How does a Dive Go in Sri Lanka?

First of all, it is customary to dive in the morning, so you will have to go to the chosen diving club around 8am/8h30. Remember to book in advance if you can in order to be sure to have an instructor available.

Before diving, the team will ask you your level and what your expectations are. If you have practiced for a long time, they will then ask to do some basic exercises before going under water, as the one to remove and put his mask back in the sea. It will help you to recall the basics of scuba diving.

It is really important to choose a diving club that will listen to you. Diving, whether it is for the first time or not, can be a little scary. We must therefore feel confident, reassured and with professionals. After the initial brief, you will prepare and test the material that will be used. Combination, bottles, mask at the right size, weight for the belt, fins, floater vest, everything will be tried and tested.

After that, you will go to the sea and be ready for moments of underwater magic! Do not hesitate to communicate with your instructor or your “buddy” (your diving partner) and follow the instructions given. You are also advised to be as calm as possible under water, because it will allow you to dive longer! Indeed, your air flow will be less important, so the bottle will drain less quickly.

Diving Conditions in Sri Lanka

The visibility does not rival that of the neighboring Maldives, but you can expect between 15 and 30 meters.

Sea currents: No very violent currents in Sri Lanka, however, pay attention during periods of full moon or black moon.

Tips for Successful Dive in Sri Lanka

To dive in good conditions, here are some tips that you need to apply. These tips are valid for diving in Sri Lanka or elsewhere.

  • Remember to hydrate, to drink water.
  • Eat between 2 dives to regain energy.
  • Take Mercalm if you are seasick: between two dives, you sometimes have to wait a little.
  • Never, and NEVER, panic! Be relaxed because it is a hobby
  • Go down at your own pace, especially if your ears are hurting. It is useless to speed, better to go down slowly, go up a little to depressurize the ears and go down quietly.
  • Be reassured by the management team if you need it, and do not hesitate to ask them your questions.
  • Do not fly within 24/48 hours of your dive.
  • Avoid drinking alcohol and smoking the night before.
  • In case you have any open wound, skip diving. If you are still up for the diving adventure, cover the wound before going inside water. You can wear a wetsuit before jumping into the water.
  • Never hold your breath while diving. The instructors will tell you all about the technique. Listen to them carefully when they are giving diving instructions.
  • Check the diving equipment. Majority of the equipment is going to be heavy because it takes you down into the water.
  • Breathing inside water is challenging. Hence, they give the appropriate gear. A professional diving company will teach you the right breathing technique inside the water.
  • Start performing yoga before your diving tour. It helps you to control your breathing pattern.

Just in case you feel pressure in your ears, ask the professional diver to get you up immediately. Your health is of utmost importance.

Note – Do not dive into the water with the underwater camera in the beginning. Learn the technique of diving and then move forward with a camera. Divers get distracted by the camera and tend to get too busy to get a shot underwater. First master the art and then use a camera.

Concluding Thoughts

We hope you found all your answers here!

The price of the scuba diving package goes up during peak season. In case you want discounts, consider going in a group. Getting a group discount is easier because that way the tour operator does not lose extra bucks. Please note that scuba diving is an experience of a lifetime. It will bring you closer to a calm, serene, and different world. The aquatic life is extraordinary! You can swim with whales, say hello to the fishes, and even swim through caves underneath.

In case you a certified driver, it is advisable to carry your own diving gear. In case you want to get certified, there are a number diving schools that will teach you how to dive and will give a legit certificate.

Generally, it will take 3-5 days to get the diving certificate. Be ready to pay anything up to $500 to get certified. But, it is a good investment considering you will learn all the techniques. Perhaps you could stay in Sri Lanka and teach diving to avid travelers. Learning a skill always helps! You could be anywhere in the world and still use those same diving skills.

Scuba diving in Sri Lanka can be extremely fun and memorable. All you need to do is choose the right operator for the tour. If you choose an amateur, the diving tour will never be safe or memorable. A good tour operator knows the best spots to dive and they will ensure that you have a wonderful experience.
