Jakarta –
Meteorology, Climatology and Geophysics Council (BMKG extension) issued an early warning high wave which has potential in a number of Indonesian waters on 28-29 December 2022. BMKG revealed the potential for high waves reaching as high as 6 metres.
BMKG explained that the wind pattern in the northern part of Indonesia is predominantly west-north with wind speeds ranging from 8-20 knots, while in the southern part of Indonesia the dominant movement is southwest-northwest. with wind speeds ranging from 5 -30 knots.
“The highest wind speeds were observed in the North Natuna Sea, Java Sea, South Java waters, Flores Sea, Banda Sea, Sermata-Kep Islands waters. Tanimbar and the Sea of Arafuru,” wrote the BMKG’s Legal and Organizational Department. Relations Division in a statement, Tuesday (12/27/2022).
This condition causes an opportunity for increased wave heights of up to 1.25-2.5 meters in the waters west of Aceh-Kep. Mentawai, Western Indian Ocean Aceh-Kep. Mentawai, Kep. Anambas-Kep. Natuna, Sea of Natuna, waters of Kep. Bintan-Kep. Lingga, Karimata Strait, Bangka Belitung waters, Gelasa Strait, Lampung Bay and the northern part of the Sunda Strait.
Then in the West Java Sea, Northern waters of West Java, Southern waters of Kalimantan, Western waters of South Sulawesi, Kep. Sabalana-Kep. Selayar, Bali Sea-Sumbawa Sea, North Lombok Strait, North Sumbawa-Flores Waters, South Bone Bay, Baubau-Kep Waters. Wakatobi, South Sumba Island, Sawu Sea, Ombai Strait, West Sumba Strait, South Sape Strait and Kupang-P waters. Route.

Seram, northern waters of Kep. Kai Kep. Aru, Fakfak-Kaimana-Agats-Yos Sudarso waters, Northwest Papua-Papua waters, North Pacific Ocean Papua-West Papua.
Waves with heights of 2.5 to 4.0 meters are likely to occur in the North Natuna Sea, Bengkulu-West Lampung waters, West Bengkulu-Lampung Indian Ocean, West Sunda Strait and southern waters of Banten-Sumbawa, Bali-Lombok-Strait Southern part of Alas, southern Indian Ocean East Java-NTT, Central and East Java Sea, northern waters of Central Java and East Java, southern part of Strait of Makassar, Flores Sea and Banda Sea, Kep waters. Sermata-Kep. Tanimbar, southern waters of Kep. Kai Kep. Aru, western Arafuru Sea, northern waters of Kep. Talaud, Halmahera North Pacific Ocean.
Meanwhile, very high waves that can reach 4-6 meters have a chance to occur in the southern Indian Ocean of Banten-Central Java and in the central and eastern parts of the Arafuru Sea.
For this reason it is necessary to pay attention to the high risks for navigational safety such as fishing vessels (wind speed greater than 15 knots and wave height greater than 1.25 meters), barges (wind speed greater than 16 knots and wave height greater than 1.5 meters), ferries (wind speed greater than 21 knots and wave height greater than 2.5 meters), large vessels such as cargo ships/cruise ships (wind speed greater than 27 knots and wave height waves greater than 4.0 meters).
“We are asking people who live and do business on the coast around areas where high waves are likely to occur to remain vigilant,” the BMKG added.
