Malaysia boasts some of its greatest treasures in islands scattered across two distinctly different coastlines. Before packing your bags, two questions inevitably arise: how do you reach them by ferry, and when should you travel to enjoy favourable weather? This guide has all the answers.

Two coasts, two different worlds

The Malaysian peninsula is bordered to the west by the Andaman Sea and to the east by the South China Sea. This geography is crucial to understand, as it directly determines rainy seasons, island closure periods, and available maritime connections.

To the east, you'll find Perhentian, Redang, and Tioman. To the west, Langkawi and Penang. Sipadan, meanwhile, is located in East Malaysia, on the island of Bornéo.

Weather, island by island

Langkawi (west coast)

Langkawi enjoys favourable weather year-round. High season runs from November to April, with generous sunshine and calm seas. The rainy season, from June to October, remains generally manageable. Showers are often brief, though September and October tend to be the most humid.

Penang (west coast)

Penang follows a similar rhythm to Langkawi. The best period is December to February, with drier and more pleasant conditions. September and October are the wettest months, but rain typically falls in the evening and won't necessarily disrupt your stay.

Perhentian and Redang (east coast)

Most tourist facilities close from November to February inclusive, due to the northeast monsoon. Waves can exceed 3 metres and maritime services are suspended. High season runs from March to October, peaking between June and August.

Tioman (east coast)

Tioman follows the same calendar as Perhentian and Redang. Most accommodation and dive operators close between November and late February. The best time to visit is April to August, when waters are most transparent.

Sipadan (Bornéo)

Sipadan is accessible year-round, though conditions can be more unstable between January and March, with sometimes rough seas and reduced underwater visibility. The ideal diving season runs from April to December. Note that access to Sipadan requires a daily permit limited to 176 divers. Book several months in advance.

Reaching the islands by ferry

Langkawi

From Kuala Perlis (45 mins) or Kuala Kedah (1h15), speedboat ferries operate to Langkawi. The main port is Kuah Jetty. Services from Penang exist but remain limited or variable depending on the season. Flying remains today's most reliable option to link these two destinations.

Penang

Penang is connected to the mainland by ferry from Butterworth, accessible by train or bus from Kuala Lumpur. The crossing takes just 15 minutes and ferries depart approximately every 20 minutes. This is one of Malaysia's simplest and cheapest maritime links.

Penang is also connected by a 13.5 km road bridge if you're travelling by car or long-distance bus.

Perhentian

The essential departure point is Kuala Besut jetty in Terengganu State. Speedboats reach the islands in 30 to 45 minutes. There is no conventional ferry service on this route. The journey is economical—expect around 35 to 40 RM per person.

Redang

Boats to Redang depart from Shahbandar Jetty in Merang or from Shahbandar in Kuala Terengganu, depending on your accommodation. The crossing takes approximately 45 minutes to 1 hour. Most resorts include boat transfers in their packages. Verify before booking.

Tioman

Tioman is reached from Mersing port in Johor State. The speedboat journey takes roughly 1h30 to 2 hours depending on sea conditions. You can also opt for Teluk Gading jetty (Tanjung Gemok), which is less prone to tide-related delays.

Sipadan

Sipadan is not directly accessible from the peninsula. You must first fly to Tawau in East Malaysia (Sabah), then reach Semporna by taxi (approximately 1 hour). From Semporna, speedboats serve nearby islands such as Mabul and Kapalai, from which diving expeditions to Sipadan depart. No accommodation is permitted on Sipadan itself.

Common mistakes to avoid

• Booking a stay on east coast islands in December or January without realizing most facilities are closed
• Arriving in Mersing without checking boat schedules (In low season, departures are reduced.)
• Failing to reserve your Sipadan permit in advance and finding yourself stranded on Mabul unable to dive
• Confusing the two departure jetties for Redang depending on which resort you've chosen
