Indonesia's 2026 Rainy Season Is Arriving Late: BMKG Spills Why
Indonesia's rainy season is predicted to be delayed and shorter in 2026-2027. The BMKG explains why.
The Meteorology, Climatology, and Geophysics Agency (BMKG) has forecasted that the start of the 2026–2027 rainy season in Indonesia will be delayed due to strong El Nino activity combined with a positive Indian Ocean Dipole (IOD). This climate phenomenon has prolonged dry conditions, causing the rainy season to arrive late and last for a shorter duration.
Head of BMKG, Teuku Faisal Fathani, revealed that the rainy season onset will vary across the archipelago, with different regions experiencing it in November, December, or January 2027. Areas such as Sumatra, Java, Kalimantan, Bali, and various parts of Sulawesi, Maluku, and Papua are forecasted to begin their rainy season in different months.
BMKG predicts that the overall duration of the rainy season will be shorter than average across 482 season zones, but some areas will experience longer rainy seasons, lasting until February 2027.
