What to expect
Despite visibility and water temperature being on the lower scale when compared to tropical destinations, snorkeling in San Diego packs the whole punch of cold-water snorkeling.
When snorkeling in San Diego, you'll have the chance to encounter:
- Sea Lions: a day trip to Coronado Islands' local rookery
- Sharks: leopard sharks are guaranteed in the summer months
- Rays: in La Jolla and Mission Bay, common in the summer
- Sea Turtles: although rare, they inhabit La Jolla year round

Snorkeling conditions
Visibility changes hourly, from site to site. These are San Diego snorkeling averages:
- Average: 15 to 30 ft
- Best: 50 ft+ locally & 100 ft+ at the Coronado Islands (fall & winter)
- Worst: 5 ft (usually during algae blooms)*
Water temperatures vary with the seasons and range between:
- May - October: 62° to 70°F
- November - April: 58° to 61°F
✨ LOCAL TIP: Water conditions here change hourly. We keep a running Conditions Report spreadsheet to better forecast future visibility for our boat charters.

Coronado Islands, a day trip to Mexico away, tend to have 1 to 3°F higher surface and bottom temperatures. Every bit counts!
San Diego waters are nutrient-rich, which helps kelp forests and cold-water species like sea lions and some shark species to flourish.
Gear requirements
If you plan to snorkel in San Diego, exposure protection is a must.
We recommend wearing a full 5mm wetsuit during the summer and a full 7mm wetsuit and a hood in the winter. If you don't have your own gear, keep on reading for some San Diego snorkel gear rental recommendations.
Snorkeling conditions here change hourly. We keep a running Conditions Report spreadsheet to better forecast future visibility for our boat charters.
✨ GEAR TIP: When snorkeling off the beach, keep your mask around your neck (not your forehead!) and your fins securely in your hands. The waves may look unassuming, but gear is lost in the surf all the time.
San Diego marine life
San Diego’s rugged topography and its Marine Protected Areas create the perfect home for creatures unique to the Pacific Coast.
Although you can’t expect to see every creature on your first snorkel tour, there’s a good chance of finding kelp bass, sheephead, garibaldi, and blacksmiths almost every time you get in the water!
For those either lucky enough or patient enough, you may find giant sea bass, horn sharks, green sea turtles, sevengill sharks, sea lions or our curious harbor seals.

Accessing snorkeling sites
All San Diego snorkeling spots are public access. Some are easy to access, some require a strenuous workout, and some are only accessible by boat. See our next section for details on the main snorkeling spots in San Diego.
If you've never snorkeled before, we highly recommend joining a snorkel charter or a guided snorkel tour so you can easily find entry points and species of interest.
We are the only commercial boat running snorkel charters in San Diego and to the Coronado Islands.
✨ LOCAL TIP: The early bird gets the worm! Get into the water and start snorkeling early in the morning when the reef is coming to life and activity is high.
