BMKG Warns of High Tides Along Bali’s Southern Coast

Denpasar — The Balai Besar Meteorologi, Klimatologi, dan Geofisika (BBMKG) Region III Denpasar is warning of potential maximum high tides along parts of Bali’s southern coast from Sept. 26 through Sept. 30, 2026. The areas named in the forecast are southern Jembrana Regency, southern Tabanan, Badung, Denpasar City, Gianyar and southern Klungkung.

The warning coincides with the full-moon phase on Saturday, Sept. 26, which BBMKG official Cahyo Nugroho said could increase the maximum sea level. The phenomenon may affect port operations, coastal settlements, salt cultivation and fishing businesses.

Why it matters for residents and visitors

For foreign residents and visitors, the warning applies to coastal areas and activities connected to the sea during the five-day period. Ports, shoreline settlements and maritime businesses in the listed parts of Bali may face disruption if high water reaches facilities or access routes. The reports do not specify closures or a separate timetable for individual beaches, ports or businesses.

The affected coastline spans six administrative areas. They include the southern coast of Jembrana Regency and Tabanan, the coast of Badung, Denpasar City, Gianyar and the southern coast of Klungkung. BBMKG’s forecast identifies the full moon as the factor associated with the potential rise in maximum tides.

The reported period begins on Sept. 26 and ends on Sept. 30, 2026. The warning concerns potential high tides rather than a confirmed inundation across all named locations, and the reports do not state that Bali’s ports or coastal attractions will close.
