Diving from Ao Nang Beach

...Good for: Small animals, beginners, snorkelling and non-diving activities
Not so good for: Drift dives and advanced divers...

This scenically spectacular region of southern Thailand consists of a group of 7 main islands dotted around Koh Poda - Koh Ha, Koh Si, Koh Yawabon, Koh Dor, Koh Talu, G.K. Island and Koh Yawasam. With over 200 species of fish and 80 species of coral catalogued, the local marine life that you'll see when you're diving in Krabi is both diverse and prolific. The region lies within the Hat Nopparat Thara - Mu Koh Phi Phi Marine National Park and the dive sites around the islands are a mere 30-40 minutes boat ride. This makes them ideal destinations for handy daytrips out of Ao Nang Beach.

Koh Ha is 500m south west of Koh Si and contains at least 60 species of corals and many of the gorgonian seafans. The east side has mainly staghorn reef, whereas the south east section features a wall to 18m with many coral whips and sea fans hosting a fascinating range of shrimps and crabs. This Ao Nang dive site often has large schools of barracuda, small groups of squid and cuttlefish, and early in the morning stingrays and leopard sharks are often found lazing in the sand.

Diving Season in Krabi

Scuba diving in Krabi runs all year round from Ao Nang Beach, but the best conditions exist from November to April. Late May to October brings monsoon winds and surface swells, reducing visibility at the dive sites in Ao Nang by about 20%, but it is pretty rare that trips are cancelled due to bad weather.

Sea temperatures in the area remain reasonably constant from a high of 30°C in the dry season to a low of around 27°C in rainy season. The leopard shark is one of the signature creatures for fun divers in the Krabi region and can be spotted throughout the year.

October also brings heavy rains to the Andaman Sea. From May to August, the weather is better in the Gulf of Thailand, so you might consider diving in Koh Samui.
