Heavy rain inundates thousands of homes as strong El Niño fails to prevent localized flooding.
Severe flooding has struck parts of Aceh, affecting thousands of residents, damaging infrastructure, and forcing some families to seek temporary shelter. The floods occurred despite El Niño conditions, which are generally associated with reduced rainfall in many parts of Indonesia.
More Than 32,000 Affected in Pidie Jaya
Flooding in Pidie Jaya Regency affected approximately 32,272 people from 8,608 households after heavy rainfall in upstream areas caused rivers to rise on November 8. According to Indonesia’s National Disaster Mitigation Agency (BNPB), 8,608 homes across 43 villages in five districts were inundated, while at least 40 people sought temporary shelter. Agricultural areas were also submerged.
Damaged Embankments Worsen Flooding
Breaches in river embankments worsened the flooding, damaging the local clean-water supply network and disrupting access along the main Banda Aceh–Medan road. As of the afternoon of November 10, several villages remained inundated, although water levels had begun to recede in some locations. Emergency teams were evacuating residents, distributing food assistance, and repairing damaged embankments.
Flash Floods Also Strike Gayo Lues
Aceh’s flooding was not limited to Pidie Jaya. In Gayo Lues, heavy rainfall from November 7 into November 8 caused rivers to overflow and send logs and thick mud into residential areas. 390 people from 126 households were affected, four homes were swept away, and another 111 suffered varying levels of damage. Twenty-six residents temporarily stayed with relatives, while bridges and public facilities were also damaged.
Strong El Niño Does Not Eliminate Heavy Rain
The floods highlight how El Niño does not necessarily prevent episodes of extreme rainfall. Although El Niño is generally associated with drier conditions across much of Indonesia, its effects vary by region and season. Local weather systems and other atmospheric conditions can still produce heavy rainfall and flooding, including in Aceh.
Authorities Urge Continued Preparedness
BNPB said local disaster management agencies were continuing to monitor flood conditions, collect information, and coordinate emergency assistance in affected areas. With flooding continuing in some villages, residents in vulnerable locations should follow official warnings and evacuation instructions issued by local authorities.
The Aceh floods show that a strong El Niño does not remove the risk of sudden heavy rainfall and hydrometeorological disasters. For Indonesians, the events reinforce the need for reliable early warnings, stronger river infrastructure, and local preparedness even during generally drier climate conditions. For Singaporeans, Aceh’s experience provides another example of the increasingly complex weather patterns affecting Southeast Asia and the importance of regional climate monitoring.
