BMKG Warns of Maximum Tides Along Six Bali Coastal Areas

Mangupura — The Meteorology, Climatology, and Geophysical Agency (BMKG) Region III Denpasar warned of potential maximum sea tides in six Bali coastal areas from 9–18 October 2026. The areas covered are the southern coast of Jembrana Regency, the southern coast of Tabanan Regency, the coast of Badung Regency, the coast of Denpasar City, the coast of Gianyar Regency, and the southern coast of Klungkung Regency.

The warning was issued to increase awareness of possible sea-level rises during that period. The timing of maximum tides may differ by area, both by day and by hour, so impacts will not occur simultaneously along Bali’s entire coastline.

BBMKG linked the potential tides to the new-moon phase expected on 10 October 2026. The phenomenon may increase maximum sea levels in several Bali coastal areas.

Tides may disrupt ports and coastal settlements

For residents, workers, and visitors in coastal areas, the warning means that activities near the shoreline may be affected by rising sea levels. Sectors requiring attention include cargo loading and unloading at ports, activities by residents in coastal settlements, salt-farming operations, and inland fisheries.

BBMKG asked coastal communities to monitor local conditions because the timing of maximum tides varies. The agency also directed the public to follow maritime weather information through the official channels of BMKG Region III Denpasar during the 9–18 October 2026 warning period.

BMKG’s national warning on coastal flooding also lists Bali’s southern coast, including Gianyar, Badung, Denpasar, Tabanan, Klungkung, and Jembrana, for the same period. The information is based on monitoring sea-level data and tidal forecasts.
