The highest tides of the year typically hit in summer and winter \u2014 around each solstice. That\u2019s tracking so far this year, but a combination of natural phenomena and human-caused climate change are adding to the extremes of these normal cycles.<\/p>\n

The Long Beach Peninsula \u2014 a narrow stretch of homes on the sand between the ocean and Alamitos Bay \u2014 is one place where all of those forces are coming together.<\/p>\n

High water<\/p>\n

In mid-June, a combination of strong swell and high tides led to dramatic images of water splashing over sand berms, onto the boardwalk and into streets.<\/p>\n

This week and last, tides topped 7 feet again. Without the same swell, the results were less dramatic.<\/p>\n

Higher-than-average tides are normal for this time of year, but they\u2019re predicted to become the new normal overall by late century.<\/p>\n

\u201cWhat is happening rarely now will happen almost at every high tide when we get to the end of the century,\u201d said Mark Merrifield, an oceanography professor at Scripps.<\/p>\n

Merrifield said the recent tides have been high due to natural cycles related to the moon\u2019s position to Earth this time of year. It\u2019s also likely related to\u00a0El Ni\u00f1o, a natural climate pattern<\/a>\u00a0that warms the Pacific Ocean \u2014 and warmer water takes up more space, leading to higher sea levels.<\/p>\n

That warm water tends to peak at the end of the year, which means winter, during the next high tide season, is likely to be even more \u201ceventful,\u201d Merrifield said.<\/p>\n

On top of all that, pollution in our atmosphere\u00a0is contributing to the warming and higher sea levels as well<\/a>, experts told LAist. Since the Industrial Revolution, sea levels\u00a0have been rising at an increasing rate, according to NASA<\/a>.<\/p>\n

Long Beach\u2019s response<\/p>\n

The city of\u00a0Long Beach\u2019s climate action plan<\/a>\u00a0estimates sea levels will rise as much as 2 feet by 2050 and nearly 7 feet there by 2100.<\/p>\n

\u201cWe\u2019re going to see sea level going up much faster as we go into the latter part of the century,\u201d Merrifield said. \u201cI think at some point it will come down to understanding how to live with high water, which is not something we\u2019ve normally done.\u201d<\/p>\n

And those who know Long Beach\u2019s peninsula have noticed.<\/p>\n

\u201cThe tides that we\u2019re seeing now, we did not see in the past,\u201d said Todd Leland, Marine Bureau manager for the city. \u200a\u201cWe used to not have to build berms year-round. We\u2019d only have to do it on an occasional basis here on the peninsula.\u201d<\/p>\n

It\u2019s been in just the last 10 years that Long Beach has had to build sand berms to protect oceanfront properties from high tides and south swells, which the south-facing beach is particularly vulnerable to, Leland said.<\/p>\n

Six days a week, city workers truck sand from the wider, western side of the beachfront back to the peninsula to replenish the sand that gets sucked away by the water between the jetty and the breakwater down the beach.<\/p>\n

\u201cWe\u2019re running out of space to build the berms because we\u2019re not able to keep up with the sand movement,\u201d Leland said.<\/p>\n

To address that, the city hopes to break ground on a project later this year to dredge some 415,000 cubic yards of sand from the Alamitos Bay Channel and replenish the beach about 200 feet out again.<\/p>\n

\u201c\u200aWith 200 more feet of area to work with, we potentially might not have to make berms,\u201d Leland said.\u00a0The city had considered long-term plans<\/a>\u00a0to restore kelp beds and rocky reefs in front of the peninsula in part to help slow wave energy, but that effort has stalled.<\/p>\n

The view from the peninsula<\/p>\n

Charles Thomas has lived on the peninsula for 50 years. He married his wife on the beach in front of his house.<\/p>\n

\u201cIt used to be the widest part,\u201d he said. \u201cWe had a big 96-foot tent. It was a big party, and everybody had a great time.\u201d<\/p>\n

On a recent afternoon, just before high tide, water flooded over an eroded berm and underneath the lifeguard tower toward Thomas\u2019 house.<\/p>\n

\u201c\u200aWe could not fit that tent there anymore,\u201d Thomas said, shaking his head. Thomas said he supports the dredging project and hopes it will help more than the berms.<\/p>\n

Down the boardwalk, Siobhan Gadallah stood with her husband and son, watching the water splash over the berms. The young child squealed in glee as the water came onto the boardwalk.<\/p>\n

\u201cThe waves splash over pretty intensely, like to the point where I think it could knock over my 4-year-old pretty badly,\u201d Gadallah said. \u201c\u200aThankfully we haven\u2019t had any flooding [inside], but our entire porch has been pretty badly flooded.\u201d<\/p>\n

The family has rented here for two years, but they\u2019re not too worried about the long-term prospects. Moving from downtown Long Beach, their new place feels like \u201cliving in a different country,\u201d Gadallah said.<\/p>\n

\u201c\u200aAs long as you have those sandbags, they do their job pretty well,\u201d she said.<\/p>\n

As for the berms?<\/p>\n

\u201c\u200aI do think the berms help, although I\u2019m not a fan obviously,\u201d she said. \u201cI do think it creates some sort of barrier, but once it hits a certain point, it does absolutely nothing.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"This article was originally published by LAist on Tuesday, July 14, 2026.
