Koh Samui weather is very enjoyable throughout the year with temperatures, ranging from 25 to 34C. The climate is tropical and very humid all the year round, but there is always a refreshing sea breeze coming from the Gulf. The best period to visit Koh Samui lasts from December to June, while from the end of September to November there is a rainy season.
To reach Koh Samui, you should first get a ticket from your local airport to Bangkok, Thailand. From Bangkok there is a variety of travel options to Koh Samui. An air-conditioned bus runs from Bangkok to Koh Samui for twelve hours. A travel by bus is a nice choice if you want to enjoy a variability of Thailand's scenery along the way. A night-train goes to Surat Thani (ten hours) and is followed by a bus/ferry transfer to Koh Samui.
Flights to Koh Samui are available in two options. There are direct flights from Bangkok to Koh Samui, operated by the Bangkok Airways, and flights to Surat Thani, operated by the Thai Int. Airways or Orient Thai, followed by a bus/ferry transfer to Koh Samui.
Direct flights to Koh Samui are the most preferred and convenient variant among the others. There are fifteen-twenty flights daily between 6 a.m.and 8 p.m.. However, take care on your baggage in Bangkok. The baggage is not redirected automatically at Bangkok Airport, so you have to pick it up, go to the domestic terminal and check-in your baggage again. The tickets for flights to Koh Samui can be booked both in a travel agency and online by the Bangkok Airways' website.
Flights to Koh Samui are more popular for the panoramic views, while the plane is landing on the island. The bird's eye view of the Big Buddha of fifteen meters long as well as the lush island's vegetation produce a great impression on Koh Samui visitors. Samui Airport is also quite an extraordinary construction. The airport consists of wooden houses, which harmonically enter the surrounding landscape; in addition, it has been rewarded for its style and decoration.
Another option is to fly to Suratthani first. The Thai Airways operate flights to Suratthani from various Thai cities. As you arrive in Suratthani, there are shuttles that make a transfer to Donsak's pier (about one hour), and from there you take a boat to Koh Samui (about an hour and half). This trip is longer, but the prices are more effective as compared to direct flights to Koh Samui. Tastes differ; some people prefer not to waste time, the others - money.
As Koh Samui continues developing into popular tourist destination, new flights to Koh Samui become available. Since recently, Pelangi Airways has started operating flights from Kuala Lumpur to Koh Samui. In addition, Hong Kong (China)- Samui route is in operation since 2005.
