Questions and Answers

Diving FAQs

What time of year is Thailand's diving season?

November to April marks the tourist high season and the best time to come is from February to April regardless of whether you are diving or not. The weather is at its best with calm seas and, as there are fewer tourists, accommodation can be cheaper. The Similan Island dive sites are not so crowded, and it is the season when you are more likely to encounter a whale shark or manta ray on your Phuket liveaboard diving trip.

For visiting Phuket, Krabi, Phi Phi Islands and Khao Lak, November to April is the best time. However March to September is the best time of year to dive the island of Koh Samui in the Gulf of Thailand. So it is always a good time of year to scuba dive in Thailand. Find more details on the seasons in our Thailand dive sites section.

Are there strong currents at sea?

Some of the dive sites in Thailand do have strong currents but this can depend on the time of year, time of day and the dive site itself. More details are available in our dive sites section. You will be advised by your dive guide in the pre-dive briefings but you will rarely have to swim against a strong current.

Is the scuba diving in Phuket good or do I need to go further afield?

Although there are couple of nice dive spots not far off Phuket's shores, the best dive sites are to be found just an hour or two's boat ride away. Most people take a scuba diving day trip to such sites as Kingcruiser Wreck, the Racha Islands, Shark Point and the Phi Phi Islands.

There is plenty of great local diving to keep you busy for a week or so but if you want to experience the best diving Thailand has to offer then you really should join a liveaboard cruise to the Similan Islands or beyond into Burma/Myanmar.

What about diving in Koh Samui?

The Gulf of Thailand's popular Koh Samui is the largest island and boasts plenty of good quality resort hotels. The diving is not as spectacular as Phuket or the Similan Islands, but there are several good and well-known dive sites. This is a good place for a diving day trip during Phuket's diving low season. For more details about getting there and what to do, see our Koh Samui tourist section.

Liveaboard FAQs

What is a liveaboard cruise?

A Thailand liveaboard cruise is a diving vacation where you eat and sleep on the boat as it takes you to the different dive sites. All the diving facilities and living accommodation are housed on the boat. As the vessel stays at sea for the duration of the trip, remote dive sites can be explored and there is a greater opportunity to dive excellent sites that are not within reach on a normal daytrip boat.

Thai liveaboard destinations are the Similan Islands, the Surin Islands, Hin Daeng - Hin Muang, as well as the Mergui Archipelago (Burma).

How many dives can I do each day?

Most boats offer up to 4 dives a day with about 3 hours between dives to relax. The first dive is often early in the morning around 7 am and the last at sunset or slightly later for a night dive.

Can I dive on my own on a Thailand liveaboard?

You will be expected to dive with a buddy on your liveaboard trip as the boats are recreational diving cruise charters, so follow the recreational scuba diving guidelines. You can dive without a guide if you prefer as long as you dive to a maximum depth of 40m, observe safe diving limits and have all the necessary equipment to dive unassisted, i.e. dive computer or timing device, submersible marker buoy and compass.

What type of tanks and valves are on the boats?

Most Thailand liveaboard boats provide 12 litre aluminium tanks with yoke or A-clamp international valves. If you have a DIN regulator you can either bring an adaptor with you or rent or buy one on arrival. It is possible to rent 10 and 15 litre tanks by booking in advance. Some boats have enriched air nitrox on board too. You can see the details of each boat page.

What kind of food is served?

The food selection and standard is usually excellent on Thailand scuba diving cruises. Have a look at 'Food' information of your boat for details of the type of food served on your trip.

Can I order vegetarian food?

Yes of course. Vegan as well. Please let us know your requirements when you make your booking.

What do I need to bring on board?

You need to bring all your personal diving gear except tanks, weights and your weight belts, a bathing suit, towel and toiletries. Warm weather clothes are fine such as shorts and T-shirts but you may want something a little warmer for breezy evenings. Sun protection is also a good idea.

Will I get sea sick?

If you suffer from sea sickness then it's a good idea to take your liveaboard cruise from February to April when the sea is at its calmest. All the charter boats stock anti sea sickness medication for your use too.
At night the boats tie up to mooring points at the islands visited on the trip. These mooring points are found in the islands' bays, sheltered from the open seas.

Is Malaria a problem?

There is no Malaria at any of the Thailand liveaboard destinations.

Can a non-diver go on a liveaboard?

Yes, non-divers and snorkellers can enjoy a liveaboard cruise although they are really designed for divers. Many of the dive sites are suitable for snorkelling especially in the Similans.

The price for a non-diver is often 10% less which sounds like a small discount but you are taking a place that would otherwise be available to a diver. Please review the 'More Trip Details' on the boat page for exact non-diver price for your cruise.

I'm a single traveller, will I need to share a cabin?

Generally you are expected to share on a Similan liveaboard boat as sleeping space is at a premium. Occasionally if the boat is not full and there are an odd number of passengers you might be able to have your own cabin. If you insist on staying alone in a cabin then you will need to pay a single supplement. These vary from one liveaboard to the next from 50% to 90% of the published price. Always check with us for the best deal if you are travelling alone.

Can I explore the beaches at the islands?

You have several hours of surface interval time between dives when you are free to do what you want. If the boat is not moving to another dive site you can explore the island. Please advise the boat's tour leader before disembarking.

Will I see sharks?

Yes definitely! The most common sharks in the Similan Islands are leopard sharks and whitetip reef sharks. Silvertip reef sharks and nurse sharks are more commonly seen on Burma liveaboard cruises. Whale sharks have been sighted fairly often some years so you may be lucky!

Manta rays encounters have been quite common in recent years, and you are practically guaranteed of seeing blue-spotted sting rays, marble rays and fantail rays.

General FAQs

Will I need a visa to visit Thailand?

Visitors from most Asian and Western countries, including those from Europe, North America, Australia, New Zealand, and South Africa, are granted a visa waiver on arrival. This allows for a 60-day stay when entering by air or a 30-day stay when arriving by land or sea. The permit can be extended by an additional 30 days for a fee at any immigration office in major cities and tourist destinations. However, travellers from some other nations must obtain a tourist visa in advance from a Thai embassy or consulate. For the latest regulations and requirements, visit the: Thailand Immigration Bureau's website.

Do people speak English there?

In Thailand's main tourist destinations English is widely spoken and understood and it is possible to have a fantastic holiday without worrying about communicating.

However if you speak even just a few words it can go a long way to better understanding the Thai culture and is really appreciated by the locals. Get yourself a phrase book and learn a few basic words and sentences - it could save you some money on your purchases too!
