The Andaman Sea near Phuket is known for its clear water, coral reefs, and rich marine life. Most tourists come here for the beaches and islands, but these waters have another interesting side. Sometimes, in the open sea, you can encounter large marine animals, dolphins and even some species of whales.
Many travelers ask the same question: are there dolphins in the Andaman Sea, and is it really possible to see them during an excursion? The answer is yes. These marine mammals do live along the coast of Thailand, although encounters with them do not happen every day and always remain a pleasant surprise.
Whale and dolphin watching near Phuket: species and seasons
Several species of marine mammals can be found near the coast of Phuket. Most often, travelers spot dolphins that follow boats or appear near the islands. They move actively through the bays and sometimes come quite close to the boats.
In these waters, you can encounter:
- the Indo-Pacific humpback dolphin
- the bottlenose dolphin
- the rare Irrawaddy dolphin
- occasionally dwarf sperm whales
The question of whether there are dolphins in the Andaman Sea is often discussed among divers and marine guides. Observing them is considered a rare but very memorable experience.
Interesting fact: according to Thai marine biologists, more than 20 species of marine mammals live in the Andaman Sea. Some of them appear near the islands only at certain times of the year.
Sometimes, whales can also be seen in the Andaman Sea, although such sightings are extremely rare and usually occur far from the shore. If you’re lucky, you may spot dwarf sperm whales or beaked whales slowly swimming through the turquoise waters. These encounters add a special magic to sea trips and become a memorable part of a Phuket vacation.
Marine guides recommend going on morning boat trips, as the water is calmer and the chances of spotting dolphins and whales are higher.
When and where it is possible: the best months and departure points
Observation of marine mammals depends on the season, weather conditions, and the boat route. There are no guaranteed spots in the Andaman Sea where animals appear daily. However, there are areas where the chances of encountering them are higher.
The best locations are around the islands south of Phuket. Here, the water is deeper and the marine ecosystem is richer.
Dolphins are most often seen:
- near Maiton Island
- around Racha Yai and Racha Noi Islands
- along routes between the Phi Phi Islands
- in open sea areas between the islands
That’s why many sea programs include these destinations. During the trip, the boat passes through areas where dolphins in the Andaman Sea are most commonly found.
The best time for sea trips is roughly from November to April. During this period, the sea is calmer, water visibility is better, and the chances of spotting marine animals are slightly higher.
A good example of such a program is a sea excursion to Racha Noi, Racha Yai, and Maiton Islands. During this trip, participants not only relax on beaches and go snorkeling but also pass through areas where dolphins can sometimes be seen in the open sea. These encounters always happen unexpectedly and become one of the most memorable moments of the day.

Responsible wildlife watching: how not to harm marine animals
Observing marine animals should be done with care. Dolphins and whales are sensitive to noise and sudden movements of boats. That’s why guides and captains try to follow international recommendations for safe observation.
There are simple rules that help keep animals calm:
- do not approach the group too closely
- do not chase dolphins at high speed
- do not feed marine animals
- do not throw trash into the water
These rules are used in many countries, including Thailand. Responsible behavior helps protect populations of rare species and allows people to observe them without causing stress to the animals.
Where to see dolphins in Phuket with the whole family
Although encounters with marine animals in the open sea are always a matter of luck, there is a place on the island where you can meet dolphins for sure. This is the Nemo Dolphinarium.
The show takes place in a modern indoor complex opened in 2015. The venue accommodates around 900 spectators, and the performance lasts about 45 minutes. During the show, dolphins and sea lions perform acrobatic tricks, play with balls, and interact with trainers.
Before visiting the show, guests should keep a few simple things in mind:
- it’s better to arrive about 15 minutes before the start
- the front rows may get slightly splashed with water
- you can take photos with a dolphin after the show if you wish
Such a show is especially popular with families with children. The animals demonstrate impressive agility, and the atmosphere of the show is very dynamic and fun.
