Weather permitting, Parisians and tourists will be able to dive into dedicated sections of the river from July 5th, according to authorities.
The public will be able to access three bathing sites at bras Marie in the heart of the historic centre, the Grenelle district in the west of Paris, as well as Bercy in the east.
Last year, water treatment stations, holding tanks and connections to the Parisian boat sanitation system were installed.
'For the Games, we cleaned up three quarters of the Seine. And the water was 100 percent ready for bathing on dry days,' said Marc Guillaume, prefect for the Ile-de-France region that includes Paris.
According to Guillaume, the top state-appointed official for the region, the new bathing zones will be popular.
This year, the weather is predicted to be drier than the record rainfall during the Games, which had led to the cancellation of six of the 11 competitions held on the river.
'It was an extraordinary moment (in 2024), but swimming during the Games was not an end in itself,' Paris Mayor Anne Hidalgo told reporters in May.
'Making the Seine swimmable is first and foremost a response to the objective of adapting to climate change, but also of quality of life,' she added.
Last year, Hidalgo dove into the Seine in front of journalists from around the world before the Games began.
The historic swim signalled the end of years of efforts to clean the Seine and the river which flows into it, the Marne.
Work had started in the 1990s, with an initial investment of more than €9billion from the greater Paris sanitation authorities.

Following initial efforts, the 'bathing plan' leading up to the 2024 Paris Games was launched in 2016. The French state and local authorities had invested another €1.4 billion.
The plan was focused on preventing the city's waste waters from flowing into the Seine.
The mid-19th century Parisian sewage system often overflows on rainy days, causing rain and waste water to pour into the river.
Flags will inform bathers about pollution levels in the water every day, and if it rains the sites will likely close on the day after, said Paris city official Pierre Rabadan.
'We're not tossing a coin, we're relying on scientific data,' he said, adding that – contrary to some reports at the time – no athlete had fallen ill after swimming in the river last summer.
The presence of the fecal bacteria escherichia coli (E. coli) and enterococci in the Seine will be assessed daily using live sensors and samples.
According to the association France Nature Environment Ile-de-France, however, the planned tests are 'insufficient'.
There are 'many viruses which cannot be tested for' in the Seine, said honorary president of the association Michel Riottot.

Swallowing too much water from the river could lead a person to catch hepatitis, gastroenteritis or skin diseases, former research engineer Riottot told AFP.
Chemical pollution will not be measured either, added Riottot.
'If there is occasional pollution upstream, we will be informed, so we will be able to take necessary measures,' Rabadan insisted.
The number of species of fish in the Seine increased from four in 1970 to thirty-six reported in February – a sign that water sanitation has improved over the years.
In early June, the Paris City Council gave legal rights and a personhood status to the Seine to protect its fragile ecosystem, as part of a global movement to grant legal personhood to nature.

Three-time world champion figure skater Sakamoto to retire
"I think it's better for me to make this a clean break than to continue for two or three years," said the 25-year-old, who won team silver and singles bronze medals at the 2022 Beijing Winter Games. "I'll be 29 at the Olympics (in 2030) so I thought that's not possible," Sakamoto told reporters at an event in Kobe. "I want to finish every competition with no regrets, so I want to seek perfection more than ever before," she said. Sakamoto finished second at the world championships in Boston in March, missing out on becoming the first woman in 65 years to win four consecutive world crowns. She said after Boston that the experience would help her as she looked forward to the Milan Cortina 2026 Olympics. © 2025 AFP

Heatwaves in France: earlier, hotter, longer
"We have observed, in a very well-documented manner, that heatwaves are occurring earlier and earlier, longer and longer, and more intense," Météo-France forecaster François Gourand told Franceinfo . Although heatwaves are far from a new phenomenon, Météo France's records show that they are becoming more and more common as global temperatures rise. READ ALSO 'Avoid iced water and air-conditioning on max' - How the French stay cool in a heatwave Between 1947 and 2024, national forecaster Météo-France recorded 49 heatwaves - defined in France as an episode where temperatures are abnormally high for several days. Advertisement READ ALSO How hot will it get in France this summer? Between 1947 and 1957, four heat waves were recorded. This figure has increased fivefold over the last 10 years, from 2014 to 2024. They will become increasingly common by the end of the century. By 2050, when France will already be, on average, 2.7C warmer than the pre-industrial period, the number of heatwave days will increase fivefold again, according to Météo-France. And tenfold in a France 4C hotter than the pre-industrial period, by 2100. To put that into perspective, we're currently running at around 1.7C above pre-industrial norms. READ ALSO In Maps: The five worst French cities to spend a heatwave in Climate change is making France hotter on average. But heatwaves will get more intense. To calculate a national heatwave, Météo-France runs the numbers of the national heat index – it must exceed 25.3C for one day and 23.4C for at least three days for the French forecaster to declare a heatwave. Back during the deadly 16-day heatwave in 2003, when temperatures above 40C were recorded in Toulouse, Lyon, Dax and Orange, the national heat index rose past 29C. In 2019, a heatwave of shorter duration – when a new local record high temperature of 46C was set in the Hérault, the national heat index was higher still. READ ALSO How to get a good night's sleep in a French heatwave Beyond their accelerated frequency and intensity, these heatwaves are starting to hit France earlier and later in the summer. A mid-June heatwave such as the one we're entering here, which was once considered unseasonably early, is now increasingly common – while it has also become more common in recent years to experience these weather phenomena after August 15th. Our children, and our children's children are likely to endure heatwaves from mid-May all the way through to the end of September, experts warn.
