The Meteorology, Climatology, and Geophysics Agency (BMKG) has issued a maritime safety warning for several Indonesian waters, advising the public to remain vigilant as waves are expected to reach heights of up to 4 meters. This advisory remains in effect from May 30 through June 2.
Shipping Safety and Vessel Limits
BMKG Director of Maritime Meteorology Eko Prasetyo emphasized that maritime transport operators, ship captains, and traditional fishermen must strictly observe vessel safety thresholds during this window. These limits vary significantly based on the type of craft and current weather conditions.
Fishing boats face vulnerability when operating in winds exceeding 15 knots and waves higher than 1.25 meters. Similarly, barges are at high risk if wind speeds surpass 16 knots or wave heights exceed 1.5 meters. For ferry operations, safety is maintained only when wind speeds stay below 21 knots and wave heights do not exceed 2.5 meters. Large vessels, including cargo ships and cruise liners, are urged to exercise caution if wind speeds exceed 27 knots and waves rise above 4 meters.
Affected Regions
The highest-risk zones, projected to experience waves between 2.5 and 4 meters, include the North Natuna Sea, the northern Malacca Strait, and the Indian Ocean west of Aceh, with winds expected to reach 25 knots. Moderate waves of 1.25–2.5 meters are forecast for a wide range of areas, including the Indian Ocean south of Java to East Nusa Tenggara, the northern Makassar Strait, the Sulawesi Sea, the Banda Sea, and the Arafura Sea.
Future Outlook
Given the current forecast, shipping schedules could face disruptions or delays as captains navigate these high-wave conditions. Should weather patterns intensify beyond the current projections, authorities may extend these safety advisories to ensure the continued protection of maritime transit and local fishing communities.
