Travelling in Thailand during Rainy Season

We have all heard nightmare stories about traveling in tropical countries during the rainy season. However, even though the rainy season can be difficult to plan for, there are still plenty of tips and tricks that can help you have an amazing experience.

In this article, we will explain what to expect when traveling in Thailand during the rainy season, as well as the best destinations and things to do to guarantee that you still have an amazing experience, no matter the weather.

Thailand During the Rainy Season

The rainy season in Thailand can greatly affect the travel plans of visitors due to its unpredictability. Often during this time of year, it will rain at least 9 out of every 10 days. These rains usually are very heavy downpours with thunder and lightning.

Downpours often start in the late afternoons or early evenings, but sometimes it will also rain in the mornings. When it isn’t raining, the skies are overcast and the air is very humid.

These heavy downpours can sometimes cause flooding in lower areas and valleys, but the floods typically disappear by the next day.

Although these conditions sound unbearable, it is actually still possible to travel in Thailand at this time, as long as you come prepared with an umbrella, poncho, and waterproof shoes, or sandals.

The truth is, if you travel in Thailand during the rainy season, you are going to get wet, but you can still have a great time by scheduling activities in the mornings and understanding that your plans may be interrupted by the weather.

When is the Rainy Season?

The rainy season in Thailand typically takes place from July to October. Sometimes the months of May and June will also see some extra rains as they lead into the official monsoon season.

During the rainy season, the high will be around 89º F (32º C) and the daily low around 78º F (25º C). April and May are the hottest months of the year in Thailand. The months that typically get the most rainfall are August and September.

During the rainy season in Thailand, the seas are typically very rough, and for beachgoers swimming and watersports can sometimes be dangerous due to generally large waves and frequent storms.

What is the Monsoon?

Although you will typically hear the terms rainy season and monsoon season used interchangeably, monsoon season actually means a period of time when the winds bring moisture from the Indian Ocean to the southeast Asian subcontinent. These winds cause the humid and wet weather that we associate with the rainy season and also cause some of the tropical storms that happen at this time.

Cost of Traveling

Traveling in Thailand during the rainy season is much cheaper than traveling during the high season. The number one reason for this is simply because there are fewer travelers in the country at that time. Many businesses therefore offer discounts.

Depending on where you visit and which hotels you choose, it is possible to get deals that are as much as 30% cheaper than during high season.

Rainy Season and Your Travel Plans

It is not easy to ignore the effect that the rains will have on your travel plans if you choose to visit during the rainy season. If you want to visit Thailand because you want to take part in outdoor activities such as trekking, visiting elephant sanctuaries, or sunbathing on the beach, then it would probably be best to visit during high season.

However, there are plenty of activities that travelers can do during the rainy season. Many of Thailand’s famous cities and temples can still be visited in the rain. Also, Thailand's delicious food, famous markets, malls, and vibrant culture can all still be experienced with careful planning and flexible schedules.

Best Destinations in Rainy Weather

Although the rainy season will affect your travel plans, you can still have an amazing time by visiting great places and picking exciting experiences that can't be ruined by the rain.

Below we have included some information about some of our favorite rainy season destinations and activities.


In Bangkok, it will rain almost every day during the rainy season, although it rarely rains all day. This means that many activities can be planned around the weather. However, it is important to note that during the rainy season, travelers won't be able to do the classic floating market tours.

There are many indoor activities available in Bangkok, including visiting shopping complexes, aquariums, temples, and museums. Bangkok's shopping malls are particularly popular during this time of year and can be reached using the metro system, making it easier to avoid traffic jams due to weather.

Chiang Mai and Chiang Rai

Because Chiang Mai and Chiang Rai are much further north than Bangkok, these cities are typically much dryer, although they are still affected by the rainy season. While visiting these cities in the rainy season, you will still experience the downpours but they usually occur for only a few hours in the late afternoon.

This often still makes it possible for travelers to explore the cities by scheduling temple visits during the mornings or early afternoons.

When it is raining, the city still offers plenty of things to do such as shopping, getting famous Chiang Mai massages, taking a cooking class, and visiting museums.


In Phuket, the rainy season is a little different from the rest of Thailand. Typically, Phuket experiences the most rains during the months of September and October. If you visit during the other months of the wet season, you will probably experience some rains, but most days will have good weather. 

Even on clear days, there will be strong winds which make the waters too rough for swimming.

When it does rain, Phuket has lots of different options to keep visitors entertained, including some good museums like the Tin Mining Museum, the Thai Hua History Museum, and the Seashell Museum. There is also an aquarium on the island that is pretty cheap and offers a lot to see.

Koh Samui

Similar to Phuket, Koh Samui is a good place to visit during the rainy season because although it won't be dry, it certainly won't get as much rain as the rest of the country. During the rainy season, Koh Samui's weather won't be perfect and you will likely see overcast skies and feel the humidity, but the beaches will be quiet and the restaurants will be empty.

Just like Phuket, during this time the sea in Koh Samui will be very rough due to the strong winds, so swimming and watersports aren't recommended. The boat ride to the island will likely be very bumpy as well.
