BMKG: Fishermen and Ferry Operators Urged to Beware Shipping Risks

Jakarta (ANTARA) - The Meteorology, Climatology, and Geophysics Agency (BMKG) has urged traditional fishermen and ferry operators to heighten their vigilance against shipping safety risks posed by the threat of high waves in several Indonesian waters from 8 to 11 September 2026.

Agie Wandala Putra, Acting Director of Maritime Meteorology at BMKG, affirmed in Jakarta on Tuesday that sea wave conditions reaching up to four metres could endanger sea transport modes ranging from small to large scale.

“People carrying out activities at sea need to pay attention to safe safety thresholds. Fishermen with small boats face high risk if wind speeds exceed 15 knots and wave heights rise above 1.25 metres,” he said.

The extreme weather conditions in these waters are triggered by strong winds of up to 25 knots observed in the Indian Ocean west of the Nias Islands to Lampung, the Indian Ocean south of Banten, the Java Sea, the southern part of the Makassar Strait, and the Maluku Sea.

BMKG projects that high waves of 2.5 to 4.0 metres are at risk of striking the entire Indian Ocean south of Java, Bali, West Nusa Tenggara (NTB), and East Nusa Tenggara (NTT), as well as the Indian Ocean west of the Mentawai Islands to Lampung.

Meanwhile, moderate waves of 1.25 to 2.5 metres could potentially occur in the northern part of the Malacca Strait, the Java Sea, the Makassar Strait, the Sumbawa Sea, the Flores Sea, the Banda Sea, the Arafura Sea, and the Pacific Ocean north of Maluku.
