Diving at Koh Haa Ao Nang, Krabi
A boat trip from Ao Nang to this cluster of 5 islands will take around three hours. Even so, the clearer water and biodiversity make it a worthwhile journey.
This guide offers information about the Koh Haa dive site, with important details about the marine life found near the shores of the Andaman Sea.
When is the Best Season to Dive Ao Nang?
Generally speaking, you can go snorkeling and scuba diving near Krabi and the offshore islands all year round.
Even so, you'll experience some of the best scuba diving in Thailand in the calm and flat seas from the end of November through to May.
Furthermore, you should still expect to have sea temperatures around 29° Celsius (85° Fahrenheit) even during the winter months.
More than 100 islands offer divers an exciting variety of gentle sloping reefs, shallow swim-throughs, and underwater caverns.
You'll also have an opportunity to see several hundred different species of fish around seven distinct island destinations. The archipelago is only a short boat trip from Aonang, and always popular for scuba diving courses and snorkeling adventures.
Here's the thing:
Advanced or experienced divers are more likely to appreciate the deeper spots at the Phi Phi Island dive sites. This is an ideal location to see big fish, aquatic invertebrates, and colourful coral formations.
The optimum season for scuba diving in Krabi and Ao Nang peaks between the months of December and April. The dry sunny high season offers tranquil warm water diving and underwater visibility in excess of twenty (20) metres (65 feet).
Dive shops operate for most of the year. Nonetheless, the sea conditions will deteriorate from June and often result in heavy rainfall around the Andaman Sea and Phuket dive sites towards the end of October.
Pro Tip: The south-west monsoons, and general bad weather during the rainy season, both affect the underwater clarity and often produce choppy boat crossings. Hence, novice scuba divers should find better conditions in Koh Samui dive spots or Koh Tao diving sites in the Gulf of Thailand from May to September during the Andaman low season.
