Bali issues coastal high-tide warning for 8–11 November

In brief: A new BMKG coastal-flood warning is in place for parts of southern Bali between 8 and 11 November 2026. The forecast concerns potentially elevated tides around the 9 November new moon. It does not report confirmed flooding across the island.

Southern shorelines in six jurisdictions are covered

The national meteorological agency's coastal-flood bulletin identifies southern Bali, including shoreline areas in Jembrana, Tabanan, Badung, Denpasar, Gianyar and Klungkung. A 6 November report by ANTARA, quoting the agency's Denpasar regional office, specifies the southern shores of Jembrana, Tabanan and Klungkung and the coastal areas of the other three jurisdictions.

BMKG based its warning on observed sea levels and tidal predictions. The approaching new moon on 9 November may increase maximum tidal levels, but the highest water is not expected at the same hour or even on the same day everywhere. No single island-wide peak time was given in the general warning.

These place names refer to exposed coastlines within the listed jurisdictions. They do not imply that every neighborhood, resort or building in those areas will flood, and the alert does not establish that flooding has already occurred.

Possible disruption for people living near the water

The regional meteorological office identified port cargo handling, coastal settlements, salt production and inland fish farming as activities that could be affected by unusually high tides. Residents, landlords and tenants close to the shoreline may face disruption at access roads, entrances or ground-level storage areas, depending on their exposure. Those property-specific conditions are not covered by the bulletin.

BMKG recommends checking updated maritime and weather information through its Info BMKG app and official @infobmkg and @bmkgbali channels. Local forecasts matter because the alert spans four dates while the timing of individual high tides varies from place to place.

As of 7 November, this is a forecast-based precaution. The cited notices do not announce an island-wide beach closure, an evacuation order or verified damage. Any local restrictions or newly reported impacts should be assessed against subsequent official announcements.
