TEMPO.CO, Jakarta - Several areas in Bali were struck by severe flooding following extreme rainfall on the night of Tuesday, September 9, 2025. According to the National Disaster Management Agency (BNPB), the flood affected 202 families, totaling 620 individuals, as of Wednesday, September 10.
Many residents were forced to evacuate as their homes were submerged, and the flood also damaged buildings and public facilities. BNPB continues to update data on the impact of the disaster across the island. Here’s what is known so far:
1. Nine Fatalities and Missing Individuals
BNPB confirmed nine deaths caused by the floods, with data updated on Wednesday evening, September 10, at 18:45 WITA. Denpasar City recorded five casualties, Jembrana Regency two, and Gianyar and Badung Regencies one each.
Additionally, six people remain missing. A joint search operation led by the National Search and Rescue Agency (Basarnas) has deployed 100 personnel to locate them.
2. Floods Impact Six Districts and Cities
Abdul Muhari, Head of BNPB’s Data, Information, and Communications Center for Disaster Management, said six districts/cities were affected: Denpasar City, Jembrana, Gianyar, Klungkung, Badung, and Tabanan.
Denpasar City: 5 fatalities, 2 missing
Jembrana Regency: 2 fatalities; 103 families (200 individuals) affected
Gianyar Regency: 1 fatality

Evacuations are underway in several areas. In Jembrana Regency, 85 people have been displaced and are staying in shelters including Yeh Kuning Village Hall, Assidiqie Mosque, and Darul Musthofa Mosque.
3. Extreme Rainfall
The intensity of the flood is reflected in data from the Meteorology, Climatology, and Geophysics Agency (BMKG). Jembrana Station recorded 385.5 mm of rainfall on Tuesday night—more than twice the threshold for extreme rainfall of 150 mm per day. Denpasar Station reported 188.4 mm.
The heavy rain lasted over 24 hours, especially in Denpasar City, since early Tuesday. BMKG had previously issued an alert in its weekly weather outlook on Monday, warning of heavy rainfall accompanied by lightning and strong winds from September 9–11.
The agency also noted, “Entering the second week of September, an increase in rainfall is potentially expected in some areas of Java, Bali, and Nusa Tenggara.”
4. I Gusti Ngurah Rai Airport Declared Force Majeure
I Gusti Ngurah Rai Airport in Bali was declared in a state of force majeure, though flight operations continued as normal until Wednesday night.
Gede Eka Sandi Asmadi, Head of the Communication and Legal Division, said the airport and stakeholders maintained service standards despite the floods.
Airlines were advised to inform passengers about possible delays, as some key access points to the airport were paralyzed, and alternative routes might be needed.
“We have coordinated with all airlines to anticipate passengers who may experience delays and require special handling such as rescheduling,” Eka Sandi added.
