Indonesia on High Alert: BMKG Warns of Prolonged Dry Season and El Niño Risks in 2026
Indonesia is bracing for a challenging climatic year as the Meteorology, Climatology, and Geophysics Agency (BMKG) warns of a dry season that is expected to be drier and longer than normal. With the potential return of the El Niño climate pattern in the second half of 2026, authorities are intensifying efforts to safeguard food security and prevent catastrophic wildfires.
The Looming Threat of El Niño
The BMKG has indicated that global climate patterns are shifting. While the El Niño–Southern Oscillation (ENSO) is currently in a neutral phase, there is a significant probability that a weak to moderate El Niño will emerge mid-year. According to ANTARA News, the probability of this shift is estimated between 50% and 80%.
It’s important to distinguish between a standard drought and El Niño. BMKG head Teuku Faisal Fathani explains that while drought is a regular part of the climatological cycle, the coincidence of El Niño significantly reduces rainfall, making conditions much drier than usual. This synergy increases the risk of severe water shortages and prolonged dry spells.
Early Warning Signs and Current Conditions
The transition toward a drier climate is already evident. By the end of March 2026, the BMKG noted that 7% of Indonesia’s Seasonal Zones (ZOM) had already entered the dry season. The agency emphasizes that the 2026 dry season could arrive earlier and last longer than typical patterns.
The impact is already visible in the form of increased fire risks. As of early April 2026, the number of hotspots in Indonesia reached 1,601, a figure higher than the same period in previous years, according to reports from ANTARA News.
Critical Impacts: Food Security and Public Safety
The prolonged dry season poses a direct threat to Indonesia’s agriculture sector, which remains highly dependent on consistent water supplies. A lack of rainfall could jeopardize food security across the archipelago.
Beyond agriculture, the government is focusing on two primary areas of concern:
- Wildfire Prevention: Increased monitoring of land and forest fires to prevent the widespread haze often associated with El Niño years.
- Early Warning Systems: On April 13, 2026, during a meeting with Commission V of the DPR RI, the BMKG discussed strengthening the accuracy and speed of real-time early warning systems for extreme weather, following evaluations from the 2026 Lebaran holiday period, as reported by the BMKG official portal.
Key Takeaways for 2026
- Probability: 50% to 83% chance of a weak to moderate El Niño emerging in the second half of 2026.
- Climate Outlook: The dry season is expected to be drier and longer than the 30-year norm.
- Immediate Risks: Increased hotspot activity (1,601 recorded in early April) and threats to agricultural productivity.
- Government Action: Focus on real-time weather alerts and forest fire mitigation.
Frequently Asked Questions
What is the difference between a drought and El Niño?
A drought is a natural climatological cycle of water shortage. El Niño is a global climate pattern involving sea surface temperature changes in the Pacific. When they coincide, rainfall is significantly reduced, intensifying the drought conditions.
When is El Niño expected to impact Indonesia in 2026?
The BMKG expects the potential development of El Niño to occur in the second half of 2026.
How is the government responding to these risks?
Authorities are implementing measures to tackle land and forest fires, safeguarding food supplies, and improving the speed of extreme weather warnings through the BMKG.
