Encounters with box jellyfish in Phuket, among the most venomous creatures on Earth, add a thrilling dimension to the underwater world of Thailand. Found in the waters surrounding Phuket, these small yet potent jellyfish, with tentacles reaching up to 10 feet, present both beauty and danger. Their sting, powerful enough to be fatal, makes them a fascinating subject for divers exploring the depths of the Andaman Sea.

Jellyfish, resilient survivors of 500 to 700 million years, have evolved sophisticated self-protection mechanisms. Scuba divers may inadvertently cross the stinging tentacles of a jellyfish, resulting in painful yet treatable encounters. Some jellyfish stings, however, pose a greater threat due to potent toxins..

While in search of food, jellyfish can inadvertently interact with swimmers, divers, or surfers. At times, they travel in captivating groups, and observing them from a safe distance is a spectacular sight. However, caution is advised as jellyfish often wash ashore, maintaining their sting even in death.

Scuba Dive Vacation Phuket

For divers like myself, who live in the Rocky Mountains, winter means regular ice and snowstorms, navigating slippery roads around town, and waiting for the snowplough guy to show up. We expect winter to last from November through May, and we don’t whine when it begins in October and ends in June. However, by the time January rolls around, we’ve already had three months of winter, the holiday festivities are over, and our thoughts turn toward the sunny beach.

We daydream about white sandy beaches, warm clear water, colourful coral reefs, lazy or swarming marine life, and the setting sun over rippling waves. Non-divers, as well as friends and family of divers, feel a deep urge for warm tropical breezes, fascinating geography and sumptuous accommodations. Scuba divers, anyway we look at it, can find someone to join us enthusiastically on our next beach getaway.

Planning a scuba dive vacation can be a daunting task, but it doesn’t have to be. With a little planning, you can have an amazing and unforgettable experience. Here are a few tips to help you get started:

Choose your destination. There are many great places to go scuba diving, so it’s important to choose a destination that’s right for you. Consider the type of diving you want to do, the time of year you’re travelling, and your budget.

Do your research. Once you’ve chosen a destination, it’s time to do some research. Read reviews of dive operators, learn about the local marine life, and check the weather forecast.

Get certified. If you’re not already certified, you’ll need to get certified before you can go scuba diving. There are many different certification agencies, so do some research to find one that’s right for you.

Pack your gear. Make sure you pack all the gear you’ll need for your trip, including a wetsuit, mask, snorkel, fins, regulator, buoyancy compensator (BCD), and dive computer. You may also want to pack a dive light, camera, and underwater slate.

Book your flights and accommodation. Once you have everything else sorted, it’s time to book your flights and accommodation. Be sure to book early, especially if you’re travelling during peak season.

Get travel insurance. It’s always a good idea to get travel insurance when you’re travelling abroad. This will protect you in case of any unexpected events, such as lost luggage or medical emergencies.

Relax and enjoy your trip! After all your hard work, it’s time to relax and enjoy your scuba dive vacation. Be sure to take your time, listen to your dive guide, and have fun!

So let’s dream the dream dive. Here are some questions to consider when planning your next dive trip:

1) Where do I want to dive?

Some of my warm water favourites include Cozumel, Mexico and almost any site in the Caribbean. Of course, the Great Barrier Reef of Australia is another popular tropical destination for divers with more available time. A cool water suggestion is the Fiji Islands. Your local dive shop, scuba travel guide, or internet search can provide more or less exotic recommendations depending on your preferences.

2) Should I travel with my equipment or rent equipment at my destination?

Personally, I prefer diving with my own, previously fitted, well tweaked, and properly maintained equipment. I recommend at least taking your own wet suit, regulator, and mask; these are personal items where hygiene is important. If you like your fins, take them with you; they lay flat a the suitcase. It can be a hassle getting your gear in and out of airports not to mention your suitcase, so some travelling divers find it easier to rent their equipment. Most dive operations offer rental equipment. Be aware that some offer higher quality equipment than others. Know before you go. If you decide to take your own equipment, take your regulator to your local dive shop for inspection and parts replacement, if needed. To be sure, try out your equipment in a scuba pool. Diving in your own gear is the best, but faulty equipment can ruin an otherwise great dive trip.

3) Do I want a package dive deal (best) or separate fees that I manage and choose?

Dive packages are often the least expensive way to dive, especially when you bring a dive buddy. How many dives and how many tanks of breathing gas are in the package? What other perks come in the package? Remember to take your diving certification card(s). Most dive operators require proof of certification, and some need proof of skills.

4) What kind of accommodations do I want?

The offerings are as plentiful as they are diverse. You may want a cabin on sparsely populated beach, a beach with a pulsating nightlife, or luxury accommodations aboard a cruising yacht. How many nights are included? Are meals included in the price? How many meals, snacks, beverages? You may be surprised at the array of offerings out there. Just know that there is a match for every budget and any time frame. Just ask a scuba travel guide.

5) Do I want to take underwater photographs?

Three to four dives per day are common on a dive vacation. Serious underwater photographers wouldn’t think twice about taking their camera equipment. They wouldn’t want to miss the opportunity to snap that stunning coral reef, rare seahorse, or super whale shark. Many hotels and resorts provide special areas with ample power outlets and large work tables for photographers to work. And, inexpensive underwater cameras allow novice photographers to enjoy underwater pictures of their friends and treasures.

When should I plan my dive trip?

Now is a good time. It’s best to make reservations well in advance, so start planning!

Why Do Divers Have to Wait to Fly?

Flying after diving

The answer relates to pressure inside the body. If the surface is the baseline, each person has one atmosphere of weight at this level. Divers do not notice this weight. However, for every 33 feet (10 meters) of sea water (fsw = feet of seawater) that a diver descends on a dive, another atmosphere of weight is added to the pressure. This pressure turns nitrogen in the blood into solution, and the plasma becomes supersaturated. During ascension, the opposite is true. Pressure decreases as dives ascend altitude. The decrease in pressure causes nitrogen to come out of solution and form bubbles in the blood stream.

Bubbles form when divers

  • ascend to the surface after a dive
  • ascend to altitude after a dive (as in flying)
  • ascend to a higher surface altitude without pressure

During the required wait time, divers’ bodies blow off saturated nitrogen bubbles and reduce pressure before flying. It is the same reason divers use surface intervals between dives. It is also the reason divers make safety stops on the way up to the water’s surface after each dive.

Recommendations for Flying After Diving

The Professional Association of Diving Instructors (PADI) and Divers Alert Network (DAN) recommend the following wait times for flying after diving:

  • A minimum pre-flight surface interval for a single dive is 12 hours.
  • A minimum pre-flight surface interval for repetitive dives or multiple days diving is 18 hours.

Following these recommendations greatly reduces the risk of decompression sickness (DCS). The recommendations do not guarantee 100% that a diver will avoid DCS, which is also known as the diver’s disease called the bends. Another important factor to consider is dehydration. Divers should stay well hydrated when on a dive trip.

Flying After Diving

Diving After Flying

Diving after flying is not a problem. Divers can head straight to the ocean for a dive upon arrival at the airport without the risk of DCS.  High concentration of nitrogen in the blood occurs only after diving. The nitrogen typically becomes supersaturated and forms bubbles at lower pressures. Before the first dive, a normal amount of nitrogen is in the blood.

Note that longer flights allow more time for dehydration, which is also a problem in DCS. Scuba divers should drink plenty of non-alcoholic fluids on a long flight to prevent dehydration. Some divers tend to arrive in a hot country and head straight to the bar. However, alcohol contributes to dehydration, so drink extra water.
