1. What is the weather like in August? 

August is the rainy season in parts of Thailand, particularly the north and center, with heavy rains and high humidity. Flooding is possible, but it does not occur on a continuous basis; downpours are usually brief and occur in the afternoon or evening. Southern islands like as Phuket and Koh Samui frequently enjoy better weather.

If you don't mind some rain and want to avoid crowds, August can be a terrific time to visit—just make sure you have backup plans.

• Bangkok and Central Thailand

The average temperature in Bangkok is around 30°C in August, making the days warm despite the rain. Streets can flood after heavy rains. The surrounding areas also experience significant rainfall, mainly in the morning and late afternoon.

• Chiang Mai and Northern Thailand

The north receives the most rain of the year in August, similar to September. Chiang Mai sees about 20 rainy days per month. It can even be more, especially closer to the mountains. It's better to say Chiang Mai has very few completely rain-free days in August. Rain falls frequently, especially near the mountains, but it cools the weather to around 26°C and makes the area lush and verdant.

• Southern Thailand

Most southern islands experience a monsoon in August. Beach enthusiasts will find better conditions on the Gulf of Thailand coast. Places like Hua Hin, Ko Samui, Ko Pha Ngan, and Ko Tao enjoy many sunny hours and lower precipitation levels than the Andaman Coast.

The first half of August is particularly favorable for a beach stay on the Gulf Coast. Pattaya, Rayong, and Ko Samet are good options for beach vacations in August. Further east, Ko Chang is one of the wettest places in Thailand in August and is not ideal for visiting at this time.

1.2 Thailand's August 2025: Monsoon season in full swing!

August 2025 in Thailand is set to be a splash! It’s officially the monsoon’s favorite playground, so expect everything from drizzles to dramatic downpours.
