Conditions this week were mainly calm with a little wind on the East coast, but waves were minimal. The visibility has been fantastic and our favourite shots this week were those that showed just how crystal clear the water was. Everything looked so pretty and colourful!

Weekly Dive Site Report 18 – 24 August 2017

Hi everyone and welcome to Master Diver’s weekly diving report, bringing to you all the news, from myself, Rob Kelly, about diving in Koh Tao this week.

This week’s worth of diving has bought an abundance of marine life to enjoy, with some very up close and personal encounters. We have enjoyed beautiful conditions at a broad range of the sites we have visited.

On a couple of days this week we had advance notice of minor squalls, resulting in slightly choppy surface conditions. Fortunately, with the heads up from our management team and the 30+ years experience of our legendary lead captain P.Dong we always managed to find the optimum dive location for our divers and customers who were snorkeling.

Highlights for this week in our photo blog are Japanese Gardens, Twins, Chumpon Pinnacle and the Koh Tao reef regeneration project called Junkyard.

My personal favourite encounter this week, was a Green Turtle, fascinated by his reflection in my camera dome at Twins dive site, one that we often visit scuba-diving Koh Tao. We hope you enjoy the pictures as much as we enjoyed diving these sites. See you next week!
