Open water swimming at the 2025 World Aquatics Championships was held from 16 to 20 July 2025 at Sentosa Island in Singapore. The programme consisted of seven events, including three for men, three for women, and one mixed event. The 3 km knockout sprint events were included for the first time at the world championships. The water temperatures were unusually high for the world championships, and several swimmers needed medical treatment after swimming. Water quality issues also caused the first two events in the programme – the men's and women's 10 km races – to be postponed.

Germany's Florian Wellbrock won all four gold medals available to him in the open water events. It was the first time this had ever been achieved at the World Aquatics Championships. Australia's Moesha Johnson also won a medal in all the individual events available to her, including winning gold in the women's 10 km and 5 km.
Events
editThe programme consisted of a 10 km race, 5 km race, and 3 km knockout sprint, all of which had separate male and female races. The only mixed-gender event was the 4 × 1500 m relay.[1] All events were contested in the waters near Sentosa Island in Singapore.[2]
Achievements
editGermany's Florian Wellbrock won four gold medals, meaning he won every gold available to him in the open water events (the 10 km, 5 km, 3 km knockout sprint, and the mixed 4 × 1500 m relay).[3][4][5] It was the first time this had ever been achieved at the World Aquatics Championships.[6][7] Australia's Moesha Johnson won gold in the women's 10 km and 5 km events and bronze in the knockout sprint.[8]
Conditions
editHeat
editThe water temperature reached over 30.8 °C (87.4 °F), which means it was within 0.2 degrees of the upper limit of 31 °C (88 °F) that athletes were allowed to compete under.[9][10] The World Open Water Swimming Association wrote that the conditions were "among the most extreme ever faced at a world championships".[11] Several swimmers needed medical treatment and three were hospitalized.[11][12]
Postponements due to water quality
editBoth of the 10 km races, the first two events of the programme, were delayed due to high e. coli levels in the water.[13] The women's 10 km was delayed from 08:00 SGT on 15 July to 10:15 on 16 July,[14] and then it was rescheduled again to 16:00 on the same day.[13] The men's 10 km was postponed from 07:30 to 13:00 on 16 July.[13][15] The source of the contamination was unknown.[16]
Schedule
editSeven events were held from 16 to 20 July 2025.[1] After previously being contested at other international open water swimming events, the 3 km knockout sprint events were included in the World Championships for the first time.[17][18]
