What BMKG’s Flores–Alor coastal-flood warning means for travellers

Flores — BMKG’s coastal-flood warning covers the Flores–Alor coastline from 7 to 11 November 2026. The warning concerns possible coastal flooding, or rob, in parts of East Nusa Tenggara during that period.

BMKG, Indonesia’s Meteorology, Climatology and Geophysical Agency, says a new-moon phase on 9 November 2026 could increase the maximum sea level. Water-level monitoring and tidal predictions inform the assessment.

The warning is not a blanket travel ban. It signals that high coastal water may affect shoreline areas and port activity, so travellers heading to Flores, divers and vessel operators should monitor local conditions before travelling or going to sea.

BMKG lists the affected East Nusa Tenggara areas as the coasts of Sumba, Flores–Alor, Timor–Rote and Sabu–Raijua. A regional report says residents, fishers and port users should increase vigilance and follow BMKG’s maritime-weather updates.

Why it matters to Flores travellers

Visitors using beaches, waterfront roads or ports may encounter temporarily higher water levels during the warning window. No specific water height, closure, cancellation or timetable for individual ports is stated, so travellers should treat local conditions as changeable rather than assume that all activities are suspended.

The warning applies to a wider coastal zone than Flores alone. It covers four listed coastal areas in East Nusa Tenggara, including the Flores–Alor coastline.

BMKG advises people to remain alert to the effects of maximum tides and to keep checking maritime-weather information. The warning period ends on 11 November 2026, while the new-moon phase identified by BMKG falls on 9 November 2026.
