Heavy surf, high tides and rip currents have done some damage to the Southern California coast, with potentially dangerous conditions expected to last at least until Thursday.

The conditions already have had devastating consequences. Just last week in Laguna Beach, a 5-year-old girl drowned after she was swept into the ocean by powerful surf. Authorities said they were able to rescue her mother and brother, who were caught in the same swell.

In Crystal Cove State Park, tides over 7 feet and heavy surf damaged part of a historic cabin, and nearly flooded another. A lifeguard tower was nearly pulled into the water.

'Biggest waves I've ever seen'

“ At the peak of it, just the biggest waves I've ever seen here in my experience as a lifeguard,” said Jake Beckley, who’s been a Crystal Cove lifeguard for six years. “We've lost pretty much the entire beach at certain points.”

The tide reached as high as The Beachcomber restaurant at one point, and pulled chunks of a historic seawall from beneath a cabin nearby.

Sandra and Rigo Garcia of San Dimas have been visiting Crystal Cove to stay in those historic cabins since the late 1990s. They’ve seen the beach change over the decades.

“The tide is just so high that it took all the sand, and we're just like, ‘Oh, where's my beach?’” Sandra Garcia said as they sat under an umbrella on the sand of a small road.

Rigo Garcia pointed to the patch of sand in front of them.

“This spot was always the greatest spot, because I would come early in the morning, set up the easy-ups and chairs, and we always had plenty of real estate,” he said. “The kids would be able to swim maybe 10, 15 yards while they're out there. But now it's so dangerous…too many rocks.”

How we got here

A strong southern swell, combined with high tides, has led to the coastal erosion and flooding. The highest tides of the year, however, usually come in the winter, but over the last week some beaches have seen record high tides for this time of year, according to the National Weather Service.

Riley Pratt, an environmental scientist with California State Parks Orange County District, said these events are a window into the future — as pollution in our atmosphere heats up the planet and melts glaciers, sea levels rise.

“As sea levels rise, things like this are gonna become more common, and their impact is going to be proportionally greater because the baseline is shifting,” he said. “That's going to change what is this just annual cycle into something that's new and that we haven't seen before.”

But for now, the beach is crowded, the sun is shining, and summertime is in the air. And for the Garcias and their fellow beachgoers, there’s no time like the present.

“Earth changes, so you have to go with it,” said Sandra Garcia. “Even though it has changed so much, we still can enjoy it… and be thankful that we have this paradise here.”

What's next

In Orange County, the National Weather Service warns that dangerous surf conditions, including rip currents, are expected to continue through Friday evening.

This creates dangerous conditions for swimming. Anyone caught in a rip current is advised to swim parallel to the shore to clear it. And, as the NWS says, "always swim near a lifeguard."

In L.A. County, conditions are expected to continue through Wednesday night, including coastal flooding, high tides and rip currents.
