The island of Koh Samui is encircled by secluded beaches and crystal blue water.
This popular holiday destination is recognized as the finest for diving in the southern Gulf of Thailand.
In fact Koh Samui and Koh Tao have recorded significant escalations in tourism and travelers throughout the last ten years.
The best time to dive these islands harmonizes perfectly with the rainy monsoon season of the Andaman Sea Resorts and Phuket.
Fly to Koh Samui or take the ferry to Koh Tao for easy diving and unforgettable coral island snorkeling tours around the east coast of Thailand.
Koh Samui and Koh Tao peak diving season is from May until September. The water clarity is at its best during these months and you will avoid the windy wet months of November to February.
There are dozens of dive schools on the two islands and most of them operate all year.
Trips are rarely cancelled due to the weather and diving off season means you still get great dives but the boat rides can be bumpy.
Local diving and snorkeling activities are superb value for money and meet the needs for all levels of certification.
PADI scuba courses are easy to locate and Koh Tao is one of the best-selling destinations for newbies to the community. Dive sites range from 5 meters in some sheltered island bays and you can find deep pinnacle spots at 30 meters if you have the appropriate scuba ticket.
Water temperatures in the lower Thai Gulf rarely fall below 27°C.
The Gulf of Siam is a relatively shallow appendage of the South China Sea flowing from Cambodia to the Bay of Bangkok in the north. The deepest troughs are less than 80 meters below sea level.
Thailand, Cambodia and Vietnam all have borders with this expanse of water which is broadly sheltered from major oceans.
The benefit means uninterrupted high quality diving almost every month of the year. Daily boat trips from Koh Samui reach the best-loved distant sites. The two favorites provide thrilling marine life and frequent sightings of large pelagic fish.
Whale sharks are familiar visitors to the towering submerged pinnacle rocks which provide unwavering magnetism for diving at Chumpon Pinnacle and Sail Rock. Other common creatures include large schools of snappers, barracudas, turtles and the infamous trigger fish.
