Today, the email went out to 1,107 registered swimmers: the La Jolla Cove Swim, set for Sunday, September 13, is off. Not postponed by a few hours for fog, which happens most years. Canceled outright, two days before race day, because there was nowhere safe left to put people in the water.
If you've lived in La Jolla for any stretch of Septembers, you know this race as background noise to the season, the one where a few thousand people crowd Scripps Park at dawn and the Cove briefly belongs to swimmers instead of paddleboarders. What most residents haven't connected yet is that this cancellation is the third time in 2026 that this exact stretch of coastline, from the Cove down through Bird Rock, has forced someone to change plans because the shoreline itself moved. Read on their own, each story sounds like a local curiosity. Read together, they describe one coastline behaving differently this year than it has in recent memory.
What Actually Happened at the Cove
Race director Aaron Brennan has run the event for four years, and he did not make this call lightly. A site inspection on September 8 confirmed what the tide charts had been threatening: high tides combined with what Brennan called significant beach erosion left almost nothing to work with.
"There is effectively no rock-free beach available at race time for you to safely enter and exit the water."
San Diego lifeguards agreed the conditions wouldn't support a safe start and finish, and that settled it. The race that debuted in 1916 alongside San Diego's Panama-California Exposition, and that is now the second-oldest open-water swim in the country, will sit out its own 110th year. Registered swimmers can roll their entry fee to 2027 or send it to the Prevent Drowning Foundation of San Diego County, the nonprofit the Kiwanis Club of La Jolla has funneled roughly $100,000 toward over the past three years through this event alone.
The frustrating part, for Brennan and for the swimmers who signed up, is that this was shaping up to be the biggest field yet. More than 1,100 entrants had registered, about 200 more than last year and nearly double 2023's turnout. The race has never been more popular. The beach underneath it has never given the organizers less room to work with. That contrast is the story.
Three Signals From the Same Stretch of Coast
None of this happened in isolation. In 2026 alone, three separate situations along this stretch of La Jolla coastline between the Cove and Bird Rock have each, independently, forced someone to rethink how they use it.
| Location | What's happening | Timeline | Current status |
|---|---|---|---|
| La Jolla Cove | Race canceled after high tides and erosion left no safe entry point | Called off September 9, 2026, for the September 13 race | Deferred to 2027 |
| Point La Jolla | Growing sea lion colony has triggered debate over a pupping-season beach closure | Point La Jolla closed to people since September 2023; new closure debate through August 2026 | Advisory board vote taken, nothing enacted |
| Bird Rock (Calumet Avenue) | Crumbling bluff forced a homeowner to demolish part of a back patio; seawall pending city approval | Concerns raised over a year ago; new citywide setback rules took effect July 1, 2026 | Awaiting permits |
None of these three are the same phenomenon technically. A shrinking beach at high tide, a sea lion colony testing the limits of a 2023 closure, and a bluff losing ground under a Bird Rock home are different physical processes. But they're happening on the same coastline, in the same calendar year, and each one has already changed how a resident interacts with the water's edge, whether that resident is a swimmer, a dog walker on the Scripps Park lawn, or someone who owns a house on Calumet Avenue.
The Sea Lions Got Here First
The Cove's sea lion situation has been building since the city permanently closed Point La Jolla and Boomer Beach to people in September 2023 under a seven-year Coastal Commission permit. That closure was meant to give the colony a place to haul out undisturbed, and it worked almost too well. Since June 2026, 56 sea lion births have been recorded near the Cove, alongside eight pup deaths, and the growing crowding has produced friction: an 18-year-old pleaded guilty in August 2026 after kicking one of the animals.
At the Coastal Commission's August 14 meeting, commissioner Matt O'Malley said a partial closure of the Cove itself was, in his view, the only way to handle it. Ten days later, the La Jolla Parks & Beaches advisory board voted to ask the city to consider closing the Cove's west staircase during pupping season while keeping the east staircase open for water access. The City Council president has publicly opposed closing the Cove, and as of the most recent check nothing has been enacted, voted into law, or scheduled. It's an open question, not a settled one, but it's a question that exists specifically because the coastline's balance between people and wildlife has shifted noticeably this year.
A Mile South, the Bluffs Are Making the Same Point
Down in Bird Rock, the Calumet Avenue bluff has been a slow-motion concern for more than a year, but this spring the concern turned physical. Crews demolished part of a back patio on one home because erosion beneath it left no other option, and the homeowner is hoping to be folded into a seawall project already planned next door. A few doors down, resident Greg Daunoras told a local news crew he expects to need his own protective measures within a year or two or three, calling erosion "a real issue" that keeps getting worse rather than stabilizing.
Whatever gets built there will now have to clear a higher bar than it would have just two months ago. San Diego's City Council adopted its first Coastal Resilience Master Plan in September 2025, and as of July 1, 2026, updated bluff setback rules took effect for Pacific Beach, La Jolla, and Bird Rock, incorporating new 75-year erosion projections. The practical result pushed required setbacks from roughly 53 to 55 feet up to 63 to 64 feet, a jump of nine to ten feet, for new development along these bluffs. That's not a number most residents will ever need to calculate themselves, but it's a useful gauge of how much more seriously the city is now treating erosion risk on this exact stretch of coast than it was just a year ago.
What a September Without the Swim Looks Like
The Cove hasn't gone anywhere, and neither has the rest of the neighborhood's early-fall routine. The beach and stairs at the Cove remain open as usual, with lifeguards on duty from 9 a.m. to sunset, and the viewing platform above the sand is still one of the better places in the city to watch the water on a clear morning. A few ways to spend the weekend that was supposed to have a swim in it:
- Walk the Coast Walk Trail from the Cave Store out over Goldfish Point for the same bluff-top views spectators usually get during the race, minus the crowds.
- Grab a table on Brockton Villa's patio, which sits directly above the usual race route and is worth the visit with or without swimmers passing below.
- Spend time at Ellen Browning Scripps Park, still the best lawn in La Jolla for watching the sea lions from a respectful distance.
- Mark the calendar for September 19, when the fifth annual BirdStock Music Festival gives the neighborhood its next big outdoor gathering.
- If you registered for the swim, decide between deferring to 2027 or sending your entry fee straight to the Prevent Drowning Foundation of San Diego County, which still benefits either way.
Race director Brennan told local reporters it was heartbreaking to spend nine months preparing for something and have it turn out not to be feasible. That's a fair way to describe how the whole coastline has felt this year. Nothing about La Jolla's shoreline is unstable in a way that should worry anyone taking a walk this weekend, but the sand, the sea lions, and the bluffs have all, separately, made it clear that this stretch of coast is behaving differently than it used to. Locals who've paid attention to all three stories now know something that a single-story write-up won't tell them: 2026 is the year La Jolla stopped being able to take its shoreline for granted.
