Best times to visit Koh Phangan

What is the ideal season to take a trip to the tropical Thai island?

Read on to find out…

Thailand is seasonal, but not in the respectful Western way, with: summer, spring, fall and winter. Thailand seasons depend on the rainfall.

Koh Phangan Seasons:

Dry Season: Jan-April

Koh Phangan is blessed with beautiful weather and calm seas for much of the year.

March and April tend to be the driest months. So if you want to be topping up the tan, now is the time to come.

Rainfall of only 35mm. Wouldn’t recommend seeing many waterfalls as all you can expect is a trickle.

Temperatures – here are very hot during the day, up to 33 degree Celsius. Don’t leave the house without the suncream!

Air-Conditioning is a must in all rooms, and to also avoid that blistering midday sun. (A perfect excuse for a siesta). However you can still do activities all day, but just prepare for you to be in a constant layer of sweat.

Swimming – The best month to swim in the sea is in April when the average sea temperature is 30°C (86°F).  As Koh Phangan has a very low lying sea, meaning the sea water gets beautifully heated up during the day by the scorching sun, so if you think you are going into the sea to cool down, think again.

The sea is general very flat and calm, perfect for kids.

Top Tip – Keep hydrated and take cover from the sun.

Phangan Explorer has had many friends ruined their trip due to taking a visit to the hospital due to one of their dangerous results of too much sun.

Rainy Season: May – June

Rain – With just a little more rain expected from.  However due to this being the tropics if it does rain, don’t worry it probably won’t last, and will clear up will beautiful sunny skies again in an hours or 2.

Temperature  – A few degrees cooler than dry season, but still great t-shirt weather. It never really gets cold in Thailand, locals don’t own coats.

Top tip – Pack light! As you won’t be needing half of the big bulky warm clothes you think you need. Thailand is still very warm in the evenings, so just bring a light jacket in the RARE occasion you will get the chills. (Maybe from being wet from the sea and going on the bike home).

Monsoon Season: October – December

If the prospect of rain really dampens your spirits then this time of year is best avoided. 

Nevertheless, you can still do the activities you would like to do, but just pack a poncho.

Rain – These months are significantly wetter and windier due to the northeast monsoon. These seasons differ every year. On some weeks, it might not be raining all the time; it might just be a few hours of heavy rain here or there. However, you may be unlucky and get a full week of torrential rain.

Temperature – Still fairly hot (as you’re in Thailand). Above 30 degree Celsius with the air being very humid.

Swimming – In this season, on certain beaches, where the sea is exposed to the currents, you get rip currents/ undercurrents. Haad Rin Beach, in the South is particularly bad, with strong, dishwashers like waves, not great for surfing. Rip currents can be very dangerous, even for experienced swimmers, as the sea takes you against your will. However , if you ever get stuck in one, just follow the diagram below.

Wind – Now is the time for wind-water sports (kite surfing and windsurfing, and maybe a bit of surfing). However Koh Phangan is not so well known for surfing, it can still occur.

There are many water sports shops, for you to learn or rent the equipment.

E.g. Monsoon season on some island in the Andaman Sea side (West) are much longer from October-May.

In every season, may there be something for everyone. However it’s always good to be in the know about what to expect.
