What is UV Night Diving?
We divers are a pretty creative bunch when it comes to naming. You have cave diving which is diving in caves. Wreck diving, which is diving in wrecks. You also have ice diving, which is…wait for it…diving in ice.
So, you can probably guess from the name that UV night diving is diving at night using a UV light. But, why would anyone want to do that? Diving at night is scary enough as it is when you have bright flashlights. Why would you want to go with a less bright UV light?
The short answer is because it’s pretty cool what you can see. The longer answer, because there are tons of fish and coral which chemical compounds in them. These chemical compounds light up in unusual ways when you shine a UV light on them.
Just as you can dive one spot during the daytime and then go back at night to see something different. So too can you go to that same spot the next night with a UV light and see it as an entirely different world.
UV lights are on a spectrum between 10 and 400 nanometers (nm). When you shine these lights on coral and certain types of fish, it causes them to emit light and crazy colors. Or, in more scientific terms, to fluoresce. If you are interested in the technical aspects of what fluorescence is, you can read this.
Marine biologists and researchers have been using this technology for quite a while. Until recently though, the technology was too expensive for recreational divers to use. But, new advancements in the technology of UV lights have completely changed this. Dive centers around the world are beginning to offer UV dives as part of their regular schedule. You can even purchase a UV light for yourself to make your own UV night dives.
Let’s take a look at some of this technology.

Tovatec is a well-regarded manufacturer of dive lights and adventure lights. Their flashlights are known for being durable and built to last.
One of the great things about their lights is that they avoid many of the issues that other dive lights are known to have. Namely, they can hold up at depth. Many lights advertise themselves as being durable. But, once you get a few meters underwater, they start to leak and eventually flood. You won’t have this issue with Tovatec dive lights.

1. Koh Tao, Thailand
Koh Tao is already one of the most popular places in the world for diving. More open water certifications come from this island than anywhere else in the world. So, chances are as a scuba diver you will end up here at some point anyway. Why not add UV night diving to your list of things to do when visiting. There are dozens of shops and schools on the island so you can easily find the school that is perfect for you.
Who to dive with: Normally, we recommend Buddha View Dive Resort when diving in Koh Tao. We’ve had great experiences with them. But, for UV night dives, we recommend Master Divers. They offer UV night dives throughout the year. You must have at least one non-UV night dive prior to booking.

2. Bonaire, Caribbean Sea
Bonaire is a major diving destination and one of the most visited islands of the Dutch Antilles. The island is north of Venezuela in the warm waters of the Caribbean Sea. Bonaire is protected from storms which affect other islands during hurricane season. This makes it a great area for diving year-round.
Like Koh Tao, there are many dive shops around the island so you have a wide selection. One thing that is nice about Bonaire is that many of the best night diving spots are shore dives. So, you can rent a car and visit more than one spot in one night.
Who to dive with: We recommend VIP Diving. They have been around since 2009 and have a great safety record. Their divemasters are well trained and knowledgeable of the best sites around the island. They were also one of the first dive schools on Bonaire to offer UV night dives. Like Master Divers, you need previous night diving experience with a regular light.

3. Huravalhi Island, Maldives
The Maldives is known for some of the most beautiful beaches around the world. It’s world-famous for the bioluminescent plankton you can see certain times of the year.
But, this isn’t the only natural light show. You can also see coral in a new way on a UV night dive. We recommend Huravalhi as they have great beaches and crystal clear waters. There are also some great resorts on this island.
Who to dive with: We recommend Prodivers. They have dive centers all around the Maldives. They are one of the top-ranked dive centers in the country and have great staff. The divemasters at their different locations are knowledgeable about the different dive sites. Overall, they are a great dive center for both UV night diving and regular fun dives.
Some UV Diving Tips
- UV light is harmful to your eyes. So, do not look directly into the light. Also, be cautious when diving to not shine the light into the eyes of anyone else. If you are using blue light with a yellow filter this is less harmful.
- You need to have near-perfect buoyancy when doing a UV night dive. It is important to manage your buoyancy to avoid damaging reefs. This is not a diving activity for brand new divers.
- Try to go on at least three-night dives before doing a UV night dive. Night diving is totally different than daytime diving. There are many potential hazards you must learn to mitigate and contend with. With UV night diving, these hazards can be enhanced due to reduced visibility. It is best to get a feel for diving at night first and then introduce the UV aspect.
