BMKG Warns of 2.5-Metre Waves South of Bali on Nov. 10

Denpasar — Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) forecast cloudy conditions across Bali on Tuesday, Nov. 10, 2026, with temperatures ranging from 19 to 33 degrees Celsius. Waves of up to 2.5 metres were forecast in the waters south of Bali.

The warning applies to maritime conditions rather than a general closure. BMKG said the waves could pose a risk to ferry vessels when winds reach 21 knots and wave heights reach 2.5 metres. For fishermen, the stated risk threshold is 15 knots of wind and waves measuring 1.25 metres.

Why the 2.5-metre forecast matters to Bali travellers

For foreign visitors and residents using ferries or smaller boats, the forecast signals potentially difficult sea conditions south of the island. The reported thresholds describe when the conditions become hazardous for particular vessel types; they do not, by themselves, announce that ferry services have been suspended.

BMKG's early-warning information covered the period from 8 a.m. WITA on Nov. 10 to 8 a.m. WITA on Nov. 11. No Bali regency or city was listed as facing a warning for moderate to extreme rain during that period. Winds were forecast from the southeast to the southwest at 4 to 30 kilometres per hour.

Separate reporting on the same BMKG warning described wave heights of 2.5 to 4 metres in the waters south of Bali and the southern Lombok Strait from Nov. 7 through Nov. 10. The Bali-specific forecast for Nov. 10 reported a maximum of 2.5 metres in the waters south of Bali.
