Jakarta — Indonesia is bracing for a more intense wet season than usual, with the peak flood risk expected to stretch longer and affect more regions across the archipelago, the Meteorology and Geophysics Agency warned Friday. The wet season, which starts this month, will extend into April 2026, with its worst phases shifted depending on the island group.
The islands of Sumatera and Borneo are projected to enter the peak wet period in November and December, while Java, Sulawesi, Maluku, and Papua are slated to encounter their heaviest rains between January and February 2026. Officials cautioned that some areas might experience extreme rainfall events where the amount that typically falls over a month could occur in just a day.
Recent rains in Bali offer a preview of what may come: heavy rainfall on Tuesday and Wednesday triggered floods in Denpasar and six surrounding regions, claiming 18 lives and displacing more than 500 people. The agency highlighted that the dry season is likely to be shorter than normal this year due to above-average precipitation.
