Heavy rainfall that began on Tuesday night (9 September 2025) has led to severe flooding in Bali, paralysing roads, damaging property, and disrupting daily life in several districts. West Denpasar is among the worst affected, with residential areas, businesses, and infrastructure submerged.
In Padangsambian, floodwaters entered houses and dormitories in the early hours of Wednesday.

Observers reported that the water began to rise around 3:00 AM local time, with homes inundated less than an hour later.
The water reached the thighs of adults, and in lower-lying areas, levels were as high as the waist. One open-top vehicle was left half-submerged, with only its upper body visible.
A number of main roads in Denpasar became impassable. In Jalan Kebo Iwa Selatan, floodwaters cut off traffic, while in Jalan Sulawesi near the Tukad Badung bridge, vehicles were stranded.
Circulating video footage showed streets turned into rivers, with an overflowing waterway worsening the situation. The intensity of the rain also caused structural damage, with a three-storey building collapsing as a result of the floods.
Widespread Flooding Across Denpasar and Surrounding Areas
As reported by Detik & Radar Bali, in several neighbourhoods of Denpasar City, such as Pura Demak and Gang Pucuk III Blok C in Ubung, water entered residential compounds.
In Banjar Dadakan, Peguyangan, the heavy current swept away cars and motorcycles, while also damaging Beji Pura Puseh Ubung Park.
The flooding was not limited to Denpasar. In Karangasem, heavy rainfall triggered landslides that blocked access to several areas, making evacuation and relief efforts difficult. In Tabanan, flooding left residential areas in Kediri submerged, with waters failing to recede.

By contrast, in Buleleng Regency, rainfall on Tuesday afternoon subsided by evening, and no significant disasters were reported in Singaraja.
Bali Floods: Regional Impacts and Official Response
The Bali Regional Disaster Management Agency (BPBD) confirmed that floods had affected nearly all parts of the island. Flood levels in some areas reached between two and three metres, submerging even two-storey houses.
“Almost all of Bali [is flooded]. The height varies, even some two-storey houses are submerged (with a height of) 2–3 metres,” said the Secretary of the BPBD, Gede Agung Teja Bhusana Yadnya, as reported by Kumparan.
He added that Denpasar had been the most heavily affected, with at least 43 locations still under response as of Wednesday morning.
“The most affected area is Denpasar. Denpasar currently has at least 43 locations that are still being dealt with. We cannot report the details yet because we are still dealing with it,” he stated.
Despite the widespread damage, Teja reported that no casualties had been confirmed. He explained that several factors had contributed to the flooding.
These included the high intensity of rainfall, the accumulation of rubbish, the impact of large-scale development projects, and waterways unable to cope with the excess water.
“This development is an infrastructure issue. The drainage network infrastructure must be good, and the flow of rivers is also disrupted due to the impact of development,” he said.
