High Season and Low Season on Koh Samui
The high and low season on Koh Samui are judged according to the amount of precipitation on
the island. Although some tourists prefer to visit the place during the high rainfall days, to enjoy
the lovely weather and rains on the beach whereas some like it dry so as they can enjoy the
great wind and the sports related to it.
Ko Samui’s climate is similar to the rest of Thailand. It is tropical with high temperatures, high
humidity and high rainfall. The year is split into a wet and a dry season. It’s not hard to escape
from the humidity at one of the island’s famed beaches. Still the beaches of Koh Samui are
smarmed with tourists in any season or rainfall levels.
Across the year, there is hardly any seasonal difference in temperatures with each month
seeing daily highs in the low 30’s and minimum temperatures of 23°C to 25°C. The ocean water
temperature stays at a bath-like 27°C for much of the year, so the only thing that really changes
across the year is the rainfall - which varies quite dramatically!
Ko Samui is a popular holiday destination off the east coast of Thailand with the year being
divided into three seasons like:
The rainy season continues from September – November which is also known as the monsoon
season. September usually has more number of hot and sunny days than October or November
which are the months with maximum rainfall. It does not rain at all times during these months,
but rainfalls and thundershowers are very common and there might be times with non-stop
rain for 5-6 days. Due to the finite water supplies of Koh Samui those rain showers are needed
and important for Koh Samui's flora and fauna.
After the rainy season is over, the dry season comes which lasts till Feburary. During this
season, it may rain occasionally but usually there is a lot of sunshine with some refreshing wind
or breeze at this time. This is a great time for wind and body surfing.
From March till August, it is usually very sunny, hot, windy and dry. This is the hot season of
Koh Samui. In May it might rain a little more though. Actually this is the best season to visit Koh
Samui, Koh Phangan, Koh Tao and the National Marine Park, if the temperature range of 28 –
40 C is bearable during the day.
At 228 square km, Ko Samui is Thailand’s third largest island and famous for its full moon
parties which bring revelers together for the all night parties during any season. The Island is
always full of energy and new experiences no matter how rainy or windy it is on that day,
tourists visit from all over the world to enjoy the idyllic beaches, to learn diving or other wind
and water sports.
