Ferry and fast-boat cancellations in rough weather

Ferries and fast boats can be delayed or cancelled when seas are rough, and the harbour authority and the operator make that call. Plan for it by leaving a buffer day before any flight home, and by asking your operator what happens if a sailing is cancelled. A cancellation is a safety decision, so the useful question is what the fallback is.

What does a rough-weather cancellation look like?

In a 2018 episode of high waves, fast boats between Bali and Lombok and between Lombok and the Gilis were suspended. The Padang Bai port authority closed its pier, and Lombok port authorities stopped port activity ^[1]. Larger ships needed the harbourmaster’s permission, which was granted in the morning when waves were lower ^[2].

Stranded guests relied on flights, ferries from Bali and chartered fishing vessels ^[2]. That is an older case, so treat it as a pattern, not a prediction.

Who decides, and who can help?

Who	What they decide	What you can ask
Harbourmaster or port authority	Whether the pier or route opens	Nothing directly; follow the operator’s notice
Boat operator	Whether a sailing runs, and how it reschedules	Next sailing, refund, reschedule in writing
Agency	Hotel, driver and onward legs	Whether to switch to ferry, road or flight
Hotel	Late checkout, extra nights	Rate for an extra night
Driver	Pickup times	Whether to hold or move the pickup

How do you reduce the risk?

One boat-travel guide advises avoiding fast boats when swell exceeds 1.5 to 2 metres ^[3]. It suggests travelling in the morning when seas are calmer and checking forecasts such as the national meteorology agency BMKG. It also advises choosing reputable operators that reschedule rather than sail in a storm ^[3].

Short routes, such as Sanur to Nusa Penida, are easier to manage than a long crossing to the Gilis. If you need to reach Lombok, our Bali to Lombok ferry versus flight guide compares the options door to door.

What if your boat route also meets a festival?

Some routes pause during ceremonies. For Nyepi 2026, the Padang Bai to Lembar route was suspended during the silent day ^[4]. Our Nyepi 2027 guide explains what to confirm for next year.

What about Batam and Bintan crossings?

Batam and Bintan trips from Johor or Singapore depend on a ferry too. Rough seas can delay a crossing, so leave time between the ferry and any onward flight. Our Batam ferry arrival and resort transfer guide shows how to place transfers around the sailing.

What should you ask before you pay?

1. What happens if the operator cancels the sailing: refund, reschedule or credit?
2. How is the new sailing time confirmed, and by whom?
3. Is the hotel booking flexible if you arrive a day late?
4. Does travel insurance cover missed connections? Our travel insurance checklist lists what to check.
5. Where is the buffer day in the itinerary?

Keep the answers in writing, and leave one free day before your flight home. If a volcano is also in the news, read our volcano disruption guide too.
