Guests staying in Bali villas and long-term renters should be aware that Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) has issued a high tide alert for several coastal areas of Bali from November 8 to 11, 2026. This advisory highlights the possibility of unusually high sea levels that could impact coastal communities and activities during this period.
Areas Affected by the High Tide Alert
The BMKG’s Region III office in Denpasar has identified six key areas along Bali’s coastline where elevated tides may occur:
- Southern Jembrana
- Southern Tabanan
- Coastal zones of Badung
- Denpasar’s coastline
- Coastal areas of Gianyar
- Southern Klungkung
These regions include popular tourist destinations and villa locations, especially along Bali’s southern shores. However, it is important to note that not every beach or coastal spot within these districts is expected to experience flooding.
Why Are Tides Higher During This Time?
The alert coincides with the new moon on Monday, November 9, 2026. During new moons, the gravitational forces of the sun and moon align, which can cause higher than usual tides, known locally as banjir rob. This phenomenon can lead to seawater inundating low-lying coastal areas temporarily.
Potential Impacts for Villa Guests and Coastal Residents
Higher tides may disrupt normal activities near the shore, including:
- Loading and unloading operations at local ports
- Salt farming and inland fish farming activities
- Access to some coastal residential areas
While the BMKG has not called for beach closures or banned swimming, visitors and residents should remain cautious, especially in low-lying zones that could experience temporary flooding.
Safety Recommendations
- Monitor local weather and sea condition updates regularly.
- Stay informed through BMKG’s official website, the Info BMKG mobile app, or their social media channels (@infobmkg and @bmkgbali).
- Be prepared for varying tide times and heights, as peak tides will differ by location.
- Avoid unnecessary activities near vulnerable shorelines during the alert period.
For those planning to stay in Bali villas near the coast, it is advisable to check with your villa management about any precautions or updates related to the high tide alert.
By staying informed and cautious, guests and residents can enjoy Bali’s beautiful coastal environment safely during this period of elevated tides.
