The Seasons on Koh Samet
Koh Samet has two seasons in the main, a hot and dry season (high season) and a rainy season. Although Ko Samet doesn’t suffer like other islands around monsoon season it’s advisable to know the best time to travel to suit your itinerary.
Hot And Dry Season
With Daily temperatures rarely dropping below 30 degrees the best time for sun worshippers to visit Koh Samet is between November and the end of April. Although you can expect some rainfall throughout this period it’s never to frequent and very short lasting. April is the hottest month of the year with temperatures reaching 32 degrees. This period is also the High/peak season for visiting the island.
From May the amount of rain gradually increases on Ko Samet until the end of October. This period forms the rainy season. ( Note that the boats to the island still run regular schedules. ) Temperatures will reach highs of 30 degrees consistently through the rainy season meaning you can still enjoy the beautiful beaches of Koh Samed all year round. Expect the occasional day long thunderstorm but in the main rainfall will only last up to a couple of hours each day and falls mainly in the late afternoon or evening time. The increase in rainfall does mean that accommodation prices at preferable rates can be found during the low season.
