BMKG Predicts the 2026 Dry Season to Begin in April, Starting from Nusa Tenggara

BMKG predicts that a number of regions in Indonesia will enter the dry season starting April 2026. The season will begin in Nusa Tenggara and gradually move to other regions.

‘The early dry season — the majority of Indonesia — is predicted to enter the dry season in April, with 114 monsoon zones, or around 16.3 percent of all zones, out of 699 zones in Indonesia,’ said BMKG head Teuku Faisal Fathani at a press conference at the BMKG office in Jakarta on Wednesday (4 March 2026).

He added that in May 2026 there will be 184 monsoon zones, and in June 2026, 163 zones will enter the dry season.

‘It will start from the Nusa Tenggara region and move westward gradually to the rest of Indonesia,’ he said.

Furthermore, he warned that the duration of the dry season in most regions located within 400 monsoon zones will be longer than normal.

The peak of the dry season is forecast to occur in July 2026 for parts of Sumatra, central and northern Kalimantan, parts of Java, parts of West Nusa Tenggara and East Nusa Tenggara, northern West Sulawesi, western Central Sulawesi, western North Sulawesi, parts of Maluku, Central Papua, and eastern Papua.

The areas experiencing peak dryness in August 2026 are central and southern Sumatra, central to eastern Java, most of Kalimantan, Sulawesi, Bali and Nusa Tenggara, parts of Maluku, North Maluku, and Papua Island.

Meanwhile, BMKG forecasts peak dryness in September 2026 for parts of Lampung, small parts of Java, most of East Nusa Tenggara, northern and eastern Sulawesi, most of North Maluku, parts of Maluku, and small parts of Papua Island.
