Kelp forests, canyon shore dives, and classic wrecks on Southern California's doorstep
When to go
San Diego diving is year-round, but conditions change by season.
Best overall window
Warmest water, better chances for calm mornings and comfortable surface intervals.
Outside that window
Colder water and higher chance of storm swell. Shore entries can be hazardous on big surf days.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
