Bali Braces for Another Intense Wet Season
With the dry season still gripping much of Bali in late September 2026, local officials are already looking ahead with concern. The island's rainy season typically begins in October and runs through March, but after the worst flooding in more than 70 years struck Denpasar in September 2025, authorities are treating preparation as urgent rather than routine.
The Denpasar City Council has publicly called on the city government to avoid complacency. Council members from multiple political factions have urged the Regional Disaster Management Agency (BPBD) and the Public Works and Housing Agency (PUPR) to clean drainage channels, normalize river flows, and establish early-warning systems before rainfall intensifies. Denpasar Mayor IGN Jaya Negara confirmed the city is already coordinating with the national river authority, BWS, because jurisdiction over several waterways sits with the central government rather than the municipality.
Which Areas Face the Highest Risk
The 2025 floods were not confined to Denpasar. Popular tourism corridors in Badung Regency, including Canggu, Seminyak, Kuta, and Uluwatu, were also affected. Rapid urban development across Bali has compounded the problem: the conversion of agricultural and greenbelt land into built-up areas reduces natural water absorption, pushing more runoff into already-strained drainage networks.
Falling trees and landslides are noted as common secondary hazards following major flood events, and council member Agus Wirajaya has specifically asked the city to accelerate tree-pruning programs in flood-prone streets.
A Broader Climate Warning
The stakes extend beyond one wet season. The United Nations has warned Indonesia and other countries in the Asia-Pacific region to prepare for a return to El Niño conditions in 2026 and 2027. El Niño typically intensifies weather extremes, and in Indonesia that can mean prolonged dry spells followed by sudden, heavy rainfall. The pattern is consistent with what Bali has already been experiencing: longer, more intense storms with shorter breaks between downpours.
Practical Advice for Travelers
For anyone planning a trip to Bali in the coming months, having a flexible itinerary is sensible. The Bali Sun, which first reported these developments, recommends preparing two versions of your travel plan so that outdoor activities can be swapped for indoor or covered alternatives when storms roll in. Real-time weather alerts in both English and Bahasa Indonesia are published by the Bali Meteorology, Climatology and Geophysics Agency on Instagram, which is a useful resource to follow before and during your stay.
Why It Matters for Hosts
Independent accommodation operators in flood-prone areas such as Canggu, Kuta, and Seminyak should review their own drainage and property-level flood preparedness now, before the season peaks. Practically, this means checking that gutters and ground-level drains are clear, confirming that your property's insurance covers flood damage, and creating a simple guest communication plan for severe-weather days. Guests who receive a calm, informative message from their host during a storm are far more likely to leave a positive review than those left to figure things out alone. Proactive communication during disruptions is one of the most cost-effective investments a small operator can make in guest satisfaction.
