The Rainy Season in Thailand Explained  

The Rainy Season in Thailand Explained  

After several months of drought, the heavens have at last opened, and the fairways are getting a well-deserved soaking.

Often known as the Green Season, temperatures drop and in between the rain it is actually a particularly enjoyable time to play golf, when the courses are not too busy.

Remember all Asian courses are designed to cope with these sudden downpours, with large drains, so you can expect play to re commence in a short time. 

Thailand has three main seasons: hot, not-so-hot, and monsoon–commonly known as the wet or green season.

While most people enjoy the rain and see it as a good break from the sunny days, heavy rain sometimes disrupts daily activities.

Thailand has three types of weather driven by an annual monsoon that sweeps across Thailand from the northeast Indian Ocean into the Southeast Asian land mass. Apart from pressure systems that sweep down from China, Thailand’s weather is mainly characterized by the tropical monsoon.

Monsoons in Thailand begin after Songkran, or Thai new year in April. Generally, caused by the southwest monsoon sweeping out of the Indian Ocean with moist air heading in a north-easterly direction across Thailand from the Andaman Sea, rising warm air over the southeast Asian land.

The intensity of the monsoon season varies from one location to another in Thailand. Rainfall can last from fifteen minutes to a few hours during the day. However, in most cases, the rain could be over within 15 minutes in the morning or evening.

Floods are widespread during this season in Thailand. If you plan to go to Thailand during this time, get ready to wade through the floodwater.


The rainy season starts in June or early July and reaches its peak in September. The rain begins with notable overnight dumps before increasing to more regular rains almost daily in July and August.


The rainy period in this region lasts longer than Bangkok. It usually starts in May and continues until November, with July and August being the wettest months.


The shortest rainy period stretches from May to October, but 80% usually falls in August and September. But some islands like Koh Chang and those off the coast of Trat province can be very wet during this season, which is usually around May to October.


The breathtaking landscapes of Koh Samui, Koh Phangan, and Koh Tao in the gulf of Thailand attract tourists all year round. However, these islands have their own seasonal weather patterns. The monsoon season does not hit the Gulf Islands until later in the year.

The rains generally arrive from October to December with peaks in November.

Of course, nothing is set in stone, especially as global warming takes over, however the information above will give you a fairly good indication.
