Koh Samui

Koh Samui is a stunning island resort in the Gulf of Thailand, offering visitors the chance to experience outstanding beaches and a wide range of activities to suit all budgets. Located 700km south of Bangkok, Koh Samui is located in an archipelago of over 80 islands and is one of the most popular holiday destinations in Thailand.

Historically, Koh Samui was a sleepy paradise inhabited by fishermen and coconut harvesters who enjoyed the tropical rainforests and tranquility of the pale sands and crystalline waters which surround the island.  However, over the years, Koh Samui has combined its natural beauty with modern facilities to become a world-class travel destination offering something for everyone. Koh Samui’s beach resorts at Chaweng and Lamai provide outstanding restaurants serving delicious Thai and international cuisine as well as lively bars and nightclubs.

For those seeking a more relaxing holiday, Bo Phut offers the peaceful palm-fringed beaches and charming Chinese-style houses reminiscent of the sleepy origins of Koh Samui. Sports fans can enjoy Muay Thai training and golf, whilst Koh Samui also offers scuba diving and other watersports.  World-class kayaking is also available at nearby Ang Thong National Marine, which provides a perfect day trip from Koh Samui.  Holiday visitors to Koh Samui can also enjoy cooking classes, yoga instruction and a multitude of other leisure activities. The third largest island in the country, Koh Samui deserves its reputation as Thailand’s paradise island, effortlessly combining its natural charms with modern amenities and entertainment options to make it the perfect beach holiday destination.

Below gives you information and a rating of the best time of year to visit.

Why not combine with Bangkok, Chang Mai or another island?

March

April

One of the hottest months to visit but the humidity begins to creep up too so be wary of this if you’re looking to visit this month.

Why not tie in your visit with Songkran, a thee day celebration of Thai New Year. One unique element is a big water fight which couldn’t come at a better time with the hot weather.

May

A nice time to visit Koh Samui with weather very warm and rainfall relatively low.

June

A nice time to visit Koh Samui with weather very warm and rainfall relatively low.

July

A nice time to visit Koh Samui with weather very warm and rainfall relatively low, even if it is quite wet in other parts of Thailand. Travel early in the month to avoid the price hike that comes with School Holidays.

August

It’ll be more expensive to travel this month due to school holidays and because it’s one of the only places in Thailand to experience hot and dry conditions but it’ll be worth it.

September

It continues to be warm though you can expect some short, sharp showers in September. If you’re looking to experience less crowds, travel from the middle of the month when schools have gone back.

October

One of the quieter months to visit if you’re looking for lower crowds and prices. Reason for this is the higher chance of rainfall and increased humidity to go with the warm weather conditions.

November

One of the quieter months to visit if you’re looking for lower crowds and prices. Reason for this is the higher chance of rainfall and increased humidity to go with the warm weather conditions.

Other Thai islands may be better options for better weather conditions in December.

December

The wet season begins to subside but chances of some rain will still be high on your visit. Other Thai islands may be better options for better weather conditions in December.
