Liputan6.com, Jakarta Bali, one of Indonesia's iconic destinations, is now in the spotlight.
The province was hit by flash floods on September 9 and 10, 2025, following persistent, extreme rainfall.
This situation was exacerbated by further heavy rains on September 15, 2025, causing widespread flooding in various areas, including the popular tourist area of Canggu.

The Bali floods not only caused significant infrastructure damage, but also claimed lives and forced hundreds of residents to evacuate.
Various factors, from atmospheric phenomena to land use change, contributed to the scale of the damage caused by the Bali floods.
Widespread Impact and Losses from the Bali Floods
The Bali floods in September 2025 affected six regencies/cities in Bali, including Denpasar, Jembrana, Gianyar, Klungkung, Badung, and Tabanan.
Popular tourist areas such as Seminyak, Canggu, and Ubud experienced flooding and blocked roads, disrupting the activities of residents and tourists.
The most devastating impact was the loss of life, with at least 17 to 18 people killed after being swept away by the floodwaters, with several others still missing.
More than 250 families, or 620 people, were forced to evacuate, seeking temporary shelter from the raging waters.
The material losses caused by the Bali floods were enormous, estimated at over 25 billion IDR (1,500,000 USD).
Hundreds of homes and community buildings were damaged, roads were submerged, and several bridges were washed away.
In Denpasar alone, 474 shophouses were reported to have suffered severe damage due to the floodwaters.

Canggu and Berawa are Highly Damaged by The Floods.
The tourist areas of Canggu and Berawa in North Kuta were among the worst-affected areas by the Bali floods on September 15, 2025.
Main roads in Canggu, such as Jalan Canggu Padang Linjong, Jalan Pantai Batu Bolong, and the Canggu-Tibubeneng shortcut, became impassable to vehicles.
In Berawa, floodwaters submerged vehicles and homes on Jalan Sri Kayangan, causing panic among residents.
The flooding in both areas was triggered by local rivers overflowing due to the drastically increased water levels following incessant heavy rain.
The Badung Housing and Settlement Agency (Perkim) responded quickly by deploying suction pumps to speed up the receding waters in Berawa.
Government's Rapid Response to Floods
In response to this emergency situation, Bali Governor Wayan Koster declared a one-week disaster emergency response status starting September 10, 2025.
Vice President Gibran Rakabuming Raka inspected the flooded areas in Denpasar on September 11, 2025, and distributed aid.
The following day, President Prabowo Subianto also visited Bali, inspecting affected areas in Denpasar and Jembrana, and promising additional assistance for Bali flood victims.
Indonesian Tourism Minister Widiyanti Wardhana has visited Bali to assess the extent of damage caused by last week's floods.
Just two weeks ago, Minister Wardhana had to issue a statement affirming that the country was safe to visit after political rallies were held across the country, and this week she has issued more statements affirming safety following the floods.
“We have checked that there are no cancellations at all from tourists, no flight or hotel cancellations, even though it is very full, it is normal.”
The Ministry of Environment (KLH) launched a Strategic Environmental Assessment (KLHS) evaluation of the Ayung River Basin, and the Balinese government suspended new hotel permits in response to the disaster.
Environment Minister Hanif Faisol Nurofiq emphasized the importance of waste management at source to prevent a recurrence of the Bali floods.

Causes and Long-Term Impacts
The primary cause of the Bali floods was extreme heavy rainfall, exceeding 385 mm in a single day, equivalent to an entire month's rainfall.
Environment Minister Hanif Faisol Nurrofiq confirmed that the massive flooding in Bali was triggered by extreme rainfall.
The southern region, from the center to the coast, was the most affected.
He stated that at least half of the region is experiencing serious ecological stress.
The atmospheric phenomena of the Rossby and Kelvin equatorial storm surges contributed to this extraordinary intensity of rainfall.
However, environmental factors also exacerbated the impact of the Bali floods.
Inadequate drainage systems, piles of garbage clogging rivers, and land conversion from rice fields to residential and commercial areas have reduced the soil's ability to absorb water.
