Is your island resort open on your dates?

To check whether an island resort is open on your dates, ask for its opening and closing dates in writing and put your own dates beside them. Also ask what happens if the boat cannot sail. No public source gives exact closing dates, and they vary by resort and year.

This page gives you five steps and a message to send. The wider background is in our northeast monsoon guide for island travellers.

What does our research say about the monsoon on each island?

Island	What our research says
Redang	The northeast monsoon, roughly October to March, closes most resorts and restricts ferries, with November to February the wettest [1]
Perhentian	Heavy monsoon from November to February, with most islands essentially closed to tourists [2]
Tioman	Rainfall peaks from November to January, many resorts close, exact months unknown [3]
Lang Tengah	A public boat from Merang runs on a different timetable from April to August than from September to March, fare undated [4]

Treat every row as a broad pattern. None of them is a closing date.

What are the five steps?

1. Know the pattern for your island, using the table above and the island’s season guide.
2. Send the resort a written question about its dates, with yours included.
3. Ask what happens to your booking if the boat cannot sail.
4. Check sea warnings close to your date.
5. Keep every reply with your confirmation.

The reason for step four is that a resort can be open while the sea is not. Travellers check strong-wind and rough-sea warnings at the MetMalaysia site and the myCuaca app, and warnings are updated about every three hours ^[6]. Our guide on sea warnings and boat operations explains how they connect.

What about this year’s monsoon start?

MetMalaysia announced the 2025/26 northeast monsoon to begin on 13 November 2025 and to run to March 2026. We found no 2026/27 date, and it announces only days ahead ^[5]. So any date you see today for next season is an estimate.

That is another reason to get the resort’s own dates in writing, and to leave room in your plans for a change.

What message can you send?

Copy this and fill in your details:

• Our dates are [arrival] to [departure], for [number] guests.
• Are you open on those dates? Please confirm in writing.
• What are your closing and reopening dates this year?
• If the boat cannot sail on our arrival or departure day, what do you offer?
• What is refunded, rescheduled or credited if you cancel?

Ask for a reply that can be saved. A voice note or a verbal yes is hard to rely on later. See our guide on what details to send for an accurate quotation.

What if the dates are close to the edge?

Dates near the start or end of the monsoon carry the most risk. A resort may open late or close early depending on the sea, and a boat can be cancelled on the day.

Choose dates well inside the open period if you can. If you must go near the edge, book changeable flights, ask about a written fallback, and read our guide on best months for east-coast islands and the shoulder-season risks.

A better fit if…

Redang, Perhentian or Tioman in the open months may be a better fit if your dates are fixed by school holidays and you want the fewest surprises.

A west-coast island may be a better fit if your only free dates fall in the monsoon. See our guide to a west-coast island when the east coast is closed.

A flexible plan may be a better fit if you cannot get written dates in time. Wait for the reply before you commit to anything non-refundable.
