BMKG: Indonesia's rainy season peaks from December to February
BMKG says the rainy season started 20-30 days later than usual, keeping flood and landslide risks elevated.
BMKG forecasts that the peak of the rainy season in most parts of Indonesia will last three months, from December 2026 to February 2027. BMKG chief Teuku Faisal Fathani said this year's rainy season started about 20 to 30 days later than normal, although the overall character of the rain remains in the normal category. BMKG said the conditions still warrant caution because the shorter rainy period could still bring extreme rainfall that may trigger floods and landslides. The warning came after a limited meeting on natural disaster preparedness with President Prabowo Subianto at Istana Negara, Jakarta. In Nusa Tenggara Barat, BMKG also forecasts rains will spread across Lombok and Sumbawa on 11-20 November.
