Recent flooding in Bali left vast swathes of Denpasar and Badung regencies devastated.
With thousands of families experiencing damage to their homes and businesses, as well as massive damage to infrastructure, the incoming monsoon season will pose a severe test for communities across Bali, including the tourism industry.
Typically, the monsoon season in Bali arrives in late October or early November. However, climate and environmental changes have meant that the monsoon’s easy rains have been arriving earlier each year.
On the 10th September, Bali experienced the heaviest rainfall and worst flooding the province has seen in over 70 years. Flash flooding, landslides, and building collapses killed at least 18 people and left thousands of families with extensive and irreparable damage to their homes and business properties.
Extensive recovery efforts have been undertaken by local communities, NGOs, and government agencies over the last two and a half weeks, though with monsoon season not even officially underway yet, the risk of more natural disasters is very real in Bali right now.
The Head of the Meteorology, Climatology, and Geophysics Agency (BMKG) Region III, Cahyo Nugroho, has confirmed that there is an increased risk of coastal flooding this week in Bali and into the rainy season.
Nugroho explained that the Perigee phase phenomenon expected on the 7th October 2025 and the full supermoon phase between 7th-11th October 2025 could increase the maximum sea level. Tourists exploring the southern coast of Bali this week must be mindful of the potential for coastal flooding and sudden tidal swells.
Nugroho shared, “Based on water level data monitoring and tidal predictions, coastal flooding (tidal flooding) is likely to occur in several coastal areas of Bali, including the coasts of Gianyar, Kuta, Tabanan, Klungkung, and Karangasem.”
He added, “The public is advised to remain vigilant and alert to anticipate the impact of maximum sea tides and to pay attention to weather updates from the BMKG.”
Speaking separately, the Head of the Emergency and Logistics Division of the Karangasem Regency Disaster Management Agency (BPBD), I Nyoman Sokowijaya, reported that flood water was still standing at a height of around 30 cm, especially on village roads and plantation areas. With flood waters not yet receding in many water courses in East Bali, there is huge concern for the coming months.
Sokowijaya shared, “The government has made various efforts, such as pumping and coordinating with relevant parties, but this has been hampered by flooding in several districts and cities.” He confirmed that aid distribution to communities in the worst-affected areas is ongoing.
The Denpasar City Government has officially entered the ‘Emergency Transition Status’, which will be in effect until 17th December. This is the next phase of recovery after an official “State of Emergency’ has been declared, as was in place for the seven days after September’s floods.
The Mayor of Denpasar, I Gusti Ngurah Jaya Negara, told reporters, “Based on consideration from the Governor, the BMKG and the BPBD, the status of Disaster Emergency Response has been changed to Emergency Transition Status to Recovery for three months.”
He added, “Even though the status has changed, services to affected residents will continue until completion, so that improvements in vital sectors, infrastructure, schools, and the community’s socio-economic recovery can be achieved.”
Tourists traveling to Bali in the coming months are advised to follow the Bali BMKG on Instagram for the latest weather warnings and natural disaster updates, and to ensure that they have fully comprehensive travel insurance prior to travel.
Tourists should be sure to read through all their policy documents prior to travel to ensure that they understand what cover and protection they are entitled to in the event of an emergency or natural disaster, and how to access support and make a claim.
