Thailand Weather in August: An Overview

Thailand’s weather in August is dominated by the southwest monsoon, making it the wettest month across most regions.

It sees humidity levels of 75 - 85% and temperatures at 28 - 32 degrees C (82 - 90 degrees F) by day and 24 - 26 degrees C (75 - 79 degrees F) at night.

Rain varies significantly by region, with some areas seeing over 200mm per month. The rain comes in bursts during evenings and afternoons, leaving several hours of daily sun.

National Climate Trends

August is the peak of monsoon season, which sees thunderstorms reported every 15 - 20 days a month, usually lasting for 1 - 3 hours.

Also, in the afternoons and early evenings, between 2 PM and 8 PM, it rains the most. In the mornings, it is usually still bright out. Sea conditions can be at their worst along the Andaman coast with waves 2 to 3 meters high.

What to Expect as a Traveller

Thailand’s weather in August is very unpredictable; it requires a flexible plan and patience. Rain often disrupts outdoor plans, but also brings out the opportunities for indoor attractions, including temples, museums and shopping centres.

At this time, there’s a drop in tourist numbers, which in turn results in shorter lines and more authentic experiences. Some outdoor attractions may be closed or have reduced hours during severe weather.

Regional Weather Breakdown

Bangkok and Central Thailand

Bangkok reports 150 - 200mm of rain per month, at which time the urban heat index goes up before there’s some relief in the early evening. We do see some flood reports in the low areas, but the BTS and MRT systems run as usual. Central Thailand’s rice fields are at their prettiest, just that some of the rural roads may turn rough.

Northern Thailand (Chiang Mai, Chiang Rai)

In the north, rain is between 150 - 170mm with temperatures at 28 - 30°. In the mountains, one can find mystical settings of morning mist and low clouds. Trekking may be restricted, but cultural sites are still accessible.

Southern Thailand (Phuket, Krabi, Koh Samui)

In June, the Andaman coast (Phuket, Krabi) reports over 250mm of rain, which in turn causes rough seas and a decline in water-based activities. But at the same time, the Gulf islands like Koh Samui are in the midst of their dry season, which is a very good alternative to the rest of Thailand at this time of the year.

Things to Do in Thailand in August

Despite the rainy weather, one can always seek to learn more about the different aspects of Thai culture while making the most of Thailand’s weather in August. Cooking classes for Thai food are very popular in the afternoons, as well as spa services, which also see an increase in their numbers and availability. At the temples, the architecture is at its best after the rains, and the few tourists mean you have the place to yourself. Indoor malls and night markets are the social spots. Chatuchak, which is open all year round, even in the rain, reports heavy foot traffic. Similarly, MBK Centre and Siam Paragon have a wide array of products. In 2025, August 12th is Mother’s Day, which is a chance to see traditional Thai celebrations. For beach goers, Koh Samui has its dry season in August, the access is at its best, and the sea is calm, ideal for water sports.

Packing Tips for August Travellers

While packing for Thailand weather in August, you need to be smart and versatile, keeping in mind options which protect you from the weather.

Go for synthetics over cotton.
Include many compact umbrellas and lightweight rain jackets for better wind protection than ponchos.
Waterproof phone cases, dry bags for cameras, and portable power banks are a must.
In humid conditions, laundry takes more time, so pack extra clothing.
Also, quick-drying towels and anti-microbial clothing help out with health issues. Medications should be put in waterproof containers.

Travel Tips for the Rainy Season

Flexibility is important to prepare for Thailand’s weather in August. Book into a flexible accommodation package and have backup indoor plans.

Use the local weather apps for the most accurate reports and get that Thailand Digital Arrival Card well before you travel to avoid any delays at the airport.

Build in buffers to itineraries, particularly for transport connections. For weather-related cancellations, travel insurance is a must. Hotel staff can prove very useful for information on activities and alternatives during the rain.

Visa & Entry Requirements

Indian travellers benefit from visa-free entry for 60-day stays at any time of the year. The Thailand Digital Arrival Card has made it easier, especially to avoid weather-related delays at the airport.

For stays which require a visa beyond those 60 days, make sure your photos meet the Thailand visa photo size requirements and apply well in advance to account for possible weather-related processing delays.

Store digital copies of documents in the cloud storage; physical documents are damaged by humidity and water.
