Standfirst: When the habagat picks up, the question in every Dumaguete group chat is the same: are the boats running? The answer is decided by three different bodies, in a fixed order — and knowing which one to check saves you a wasted trip to the port.

Nobody at the pier decides this
The most common misunderstanding is that the shipping line cancels your trip. Usually it does not decide first — it responds.
The sequence runs like this:
1. PAGASA issues the warning. The state weather bureau issues a Gale Warning when seas become hazardous, most often during the southwest monsoon — the habagat — or when a storm is enhancing it. The Gale Warning is a statement about sea conditions, not an order.
2. The Philippine Coast Guard decides who sails. The PCG enforces the no-sail rule. Under Memorandum Circular No. 03-01, small craft operations are suspended during adverse weather, and PCG directives routinely prohibit all motorboats and vessels of 15 gross tons and below from sailing. This is why a small fastcraft can be grounded on a day when a larger vessel still sails — it is a size threshold, not a judgment call about your particular route.
3. Shipping lines may cancel on their own. Separately from any PCG prohibition, an operator may cancel a voyage under the terms of its Certificate of Public Convenience issued by MARINA. A line can therefore cancel when the Coast Guard has not prohibited sailing at all.
Worth knowing: the Philippine Ports Authority does not cancel trips. The PPA has stated plainly that it does not cancel voyages directly; shutdowns follow from PCG prohibitions and from operators’ own decisions.
What this means when you are deciding whether to travel
A Gale Warning is not a cancellation. It is the trigger that makes one likely. If you see a Gale Warning covering the Bohol Sea or the Negros seaboard, expect small craft to be held first.
Vessel size is the best predictor. On the Dumaguete–Siquijor run this is a practical distinction, not a technicality: OceanJet runs fastcraft for foot passengers, while Aleson Shipping and Montenegro Lines run RoRo vessels that carry vehicles. HS Star Marine’s Anika Star and Super Shuttle Ferry also serve the route, between them giving well over a dozen crossings a day.
A suspension aimed at small craft reaches the fastcraft first. If you can move your booking to a RoRo, you are more likely to sail.
The Sibulan–Liloan crossing to southern Cebu is a different case again: a short RoRo hop of roughly 20 minutes across the Tañon Strait, and the usual bus-and-ferry route to Cebu City.
The line knows before the terminal does. Operators post cancellations on their own channels first, and the announcement at the pier is usually the last step, not the first.
Where to check, in order
- PAGASA’s marine forecast and Gale Warning bulletins — whether hazardous seas have been declared at all.
- Coast Guard Station Negros Oriental — the unit with jurisdiction here. It has suspended voyages across all ports in the province during storm conditions, so its directive covers Dumaguete and Sibulan together rather than port by port.
- Your shipping line’s own page — the cancellation itself. For this route that means OceanJet, Aleson Shipping, Montenegro Lines, HS Star Marine or Super Shuttle Ferry, depending on your booking.
If your trip is cancelled
Cancellation for weather is a safety decision, not a service failure.
Ask specifically whether the trip was cancelled under a Coast Guard prohibition or by the line’s own decision — the two are different, and the answer is worth having when you ask about rebooking.
We are not stating rebooking or refund entitlements here, because they are set per operator in its own conditions of carriage and we have not verified them for each line on this route. Ask the operator directly and get the answer in writing.
