Already the start of July, we're entering Koh Tao's summer season which is a great time for scuba diving here. At Simple Life Divers we get a lot of emails asking what can be expected diving Koh Tao at this time of year. So here's a run down, giving you a better idea of what you're likely to see around the Koh Tao dive sites, and general aspects of visiting Koh Tao during July, August and September.

Myth No. 1: It's low / monsoon season in Koh Tao during Summer.Koh Tao has great year round weather and diving conditions, except for November when we get some rain. July, August and September have warm, sunny weather with very little (if any) rain, and excellent diving conditions. Underwater visibility is generally good so you get to see masses of tropical marine life, and wave heights are usually low which means we can visit all of Koh Tao's best diving sites. In fact, summertime is low season for dive operators on Thailand's Andaman coast. Why? The prevailing wind at this time of year blows from the South-West, so there's a very long fetch causing large waves for Thailand's Andaman coastline [Phuket, Koh Phi-Phi, Lanta, Koh Lipe etc]. Koh Tao is located in the sheltered Gulf of Thailand towards the western side of the gulf, hence we're much better protected and have great scuba diving conditions throughout during July, August and September. So what can you expect to see around the Koh Tao dive sites at this time of year?Whether you're taking a PADI Diving course [such as PADI open water] or just enjoying our daily Koh Tao dive tours if you're already a certified diver, you'll get to visit a mix of shallow coral reefs and deep pinnacle dive sites. Our coral reef dive sites include Twins and the Japanese Gardens off Koh Nangyuan, White Rock and Mango Bay to the north of Koh Tao. On these sites you're guaranteed to see masses of tropical coral reef species. This includes colorful reef fish such as butterfly-fish, angel-fish and wrasses, plus more diverse marine species such as white eyed moray eels, blue spotted sting-rays and banded sea-snakes. We also regularly see hawks-bill turtles, and the famous territorial Koh Tao trigger-fish. Koh Tao's deeper pinnacle dive sites such as the Chumphon Pinnacle and South-west pinnacle are home to our larger marine species, and visibility is usually excellent above the thermocline which sits at 25-30 meters. You can expect to see giant groupers, bat-fish, barracuda and jacks, with enormous fish populations congregating around the pinnacles.

Diving with Whale Sharks in Koh Tao?
Everyone that comes diving in Koh Tao wants to see a whale-shark, but how likely are you to see one? The truth is you've got to be very lucky. We see whale sharks every few weeks, but it's impossible to predict exactly when they're going to show up on the Koh Tao dive sites. Your best chance would be diving at the deep pinnacle sites during September, which has a high frequency of whale-shark sightings each year. 2009 has been a good year for whale-shark sightings, and we'll continue to keep you up to date on this news feed.

A bonus for the coming season is that we have a new wreck dive on Koh Tao. A small wooden boat became damaged, and was dragged to Koh Nangyuan and sunk as an artificial reef. The wreck is located just off the reef at the Japanese Gardens dive site, and although small, makes an interesting addition to the dive site. The wooden hull resting in shallow water won't last long, as the high oxygen content will cause the wood to degrade rapidly, so the wreck will only be intact for a couple of seasons at most. High Season or Low Season?July and August are definitely one of the busier periods here on Koh Tao island. Along with late December and January it's Koh Tao's busiest times of year. Diving Koh Tao is never a problem, as with more than 25 dives sites close to the island and great scuba diving conditions there's always something new and exciting to see. But accommmodation is in high demand, especially on Sairee Beach which is the most popular area on Koh Tao. This demand is multiplied before and following the famous Full Moon Parties on Koh Phangan. If you plan to visit Koh Tao around any of those dates, it's wise to make accommodation bookings in advance. Otherwise you will end up facing a situation where all the quality and reasonably priced Sairee Beach accommodation is full, leaving only overpriced or sub-standard rooms available. |
