HUNTINGTON BEACH, Calif. (AP) \u2014 Jake Hemann grabbed a board and headed out to surf. But an hour later, he wound up sitting at the lifeguard station soaking his foot in a pail of hot water alongside four other beachgoers.<\/p>\n

It is a common scene at Bolsa Chica State Beach and some other popular beaches in Southern California<\/a> where the number of people being hit by the sharp, serrated caudal barbs found on the tails of stingrays has gone up significantly from a year ago as a marine heat wave<\/a> draws more stingrays \u2014 and people \u2014 to shore. <\/p>\n

Hemann, a 31-year-old tourist from New Mexico<\/a>, said he was learning to surf when he hopped off his board and landed on what he thought was a sharp stick. \u201cIt hurt pretty bad,\u201d he said, while sinking his throbbing foot into the hottest water tolerable to ease the pain. \u201cIt was radiating up to my ankle.\u201d<\/p>\n

Bolsa Chica and Huntington State Beaches reported more than 3,100 incidents so far this year, twice the number for all of 2025. The city of Huntington Beach’s 3.5-mile (5.6 kilometer) stretch of shoreline has reported more than 2,000 such incidents so far this year, more than during all last year, while more than 900 stings were recorded on San Diego\u2019s beaches during the first half of 2026, more than during the first six months of any of the past five years, lifeguard data shows. <\/p>\n

\u201cWe\u2019re definitely seeing an increase,\u201d said Bryan R. Etnyre, state park superintendent in northern Orange County. \u201cA lot of it is due to warming ocean temperatures that are consistently staying in the 60s. I don\u2019t think there was a week all winter where we dropped below 60 this year.\u201d<\/p>\n

Warmer water draws rays and people\n <\/p>\n

Round stingrays are found in Pacific Ocean waters from Panama to Southern California and are known to veer toward the shore when the swell is down and the water warm. <\/p>\n

In recent years, many species that feed on rays, such as sharks, sea lions and giant sea bass, have seen their populations dwindle, causing the number of stingrays to grow, said Chris Lowe, professor of marine biology and director of the Shark Lab at California State University, Long Beach.<\/p>\n

Rays are known to prefer warmer water, such as lagoons. Females prefer these waters to reproduce, and during the summer male rays have a higher metabolism that drives them to seek out food in the invertebrates along the shore, Lowe said.<\/p>\n

\u201cThey\u2019re really a subtropical species that is thriving at the end of its range because of climate change,\u201d Lowe said.<\/p>\n

The ocean already has been warming because of human-caused climate change<\/a>, according to meteorologists.<\/p>\n

Meanwhile, more people have been heading to beaches seeking outdoor recreation since the coronavirus pandemic. And when the water is warm, they are more likely to swim.<\/p>\n

When rays are stepped on, they instinctively flick up their tails, stinging people with venomous barbs. Lifeguards urge bathers to shuffle their feet as they enter the water as the movement often gets rays to slide out of the way without stinging.<\/p>\n

In Southern California, lifeguards can treat 10,000 stingray injuries a year, Lowe said.<\/p>\n

In Seal Beach, one area draws so many due to an influx of warm water from a nearby power plant it is known as \u201cray bay,” though lifeguards there haven\u2019t seen much change in stings this year.<\/p>\n

Using a 75-foot-long net, researchers swept up some 200 stingrays, each about the size of a dinner plate, on a section of the beach on a recent morning.<\/p>\n

\u201cThere can be so many that they actually carpet the bottom, like you can\u2019t see sand,\u201d Lowe said. \u201cDuring El Ni\u00f1os, we get more of them up from the south, and they come closer to shore. So this year, we\u2019re expecting record numbers.\u201d<\/p>\n

Sting advisory and booties aim to help\n <\/p>\n

Lowe said he is working with television stations to develop a stingray advisory to help reduce the number of people who get stung, and the number of rays that get squished. Rays help keep the beach healthy by feeding on small clams and aerating sediment.<\/p>\n

Many beaches use an app to notify bathers when there are multiple stings at a location. Meanwhile, a company has developed surf booties that claim to be barb-resistant \u2014 though swimmers are urged to still tread lightly to avoid trampling the rays.<\/p>\n

At Bolsa Chica State Beach, swimmers suffering stings to the sides of their feet and toes sat in a circle refilling their pails with hot water from a hose. Some were there more than an hour waiting for the pain to ease.<\/p>\n

Most stings don’t require additional medical attention. If redness and swelling continue more than four or five days, there could be a medical complication such as an infection or a retained barb that can be seen on an X-ray, said Dr. Christanne Coffey, who researches the stings at University of California, San Diego Health.<\/p>\n

Allen Lowry said he was playing with his 7-year-old grandson when he came down on something squishy. He lifted his foot and saw blood so his wife drove him to the lifeguard station for a hot water soak, which is the remedy for stings.<\/p>\n

Lowry, 69, said he swims three times a week at another beach, and getting stung, though painful, won\u2019t change that. He said some people in his swim group have been stung multiple times.<\/p>\n

\u201cUsually, once the pain you feel goes away, you feel fine the next day,\u201d he said.<\/p>\n
