태국은 보통 5~10월을 우기로 보고 있으며 우기에는 한 두차례 스콜성 소나기가 내립니다.

꼬 란따는 11월부터 4월까지가 방문하기에 가장 좋은 때이며 5월부터 10월까지는 물결이 세고 비가 내리는 경우가 많아 그다지 여행자가 많지는 않습니다.

WEATHER

The best time to travel to Ko Lanta is from November to April. November is the coolest month of the year with day temperatures of 28 - 30. The night temperature is regularly 5 - 7 degrees lower.

The temperature slowly rises from November until May, in January, you can expect temperatures of 30 - 33 C, in April the temperatures will climb up to 35 - 37C. Occasional downpours are not rare.

The monsoon season lasts from May through to October with temperatures slowly declining to their lowest level in November. During this period, the sea is rough and swimming is not recommended. Most of the smaller resorts on the island close down during this time as there are very few tourists around. Transport available will be only by minibus from Trang and Krabi via car ferries. Divingis not possible due to rough seas and insufficient visibility during this period.

꼬 사무이는 9월~11윌이 우기입니다만 7,8월은 날씨가 무척 덥습니다.

Koh Samui climate and seasons
Thailand's climate is tropical. High in both temperature and humidity. Most people find it pleasant. The average temperature is about 30 degrees Celsius, or 86 degrees Fahrenheit. When it is getting too hot, just enter a air conditioned room or shop for a while and you will "refill your batteries". Remember to drink a lot of water. Even if it is more or less "summer" here year round, you could say that Thailand and Koh Samui has three seasons:
--------------------------------------------------------------------------------
Dry Season, December - February: The dry season on Samui. Not much raining, but it can be a some refreshing wind or breeze on these islands then. Great for bodysurfing. The sun is shining a lot on us at this period of the year!
--------------------------------------------------------------------------------
Hot Season, March - August: The weather is still dry in this time, and rather hot. In May the raining may increase a little. This is a great period to visit Samui if you can stand 30-35 degrees Celsius daytime. The sunshine is still dominating the day time, almost as much as in the Dry Season.
--------------------------------------------------------------------------------
Rain Season, September - November: Also known as the monsoon season. It's still hot and normally, there are many sunny days anyway. Sometimes you might find yourself in a refreshing monsoon shower for a moment. The rain showers often last just for a short while though and as these island's water supplies are finite, the water is needed.
--------------------------------------------------------------------------------
Notice! The climate seasons are not exactly the same as in Krabi and Phuket, as these destinations are located in/at the Andaman Sea and Koh Samui, Koh Phangan and Koh Tao are located in the Gulf of Thailand. This makes the climate differences evident.

제가 8월 20일경 태국으로 여행떠날 계획을 잡고 있습니다.
방콕을 들러 여행하고 바다가 있는 곳으로 갔다가 오는 것이 일정인데요.

처음 그 일정을 코 란타로 잡았습니다. 그런데 어디서 보니까 우기에 코란타는 영향도 심하고 폐쇄하기도 하는 둥 우기에는 가도 별 볼일이 없다고 하더라구요. 그렇지만 또 7,8월경 코란타 다녀온 분들도 계시고 해서 어떤 상황일런지 너무 궁금하네요.

더불어 코 란타가 여의치 않으면 끄라비와 코사무이 중 한곳을 대안으로 선택하려고 하는데 그 두곳을 8월 20일경 어떤 상태를 보이나요?
