Weekly Dive Report – May 5th – 11th

Welcome to our round up of what has been another fantastic week of diving on Koh Tao! We’ve had some slight swell and mild currents around the island this week, however visibility is still amazing, and we’ve seen more fantastic marine life yet again!

This week, we visited Chumphon Pinnacle, Southwest Pinnacles, White Rock & Twins.

Sunny with a Chance of Whale Sharks

One of the things our customers ask most often is whether they will be able to dive with Whale Sharks during their stay with us. We very much hope so, but unfortunately we can never promise specific marine life sightings.

Despite what some online sources and business operators say, there really is no such thing as ‘Whale Shark Season’, and no guaranteed shark diving on Koh Tao to be honest. We do get the occasional sighting of black tips as well as whale sharks, but it can never be guaranteed. There are dive sites where they are spotted more frequently than others, and a few trends at times of year when its statistically more possible, but it basically comes down to luck – being on the right dive site on the right day at the right time!



In recent years we’ve seen the most Whale Sharks in March-May, September-October and then again around Christmas and New Year time. However do be aware that visiting during these months will not necessarily mean you get to dive with one. And they are frequently seen sporadically outside of these months too – for example in the last couple of weeks there have been a few spotted out at some of our deeper dive sites. When we do see them, they tend to be solitary encounters though, unlike in other destinations such as the Philippines, where at certain times of year you can dive/snorkel with many at the same time.

2017 was a particularly epic year for sightings of our favourite blue spotty fish, with an unprecedented number of sightings throughout April and May – which we dubbed Whale Shark Central. the Department of Marine Conservation released statistics that they had identified over 90 different individual Whale Sharks in the Gulf of Thailand last year! This is great news, so we are hoping they will all stick around this year and going forward in years to come!

Whale Shark!


The dive sights where you are statistically more likely to have an encounter with one of these gentle ocean giants are the deeper sights such as Chumphon Pinnacle, South West Pinnacle and Sail Rock, although they have also been spotted at intermediate dive sites such as Green Rock and Hin Pee Wee. Very occasionally they have been seen at shallow dive sites like Twins, but generally to increase your chances of a sighting you’d need to be deeper, so being Advanced Open Water Diver, or at least having completed a Deep Adventure Dive.



Ocean news 2017 in Review – Part 1: The Changing Earth

During 2017, we experienced some highs and lows when it came to ocean-related news. New discoveries mixed with natural disasters of the greatest proportions riddled our timelines throughout the past year, so I figured it would be an interesting topic for a 2-part blog series. With this entry: The Changing Earth, I’m going to discuss the various threats to the oceans and Earth as we know it, with the next installment focusing on the positives that came out of 2017, including exciting new discoveries! So, without further ado, let’s discuss some of the interesting ocean-related events of the past year, starting with the numerous devastating tropical storms….


2017: The year of “once in a lifetime” storms! While hurricanes and strong tropical storms are not uncommon events, last year we witnessed some of the strongest storms in history. The Caribbean was hit by not one, but two huge hurricanes back to back in late August. Hurricane Harvey initiated the onslaught on the region, dumping up to 150cm of rain over a 2 day period. This lead to insane flooding causing large scale personal and property loss that is estimated to reach $100 Billion US dollars. Hurricane Maria followed around a month later, which caused the near annihilation of Puerto Rico, whose inhabitants just got their power back within the last month! Unfortunately, these weren’t the only storms of note. A post-tropical cyclone made its way north and hit both Ireland and Great Britain. Stronger-than-usual typhoons were experienced in south-east Asia, and a seldom heard of Medicane occurred in Greece. Have you ever heard of a Medicane? These storms are the Mediterranean equivalent to a tropical storm, much like a cyclone or typhoon. However, since the Mediterranean isn’t big or warm enough to sustain the storm’s energy, it can’t be classified as a tropical storm, despite sharing tropical storm characteristics. Hence the creation of the title “Medicane”.

While this past year was a bad one for storms, it is a sign of where we are going with future years. Thanks to global warming, we can come to expect these types of storms to become part of the norm.

In addition to the storms, 2017 will also be known as the successive year where we documented the further demise of our coral reefs. A mass bleaching event occurred throughout the world in 2016 due to the El Niño weather pattern causing water temperatures on the coral reefs to increase. This initially started back in 2014, however due to the sustained higher-than-usual water temperatures, 2016 was the year we saw the most bleaching and coral die-off. While this isn’t an immediate death sentence for the corals, if the higher-than-usual temperatures are sustained, the corals will become stressed, expel their symbiotic algae with whom they coexist and use as a food collection source, and slowly starve.   All is not lost though! Marine protected areas (MPA’s), coral nurseries, pollution reduction, as well as the discovery of “super corals” have all played a valuable role on helping reefs bounce back after this very trying time period.  These super corals are species that are able to withstand a greater temperature variation than other species of corals, which means that these El Niño events aren’t impacting them nearly as much as the regular corals. Pollution, while down overall, is still a major threat to the health of the oceans. It includes anything from oil spills, fertilizer runoff, and the subject of the year: Plastics!

Plastics, plastics, plastics! It seems like this is a never-ending topic of discussion among environmentalists the past few years and 2017 is no different. The issue has become what most would describe as an epidemic, to the point where scientists have estimated that there is a literal tonne of plastic rubbish located in the oceans from each person on Earth. What’s worse is that the majority of this plastic enters the water through only 10 rivers across the globe. On a slightly brighter note though, scientists discovered that some species of corals actually eat plastics! It appears that the corals enjoy the taste of the plastics, however, scientists have yet to figure out what chemical or component of the plastic makes it so desirable to the coral. Humans are learning something new every day and will hopefully use this newfound knowledge in a positive way! Here at Master Divers, we try to lead the way on Koh Tao, and take every step possible to reduce our plastic consumption. You can read more about Master Divers commitment to the environment on our previous blog post.

Eco Straws


Given all that has happened in the past year, it is easy to be sad, but don’t be! Channel that passion into energy to help solve the problem! With the biggest issues all being due to global warming, we can all start with trying to lower our carbon footprints.  This includes carpooling, walking, cycling, or using public transit to get around instead of driving everywhere. Another step you can take is to limit your meat intake. I’m not going to preach to you and say you need to cut out meat 100%, but if you can limit the amount you eat in a given week, it would do the world of good. Forests are cut down in order to make pastures for cattle and create food for other animals raised for human consumption. Finally, I implore you to try and cut down on the amounts of single-use plastic you use. Excellent alternatives to popular single-use plastic items exist, such as metal or bamboo straws and canvas shopping bags. The Earth needs our help if it is to be saved, and only a change in what has become our “norm” will do. Tune in to my next blog post to see what other changes 2017 brought to the world for ocean lovers!

The Eco-conscious Island of Koh Tao


Exciting news….Koh Tao could soon be known as one of the most eco-conscious destination of South East Asia! Many businesses, including most dive shops, are working together to try and ban single-use plastic items on Koh Tao, including plastic straws and plastic bags. On top of this, efforts are being made to install a recycling program for businesses to have their recyclable goods picked up rather than throwing them in with their everyday rubbish. This was all made possible by Koh Tao’s inhabitants having an eco-conscious mind set and the determination to fight for change.

The term ‘eco-conscious’ is floated around a fair amount in the media these days, but what does the term really mean?

An eco-conscious individual or business has a way of thinking where they look at how their actions and choices impact the natural world. Dubbed eco-warriors, these people/companies are both very aware of the threats faced by our fragile world, and also work to reduce and ultimately eliminate their impact on those threats. Where plastic is concerned, this largely revolves around ‘The Three Rs’… Reducing  plastic use, Re-using any plastic that is used, and Recycling whenever possible.

Here on Koh Tao, with diving being the primary activity that draws tourists to the island, many inhabitants are already far too aware of the global plastic problem, ans its impacts on our oceans and marine life, and have been puching for changes for some time now.

As an island, there has already been some success in previous years. Just over 4 years ago the local government banned the use of styrofoam boxes, which were commonly used as takeaway containers from restaurants. This milestone showed that the community was willing to make sacrifices when alternatives are present, and when it was in the best interest of the island. Once a few people come around to a more sustainable way of living, it soon catches on, and now we have several key figures in the municipality on board, including the Mayor of Koh Tao! He understands that the island’s natural beauty (both above and below the ocean’s surface) is one of the main reason people choose to spend their vacation here, so it is worth making rulings to help protect it.

The latest introduction to Koh Tao to reduce and eliminate plastic waste is the sale of reusable straws (paper, metal and bamboo), with the hope that if the alternatives are available, single-use plastic straws will be phased out entirely.

So, first it was styrofoam, now plastic straws and the next step will be to remove plastic bags from our little island paradise. Its a huge goal, but with enough people involved and the right mindset, we’re not alone in pushing for change and committing to making it happen!

So, what can you do to help?

In short, the best thing you can possibly do is STOP USING PLASTIC as much as possible in your day to day life! And especially single use plastic. The great news is that alternatives are already available. Master Divers is proud to be a vendor of paper, bamboo and metal straws, and our retail section is well stocked with reusable water bottle and cloth shopping bags, meaning you’ll have no need for plastic bottle or cups, plastic straws or plastic bags. And the best bit? You get to take them all home and spread the word!

Please do join us in considering the environment, and not just in Koh Tao. It does not take much effort to live with less plastic in your life, it just takes a little more planning and forethought, but the results are well worth it!
