Samui Weather


The Climate in Thailand

Thailand's climate is tropical. High in both temperature and humidity and most people find it very pleasant. The average temperature is about 30 degrees Celsius, or 86 degrees Fahrenheit.

When it is getting too hot, just enter a air conditioned hotel room or shop for a while and you will "recharge your batteries".

Remember to drink a lot of water so you do not become dehydrated. You will probably experience "summer temperatures" here year round, but Thailand and Koh Samui is normally divided into three seasons:

The dry season, the hot season and the monsoon or rain season.


Different than the West Coast

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 rather evident.


Samui Climate and Seasons

Dry Season

December - February: The dry season. Not much rain, but it might occur some refreshing breeze and wind at this time. Great for wind and body surfing. It is normally a lot of sunshine at this season.


Hot Season

March - August: The weather is still dry in this time, and it is usually very sunny and hot. In May it might rain a little more though. This is a great period to visit the islands if you can stand temperatures ranging from 28-35 degrees Celsius at daytime.


Rain Season

September - November: Also known as the monsoon season. It's still hot and normally there are many sunny days in the monsoon period. On some days you might find yourself in a refreshing monsoon shower for a moment. The rain showers are often short and as these island's water supplies are finite, the rain is needed and important.
