Songkran (Thai New Year) – April
Songkran, celebrated in mid-April, marks the start of the Thai New Year and is one of the most famous festivals in Thailand.

Beyond the fun, locals participate in religious ceremonies at temples, where they make merit and offer prayers for prosperity and health. Songkran in Koh Samui is a must-experience event, combining traditional spiritual rituals with modern revelry.
Loy Krathong – November
Loy Krathong is one of Thailand’s most visually stunning festivals, celebrated in November under the light of the full moon. Participants release beautifully decorated floats, or krathongs, onto lakes, rivers, and seas to honor the water spirits and ask for forgiveness for any harm caused to the environment. The festival also symbolizes letting go of past grievances and starting anew.

In Koh Samui, popular locations such as Chaweng Lake and Bophut Beach glow with hundreds of floating krathongs, creating a magical atmosphere. The festival includes music, dancing, and traditional performances, making it both a spiritual and cultural highlight for the island. For many, Loy Krathong is a deeply reflective experience, and watching the illuminated floats drift away is a moment of peace and gratitude.
Full Moon Parties – Year-Round
Though not a traditional Thai festival, the Full Moon Parties held on nearby Koh Phangan have become iconic events for many visitors to Koh Samui. These all-night beach parties attract thousands of partygoers every month to celebrate under the light of the full moon, with music, dancing, and fire shows setting the tone.

Many visitors to Koh Samui take a short boat ride to Koh Phangan to participate in the world-famous Full Moon Parties, though there are often smaller celebrations on Koh Samui itself, especially in Chaweng. These parties are a vibrant part of the island’s modern culture, mixing international influences with local flavors, offering visitors an unforgettable nightlife experience.
Chinese New Year – January/February
With a large Chinese-Thai community, Chinese New Year is another significant celebration on Koh Samui. Taking place between January and February, depending on the lunar calendar, this festival is filled with bright colors, traditional lion and dragon dances, and fireworks lighting up the sky.

Temples around the island, particularly in Nathon and Maenam, become the focal points of celebrations as families gather to make offerings and pay respects to their ancestors. The streets are filled with lively parades and performances, creating a festive atmosphere that draws both locals and tourists. The Chinese New Year is a time of feasting, family, and good fortune, with businesses and homes blessed by the traditional lion dance, believed to bring prosperity for the year ahead.
Samui Regatta – May
For those with an interest in sports and a love for the sea, the Samui Regatta is one of the island’s premier events. Held annually in May, this international sailing competition brings together sailors from around the world to race in the clear waters off Chaweng Beach. The Samui Regatta isn’t just about the races, though—it’s also a week filled with beach parties, social events, and award ceremonies.

The event showcases Koh Samui’s stunning coastline, with colorful yachts dotting the horizon as they race across the water. It’s a fantastic opportunity to experience the island’s nautical heritage while enjoying the social buzz that accompanies this world-class regatta.
Buffalo Fighting Festival – January/August
One of the most unique cultural events in Koh Samui is the Buffalo Fighting Festival, held twice a year in January and August. Unlike the aggressive bullfighting seen in other parts of the world, Buffalo Fighting in Thailand is more of a ceremonial display, where two water buffalos face off in a show of strength. The event is held with great respect for the animals, and it is considered good luck if the buffalo emerges victorious.

The festival is deeply rooted in Koh Samui’s local traditions, and it draws large crowds, especially among locals. In addition to the buffalo fights, there are markets, food stalls, and traditional performances that offer a complete cultural experience. While it may not appeal to everyone, it provides a unique window into the island’s agricultural heritage and long-standing community customs.
