eadly floods triggered by unseasonable heavy rains have swept across Indonesia during what should be the peak of the dry season, prompting experts to link the extreme weather to climate change, with the meteorology agency warning that intense rainfall could persist until October.
Over the weekend, the National Disaster Mitigation Agency (BNPB) recorded 21 hydrometeorological disasters nationwide, including floods and landslides, with 11 incidents concentrated in Greater Jakarta. As of Monday, at least three people had died, nearly 10,000 displaced, over 2,300 houses submerged, and a dozen severely damaged.
The continuous heavy rain in July, typically Indonesia’s dry season, has baffled authorities and raised concerns over underlying causes.
In March, the Meteorology, Climatology and Geophysics Agency (BMKG) predicted a full transition into the dry season by April to June, describing it as a “wet dry season”. However, the recent disasters have prompted the agency to revise its outlook.
“Contrary to our March forecast, [...] only 30 percent of seasonal zones have entered the dry season. Normally, around 64 percent would have been dry by the end of June,” BMKG head Dwikorita Karnawati said in a statement on Monday.

Dwikorita attributed the rainfall anomaly this year to a weak Australian monsoon, which usually brings about a dry season in Indonesia. This weakness coincides with unusually warm sea surface temperatures south of the country, triggering the heavy rains.
