Night Diving in Costa Rica

Have you ever wondered what it’s like to be underwater during night? There’s only one way to find out: Let’s go night diving.

Some people have said that the only difference between diving at night and a day dive at the very same site is just the absence of light. While this may partly be true, you should know by now that the reef transforms into a different world once the sun sets down. Our reef system is nocturnal within itself. Your favorite coral may not totally look the same at night where coral polyps goes out and extends its so called tentacles to feed. Some species of fish are more active during night compared during the day, like the smaller types of sharks for example. On the other hand, cracks and crevices may be empty during day time but can be filled with day-time fishes seeking refuge for the night.

Sparkling Lights Underwater

No, I am not talking about stars or any light reflected from the surface. I am referring to the miniature bright light created when there is water motion. This is called bioluminescence courtesy from the primary producers of our oceans, the plankton. While you will be using an underwater torch or flashlight, you have the option to turn it off for a second and make a wave using your hands and you will be amazed by the lights generated from the movement of water. Well, this can be observed in almost any diving site in the world, but this is more pronounced in Costa Rica as the waters are known to be plankton-rich. Just a reminder: don’t forget to turn on back your lights to go with your dive plan and proceed with your underwater nocturnal adventure.

Becoming a Certified Night Diver

Yes, we know you’re excited to experience what we just mentioned. But wait, night diving is not just setting up your gear and provide yourselves with a torch. Night diving requires special training and can only be done through a certification course.

You have two options if you want to immerse yourself in this totally different diving experience. First, you can sign-up for the Advanced Open Water Diver Certification course where one of the advanced skills taught is night diving. Second, if you want to specialize and focus your skills and learning, you can enroll for the Night Diver Specialty Course. Nonetheless, regardless of what option you choose, the requirement is that you should be at least 15 years old and a certified Open Water Diver.

During the course, you will be taught how to properly use the underwater torch or flashlight and learn to focus your sight to the direction of where the light is pointing. You will also master your buoyancy control by feel or instinct as the absence of light gives you this feeling of having a no reference point. Another thing that is being pointed out during the course is communication skills using your torch and navigating to your entry and exit points.

Reminder: Do not directly point your torch to the eyes of your buddy.

At the end of the day, allow us to share our personal experience, recommendation and benefits we got from night diving. First, do not be confused with direction. Some divers have been confused and descended down thinking that they are going up. With this, our advice is ALWAYS LOOK AT THE BUBBLES as it is always going up and from there, you will gain your direction and orientation with reference to the surface. Second, if disorientation really sets in, do not forget to do this: RELAX, STOP, THINK THEN ACT. And we tell you, the next time you do a day dive, it will be much easier as you have already exposed yourself to this one of a kind diving experience.
