Official bulletins highlight drought, not imminent extreme flooding in Bali

Denpasar — Bali’s disaster agency is currently warning of meteorological drought

The provincial disaster management agency (BPBD Bali) issued a “Peringatan Dini Cuaca/Iklim Dasarian II September 2026 Provinsi Bali” bulletin dated 10 September 2026, noting that Bali remains in the dry season for the second ten-day period of September and highlighting an early warning for drought risk, not heavy rain or flooding. A detailed article by BPBD Bali explains that from 11–20 September 2026, the province is still experiencing the dry season and that there is no early warning for high rainfall

The same BPBD communication describes forecast conditions for three consecutive sub-periods between 11 and 20 September. It reports potential light rain

Current official warnings

BPBD Bali’s early warning emphasises drought-related hazards rather than flooding. The bulletin identifies a “peringatan dini kekeringan meteorologis” (early warning for meteorological drought) for parts of the province for 11–20 September 2026. BMKG’s climate early warning table for the same period lists Bali among provinces affected by potential meteorological drought, with some areas flagged for heightened vigilance.

Local media coverage of the BPBD bulletin confirms this focus. An 11 September 2026 report from a Bali-based outlet, citing BPBD Bali head I Gede Teja, states that Bali is still in the dry season for Dasarian II September 2026 and reiterates that there is no early warning for high rainfall in that period, while light rain is possible across several districts.

Neither BPBD Bali’s bulletin nor BMKG’s national climate analysis describe or quantify a recent flood event in Bali with 18 fatalities, 149 displaced residents or rainfall exceeding 200 millimetres per day at southern Bali stations, and they do not attribute such impacts to overflow from the Ayung river basin.

Flood risk and preparedness in Bali

Separate BPBD Bali publications confirm that flooding remains a recognised hazard on the island, particularly in urban river corridors. A January 2026 BPBD article describes the installation of six flood-warning sirens along Tukad Badung in Denpasar, from Kampung Jawa to Pekambingan, to provide early alerts for residents, traders and visitors near Pasar Badung and Pasar Kumbasari when flood potential is detected. The siren system is presented as part of broader efforts to reduce flood risk and improve community preparedness.

BPBD Bali also maintains risk maps and a provincial disaster risk assessment for 2025–2029, which identify areas exposed to hydrometeorological hazards, including flooding, and support planning for mitigation and early warning systems. These documents underline that land use, river management and drainage capacity are important factors in how intense rainfall translates into on-the-ground impacts, even though the current September 2026 bulletins focus on drought.

Guidance for residents and visitors

Based on the latest BPBD and BMKG information, there is no active extreme rainfall or flood early-warning bulletin

For those living in or visiting river-adjacent urban areas such as central Denpasar, BPBD Bali’s earlier flood preparedness measures — including warning sirens along Tukad Badung and planned improvements to early warning systems — illustrate the importance of staying alert during periods of heavy local rain and following any instructions from local authorities. Accommodation operators in such areas may wish to familiarise themselves with access routes, drainage conditions and local alert mechanisms to support guests should a flood warning be activated.

In summary, while Bali’s disaster management agencies continue to treat flooding as a significant long-term risk and have invested in river-based warning systems, the most recent official bulletins for mid-September 2026 describe a dry-season context with light rain potential and a primary focus on drought rather than imminent severe flooding.
