eptember handed off a changed ocean. Hurricane Marie delivered the summer's biggest swell and rearranged the Laguna coast, and then the water flipped cold and the fall pattern set in. October is the payoff month. In most years it is the single clearest stretch on the California calendar - the bloom is gone, the crowds have thinned, the swell windows get longer, and the first Santa Ana winds glass off the ocean. On top of that, lobster season is open and the groundfish deep zo

September 2026 California Diving Wrap-Up: Marie's Swell, the Cold Flip, and the Fall Clarity Payoff

Orange County has a lifetime of diving packed into a relatively short stretch of coast, and most of the best of it is concentrated around Laguna Beach. This is our overview - a north-to-south tour of the popular sites, plus a few standouts beyond the county line - to help you decide where to get wet. For most of these spots there are detailed guides out there with maps, parking, site features, and hazards; think of this as the big-picture map that points you in the right dire

California's spiny lobster season opens in early October - and for a lot of us that's the highlight of the fall. With the opener now about two weeks out - it opens Friday, October 2 at 6 p.m. - and the water finally cooling into prime bug-diving range after the Marie swell, now is the time to get your gear, your paperwork, and your spots sorted. Here's the checklist.

If you dropped into Shaw's Cove this week and thought the bottom looked... different - lower, rockier, more reef than you remembered - you're not losing your mind. The big south swell that ran through over Labor Day did what big swells do: it grabbed the sand and moved it. Here's what happened, why it happens, and what it means the next time you gear up.

Over Labor Day weekend, the leftovers of Hurricane Marie threw a giant south swell at Southern California, and the whole coast felt it. The storm itself never came close - it stayed 700-plus miles to the south and west - but the long-period energy it fired off put High Surf and Coastal Flood advisories on the map through Tuesday, and set off a chain reaction that touched water temperature, visibility, the shape of our favorite coves, and even what showed up on the reef.

The thermometer just dropped, and if you dive San Diego you should be paying attention - because a cool-down like the one we just had is exactly the kind of switch that wakes up white seabass. After a summer of warm, lazy water, the ghosts of the kelp are back on the menu. Here's how to be ready.

The swell that worked Southern California over the holiday weekend - Saturday through today, Monday, September 7 - was a strong south to south-southwest swell thrown off by Hurricane Marie. What made it worth writing about was not the size so much as how directional it was. Some beaches got hammered while a cove a few hundred yards away sat almost calm. That is the whole story of this swell, and it is a good lesson in how to read a south swell as a diver.
