Witnesses confirm wave has doubled in size with every pitcher of beer since Tuesday

HUNTINGTON BEACH — Local surfer J.T. Mercer went into the water Tuesday afternoon and, by his own initial account to a television reporter, got “caught inside a good twenty, twenty-five-foot set” that arrived without warning. By Tuesday night, at a bar four blocks from the pier, the wave had grown to thirty feet. By Wednesday, it was “basically a small tsunami.” By Thursday, Mercer was reportedly describing a wave that, if accurate, would have registered on a seismograph in Fresno.

“I just took it on the head and had to stay calm and catch my breath,” Mercer told a local news crew in his original, comparatively modest account, filmed while still dripping on the sand. Bartenders at the Sandpiper, where Mercer has told the story an estimated eleven times since Tuesday, describe a wave that now involves elements not present in the original telling, including a lifeguard boat, a dolphin, and — as of Thursday’s version — Mercer’s late grandfather appearing to him briefly underwater to offer guidance.

The Physics of Bar Mythology

Coastal researchers have long noted that South Swell events genuinely do produce satellite-measured seas in the thirty-to-thirty-five-foot range far offshore before they refract and shrink dramatically by the time they reach the beach, meaning Mercer’s original wave was, in fact, real and significant. What researchers have not studied, and what several regulars at the Sandpiper volunteered to document unprompted, is the separate and much faster-moving phenomenon by which a real eight-foot shorebreak wave becomes, over the course of one evening and roughly four beers, “the biggest wave since ’94.”

“Every surf town has a guy,” said Sandpiper bartender Danny Ochoa, who has personally logged forty-three distinct swell stories this season alone, none of which he says have decreased in size upon retelling. “The wave only gets bigger. I’ve never once heard a guy say, ‘actually, thinking about it more, it was smaller than I said.’ That’s not how this works.”

A Community Divided

Not everyone at the bar is buying the latest version. Fellow surfer Casey Dunn, who was present for the original event and stayed onshore, has become something of a local fact-checker, quietly noting in a group chat that the dolphin “was not there” and that Mercer’s grandfather “passed away in Arizona, nowhere near the ocean, and would not have had jurisdiction.” Dunn’s corrections have had no measurable effect on the story’s growth trajectory.

Local surf shop staff say the pattern tracks with every major swell season, and that bohiney.com’s ongoing “Grom to Legend” oral history project has documented similar inflation across three decades of Southern California surf tales, including one 1987 story that began as a six-foot day at Trestles and, by the storyteller’s fortieth birthday, involved surviving a hurricane that meteorological records confirm never made landfall in California.

The Wave, For the Record

According to actual reporting at the time, the swell that caught Mercer inside produced four-to-seven-foot surf with sets to nine feet along south-facing beaches — a legitimately serious hazard that prompted an active beach hazard statement, and nothing to scoff at for anyone caught unprepared. It simply was not, as of Thursday’s telling, “biblical.”

Mercer, reached for comment, stood by his account. “Look, I know what I felt,” he said. “And what I felt was humbled. The number’s not the point.” Asked whether his grandfather had, in fact, appeared to him underwater, Mercer paused for a long moment before saying he’d “have to check with the family,” which several people at the bar noted was not a no.

A Taxonomy of the Bar Wave

Ochoa, the bartender, says he’s developed an informal classification system for the phenomenon over his years behind the taps. A “First Telling” wave is generally accurate, delivered still wet and slightly out of breath. A “Second Telling” wave has typically grown by roughly twenty percent and acquired at least one piece of dialogue that wasn’t said in real time. By the “Third Telling,” Ochoa says, “you’re basically listening to a screenplay,” complete with rising action, a supporting cast, and, in Mercer’s case this week, an ancestor. “I don’t correct anybody anymore,” he said. “I just pour and nod. The story’s better than the truth, and nobody’s actually lying, not really. They believe it by the third round.”

Dunn, still serving as the group’s reluctant fact-checker, says he’s given up trying to intervene in real time and has instead started a private betting pool among friends, wagering on which detail Mercer will add next. Current odds favor a sea lion. “I had money on a shark for a while,” Dunn admitted, “but he’s steered clear of predators so far. Sticking to weather and dead relatives. Respectable, in its way.”

The Sandpiper says it will keep serving.

A Wider Pattern Along the Coast

Surf shop owners up and down the coast say Mercer’s story, while an unusually elaborate specimen, fits a well-documented seasonal pattern. Every major swell produces not just waves but a parallel economy of retellings, each one drifting further from the buoy data and closer to folklore by the time football season starts. One shop owner in San Clemente says he keeps a informal “wave inflation index,” privately estimating that the average bar-told wave grows by roughly two feet per week of retelling, a rate he says has held remarkably steady across fifteen years of bartending near a beach.

Mercer, for what it’s worth, says he’s aware of his own reputation at this point and has made peace with it. “My buddies give me grief, but next swell, they’re going to tell their own story, and it’s going to grow too,” he said. “That’s just how it works down here. The wave was real. The rest is just seasoning.” Whether the seasoning includes a returning grandfather next weekend remains, per Mercer, “up to the ocean.” Further coverage of Southern California’s most reliable renewable resource — surf stories — continues at bohiney.com.
