Indonesia braces for El Niño‑driven drought, water shortages and wave warnings
Indonesia is confronting a strong El Niño that has pushed the seasonal dry spell into an extended drought. The BMKG reported a Nino 3.4 index of +2.26 °C and warned that the phenomenon could last nine to twelve months, raising the risk of extreme heat, forest fires and water scarcity across the archipelago.
A BMKG wave‑height warning announced that seas around Ambon and nearby islands could see waves of 1.25‑2.5 m from 1 – 4 August 2026. Simultaneously, the agency placed 17 districts in West Nusa Tenggara (NTB) on a drought‑alert, noting some stations in Bima have gone 74 days without rain.
Government agencies responded with emergency water supplies: Kemenkum NTB delivered four tanks holding 20,000 L and three additional tanks to the village of Tibu Lilin in Lombok Barat; the local military unit Kodim 0730/Gunungkidul readied a water‑tank truck and distributed three tanks to drought‑hit villages; and the Ministry of Public Works, led by Dody Hanggodo, activated more than 10,000 boreholes and is optimizing dams and reservoirs to secure water for agriculture and households.
The United Nations Secretary‑General Antonio Guterres also warned that the strengthening El Niño will exacerbate global climate impacts, underscoring the broader significance of Indonesia’s current water‑crisis response.
