BMKG warns of high tides across six Bali coastal areas

Mangupura — The Meteorology, Climatology and Geophysics Agency’s Denpasar regional office has issued an early warning for maximum high tides along six Bali coastal areas from Oct. 9 to 18, 2026. The areas are the southern coasts of Jembrana and Tabanan, Badung, Denpasar, Gianyar and southern Klungkung.

The warning covers a period when coastal water levels could rise significantly. The agency said the potential is linked to the new-moon phase expected on Oct. 10, 2026. The timing of the highest tides will differ by location, including by day and hour.

For foreign visitors and residents, the warning concerns coastal activities rather than a general restriction on travel. Conditions may affect ports, shoreline settlements, salt farms and inland fisheries. Visitors using beaches, waterfront facilities or port services may encounter changing conditions during the warning period.

Why it matters for Bali visitors

High tides can affect access and operations in low-lying coastal areas, especially around ports and other waterfront facilities. The warning gives businesses and travelers a defined period in which to monitor local marine conditions, while recognizing that the precise timing will vary among the six areas.

The agency urged coastal communities to remain alert throughout the period and to follow maritime-weather updates from its official channels. The national agency’s maritime warning also identifies southern Bali’s Gianyar, Badung, Denpasar, Tabanan, Klungkung and Jembrana coasts as potentially affected from Oct. 9 to 18, 2026.

No blanket closure or travel ban was stated in the reports. The next step identified by the agencies is continued monitoring of official maritime-weather information, because the maximum-tide timing differs across locations.
