Emergency services were called at around 5.45am to concerns for the welfare of three women in the sea off Brighton, with three bodies being retrieved near Madeira Drive.
The RNLI said the Brighton lifeboat and Shoreham all-weather lifeboat had been launched at around 6am this morning, but that they have since been stood down.
Police are conducting "fast-moving" enquiries to confirm the identities of the women and understand exactly what has happened.
Chief Superintendent Adam Hays said that while the incident will be "concerning for the community... I would ask the public to stay away from the scene at this time while emergency services continue their work".
"We will provide further updates as soon as they are available," he added.

An aide to Kate described the two-day visit to Reggio Emilia, Italy, as a "really significant moment", having not undertaken an official foreign tour since 2022, when she went to Boston in the US for her husband's Earthshot Prize award ceremony.
The future queen will be in the northern Italian city to promote her work with The Centre for Early Childhood and learn about the "Reggio Emilia approach" to early years development.
The city pioneered the teaching method that has become recognised across the globe, stressing the importance of parents, educators and the environment in helping children grow.
Early years support has been central to Kate's public work for more than a decade. She founded the Centre for Early Childhood in 2021 to raise awareness of the importance of early years' experiences and to commission research.
She will be recognised for her efforts in Reggio Emilia with the Primo Tricolore, the city's highest honour.
During a reception at its town hall, Kate will meet civic leaders and key figures behind the city's education philosophy and will later meet members of the public in the square outside.

The visit comes two years after she went public with her diagnosis of an unspecified cancer in March 2024. She underwent chemotherapy and announced she was in remission in January 2025.
Her aide said: "Undoubtedly, this is a huge moment for the princess. Although there will be many highlights of 2026, I think being her first official international visit post her recovery [...] is a really significant moment for her."
During the six-month-long pilot, live facial recognition (LFR) cameras in static locations were stationed on Croydon High Street, in south London, instead of on vans.
Between October last year and March, the Metropolitan Police said 173 suspects were arrested for crimes including kidnapping, rape and serious sexual assault using the tech.
Officers said the cameras were used in 24 operations, including the arrest of a 36-year-old woman who was wanted for failing to appear at court for an assault in 2004.
The force also said a 31-year-old man who had been wanted for voyeurism for more than six months was arrested during the trial, as well as a 41-year-old man who was wanted over a rape in November.
During the trial, the force added that crime in the area reduced by 10.5% and there was a 21% reduction in violence against women and girls.
More than 470,000 people walked past the camera during the pilot. There was one false alert, where the person was spoken to by officers and then allowed to leave.

Lindsey Chiswick, national and Met lead for live facial recognition, said the results of the trial "show why live facial recognition is such a powerful tool when it's used carefully, openly and in the right places".
She added that "the public can see the difference", and said: "We will continue using static cameras in Croydon as part of our regular live facial recognition deployments, which play a vital part in keeping London safe."
It comes after it was announced that facial recognition technology would be rolled out across the UK in April after a legal challenge against the Met from two claimants failed.
Youth worker Shaun Thompson, one of the claimants, said he was misidentified by the technology used by the force. The other person bringing the claim was Silkie Carlo, from the group Big Brother Watch.
Judges ruled the claimants' human rights had not been breached and the Met Police's policy gave an "adequate indication of the circumstances in which LFR will be used".
They also said the argument the technology risked discriminating against people due to their race had not been convincing.
Thirteen forces were using LFR by the end of last year, and the home secretary said in January the number of LFR vans would increase from 10 to 50.
However, Essex Police paused its use of the technology earlier this year due to racial bias concerns.
The two tech titans are at the centre of a California court battle over the firm behind ChatGPT.
Mr Musk, who gave evidence last month, has accused Mr Altman, OpenAI and its president, Greg Brockman, of wooing millions of dollars from him between 2015 and 2017, when it was a non-profit, and then in 2019 moving to transform it into a corporate entity to enrich themselves.
The launch of ChatGPT in 2022 transformed the company into one of the most powerful tech firms, and Mr Musk has suggested that the "not trustworthy" Mr Altman being in charge is "a very big danger for the whole world".

Under questioning in court on Tuesday, Mr Altman refuted the Tesla mogul's bid to paint him as unreliable.
"I believe I am an honest and trustworthy businessperson," he said.
Pressed on whether he had "misled people" while doing business, he replied: "I do not think so."
Mr Altman also denied the accusation that he had tried to "steal a charity" with his leadership of OpenAI, which is preparing for a possible initial public offering that could value it at $1trn (£739bn).
He said Mr Musk had not opposed the plan to create a for-profit arm of the firm in 2019, claiming the SpaceX boss knew about the plan before he quit the board the year before.
He claimed Mr Musk once demanded a 90% stake in OpenAI, which made him feel "extremely uncomfortable".
"I don't think Mr Musk understood how to run a good research lab," he added.
"He had demotivated some of our most key researchers."

Testimony in the trial could conclude later this week, and jurors could begin deliberating whether the defendants are liable within days.
Mr Musk, the world's richest person, wants $150bn (£111bn) in damages from OpenAI and investor Microsoft, to be paid into a non-profit, and wants Mr Altman and Mr Brockman removed from their roles.
OpenAI claims he is only suing because he regrets leaving the board and missing out on potential riches.
It comes after he revealed he had stage four glioblastoma, an aggressive form of brain cancer. He first disclosed his treatment for the disease in September.
His family said they were "heartbroken" to announce his death in a statement on Tuesday.
"Jason changed lives in unexpected ways and was an inspiration to all who knew him and to those who admired him from afar," they added. "Our family will miss him dearly."
Collins made history in 2014 when he made his debut for the Brooklyn Nets, having become the first male athlete in America's top professional sports leagues to come out as gay. He was a 12-year veteran of the NBA at the time.
He also played for the Houston Rockets, Memphis Grizzlies, Minnesota Timberwolves, Atlanta Hawks, Boston Celtics, and Washington Wizards.
He received widespread support when he came out in an article for Sports Illustrated in 2013, including from then US president Barack Obama, who described him as a "terrific young man".

Speaking at the White House after Collins came out as gay in April 2013, Obama said: "One of the extraordinary measures of progress we've seen in this country has been the LGBT community deserves full equality, not just partial equality. Not just tolerance, but recognition that they're fully part of the American family.
"Given the importance of sport in our society, for an individual who has excelled at the highest levels in one of the major sports to go out and say, 'This is who I am,' I'm proud of it."
Collins attended the 2014 Obama State of the Union address as a guest of the first lady, Michelle, and also spoke at the United Nations.
His former agent Arn Tellem said his legacy was one of "tolerance, dignity, respect, inclusion, compassion, and understanding", adding: "He left this world better than he found it."
