Frequently Asked Questions

Here you will find some frequently asked questions about Lembongan, Penida and Twin Island Dive Lembongan.

Cancellation Policy:

What is Twin Island Dive's cancellation policy?

Twin Island Dive requires a 50% deposit, this guarantees your booking and is non-refundable.

Guest cancellations due to being late or ‘personal preference’ e.g. not wanting to dive in the rain, being too tired or hungover 😊, will not be refunded.
Medical conditions, that result in you not being able to dive, will be assessed based on the circumstance. 


Is there a high and low season in Lembongan?

Yes there is a ‘high and low season’ in Lembongan. The high season runs from June – October and this is normally the dry (cooler) season. The low season runs from November – May and this is the so-called wet (hotter) season.

There is a large rise in tourists during the high season. If you are looking to come to Lembongan during this time, it is best to book your diving, accommodation and transfers in advance.

There is no monsoon during the wet season in Lembongan, but February and March tend to have more rain fall. Normally during this time it rains for a few hours each day.

When is the best time to see the manta rays?

The manta rays can been seen all year round. There is no set time of the year where you have a higher chance to see them. You have about a 70% chance to see the manta rays at the manta dive sites.

The manta dive sites are located on the south coast of Nusa Penida, this side of the island is more exposed to the open sea conditions. During the low season, the wind is a little stronger, which can make the waves bigger. This can restrict our ability to get to the manta dive sites.

When is the best time to see the mola mola?

The mola is a seasonal creature that can only be seen during certain parts of the year. You are more likely to see the mola when the water temperature drops. The colder the water, the better the mola season is.

Molas spend most of their time in deeper, cooler waters. When the top water column cools, the molas are able to come up into shallower water, allowing divers to see them.

The water temperature normally drops during the high season (around July), so the ‘mola season’ is from July – October.

What is the average water temperature?

The water temperature can change quite a bit through the year.

During the low season (November – May), the water is normally warm; averaging around 28° Celsius (82.4° Fahrenheit).

During the high season (June – October), the currents pull cooler water up from the deep, causing the temperature to drop. The temperature can reach as low as 16° Celsius (60.8° Fahrenheit) at some sites.

These cooler currents create thermoclines which can result in large temperature changes during a dive.

The average water temperature during the high season is around 24° Celsius (75.2° Fahrenheit).

What brand of equipment does Twin Island Dive use?

A full set of rental diving equipment is included in our diving prices.

  • Regulators: Apeks AT20. This is a high end recreational scuba diving regulator. Our regulators are serviced annually.
  • BCD: Aqualung wave BCD. This is a simple and easy to use, robust BCD.

I have DIN regulators, do you have DIN tanks or do I need an adapter?

All our tanks have universal tank values. This means that we are able to remove the insert from the tank valve, allowing you to use your DIN regulators on our tanks.

Do I need to complete a medical form before starting a course with Twin Island Dive?

For all courses with Twin Island Dive, you will need to complete a short medical form on site to show that you are fit for diving.

You are able to download a copy of the medical form, from here to check to make sure you are fit for diving.

If you were to answer ‘yes’ to any questions on the medical form, you will need to see a doctor before going in the ocean. This doctors check can be done on Lembongan or before you arrive.

I have been told that there are strong currents at some Penida dive sites, is this true?

It is possible to get some currents around some of the Penida / Lembongan dive sites.

It is these currents that keep the flow of nutrient rich waters high, which help support the coral and fish life.

Dive sites are picked the afternoon before diving, based on the conditions; wind, waves, currents, tides, who is on the boat and what people are hoping to see. This way, we are able to pick the best sites for the day. We also adjust our departure time, so that we are diving at the best tide.

The dive sites that are known for strong currents are only for experienced divers.

Island facilities:

Are there any ATMs on the island?

There are several ATMs on the island.

  • Mandiri ATM, approx. 100m from Twin Island Dive

Are there any money changers (Western Union) on the island?

Is it possible to snorkel from the any of the beaches around Lembongan / Ceningan?

Unfortunately, the best spots for snorkelling are only accessible by boat. Twin Island Dive is able to help organise snorkelling trips for you, if you are accompanying a friend/family member that is scuba diving, but otherwise we recommend Captain Pinky, you can WhatsApp him here.

If you choose to snorkel from the beaches, please note that most beaches have either strong currents or a lot of boat traffic, so it is best to check the conditions before swimming too far out and be aware of your surroundings.
