BPBD asked the public, especially those living in coastal areas of Jakarta, to be aware of the potential peak of coastal flooding or tidal flooding that occurred on December 5, 2025.
"Rob is predicted to occur on December 4-6, 2025, with a peak time of December 5 at 09.00 WIB. Residents in the coastal area of Jakarta are advised to be aware of sea level increase," said Head of BPBD DKI Jakarta Isnawa Adji.
Isnawa explained that there were 6 areas that were mapped the most affected by tidal flooding, namely the Kamai, Muara Angke, Baywalk Pluit, Sunda Kelapa, RE Martadinata, and Blencong Marunda areas.
"Residents in these six areas are advised to increase vigilance and continue to monitor information from official information channels," said Isnawa.
The inundation and flood information channels managed by the DKI Provincial Government include the monitoring site banjir.jakarta.go.id, the JAKI application, and the DKI Jakarta BPBD social media.
Isnawa revealed that the potential for rob this week was compiled from information from the BMKG Meteorological Station Class I Maritime Tanjung Priok regarding the early warning of tidal flooding. Based on BMKG information, the potential for tidal flooding this time is due to the phenomenon of the full moon and perigee (suprmoon).
