enter at Kellogg Park and head south along the beach. The sharks hang just offshore of the restaurant.
- 04
Float, don't chase
Lie still with a mask and snorkel and they'll swim by. Splashing scatters them.
- Water temperature: about 68–72°F in summer; a thin wetsuit helps in fall.
- Rules: this is part of a protected marine reserve. Don't touch, feed or harass the sharks.
- Stingrays: they share the sandy bottom. Shuffle your feet as you walk.
- Guided option: local snorkel shops run shark tours with gear in summer.
