BMKG Warns of Four-Metre Waves in Southern Lombok Strait

Denpasar — A warning from the Meteorology, Climatology and Geophysics Agency (BMKG) said waves in the southern Lombok Strait could reach 2,5–4 metres from Nov. 6 through Nov. 9, 2026. The warning also covered waters south of Bali and urged coastal communities and maritime operators to monitor conditions.

The alert applies to a period when stronger winds and higher waves could affect marine safety. BMKG-linked reporting identified risks for fishing boats, barges and ferries when specified wind and wave thresholds are reached. It did not state that ferry services had been suspended or that ports were closed.

Why the Lombok Strait warning matters to visitors

The southern Lombok Strait is used by vessels moving between Bali and Lombok, as well as by fishing and other maritime activities. For foreign visitors, the practical implication is that crossings and boat excursions could face more difficult sea conditions during the warning period, while the reports do not establish a blanket cancellation of services.

NusaBali reported that waves of 2,5–4 metres were expected particularly in the southern waters of Bali and the southern Lombok Strait. It also said waves of 1,25–2,5 metres were possible in the northern Lombok Strait, Badung Strait and southern Bali Strait.

IDN Times separately reported a BMKG Denpasar warning for 2,5–4-metre waves in the southern waters of Bali and southern Lombok Strait from Nov. 7 through Nov. 10, 2026. That report said fishing boats faced risk at wind speeds of 15 knots and waves of 1,25 metres, while ferries faced risk at 21 knots and waves of 2,5 metres.

The reports said conditions should be monitored through official maritime-weather updates. No later operational decision by a ferry operator or port authority was stated.
