BMKG: Beware of Tidal Floods and Heavy Rain During Eid 2026 in West Java
Bandung (ANTARA) - The Meteorology, Climatology, and Geophysics Agency (BMKG) has reminded holidaymakers and the general public to be wary of the potential for coastal flooding up to heavy rain predicted to occur during the peak of the Eid al-Fitr 1447 Hijriah holiday period in March 2026.
The Head of the Class I Bandung Geophysics Station, Teguh Rahayu, in Bandung on Thursday, revealed that the threat of coastal flooding is predicted to emerge on 19 March and 22 March 2026 due to the new moon phenomenon and the closest distance between Earth and the Moon (perigee).
In addition to tidal floods, holidaymakers in West Java are asked to schedule their journeys from morning to afternoon to avoid heavy rain that predominantly falls in the afternoon and evening.
“Weather modification operations are carried out situationally and based on needs to suppress rainfall intensity in areas with potential for hydrometeorological disasters,” said Rahayu.
BMKG has mapped areas with high rainfall during the Eid period, including Majalengka, southwestern Kuningan, parts of Sumedang, and southeastern Subang.
Meanwhile, sea wave heights in West Java waters are estimated to reach 1.25 to 2.5 metres.
Landslide Risk
In line with BMKG, the Head of the Center for Volcanology and Geological Hazard Mitigation (PVMBG), Hadi Wijaya, emphasised that the ongoing rainy season increases the risk of landslides on steep slopes and weathered volcanic rocks.
PVMBG has issued special warnings for holidaymakers passing through the Puncak Route, Cibadak-Sukabumi Main Road, southern Garut route, as well as the Lembang-Maribaya-Subang tourist route.
These routes are assessed to have high vulnerability to landslides, especially when rainfall intensity increases.
The public is urged to recognise early signs of landslides such as cracks appearing on slopes, small rockfalls, and trees beginning to tilt.
Holidaymakers are advised to stick to main routes, avoid stopping under cliffs during rain, and comply with instructions from on-site officials if route diversions occur.
