Where to go to in Thailand in August? Because it is the rainy season, most parts of the country experience heavy rain in August. And flooding can be a problem in Bangkok. So you might have to set aside time for indoor activities. However, you can expect discounts at hotels and resorts – if you don’t mind the rain.

Thailand Weather in August
How is the weather in Thailand in August? Generally speaking, August is considered a poor month to visit Thailand, with lots of rain across much of the country. However, the temperature in August in Thailand is a bit cooler (but more humid) than other months.
Regarding Bangkok, August is one of the rainiest months of the year. And flooding can be a problem. While it rains in Bangkok an average of 20 days in August, that doesn’t mean it rains all day. But there can be the occasional torrential cloudburst.
The average high temperature in Bangkok in August is 33 degree Celsius, or 91 degrees Fahrenheit. And the average low temperature in August is 26 degrees Celsius, or 79 degrees Fahrenheit.
If you are planning to visit other parts of Thailand in August, rains are heaviest in Chiang Mai. And the same goes for the rest of Northern Thailand. Other popular tourists destinations with almost daily rain in August include Khao Lak, Krabi, and Phuket.
If you want to avoid the rain, Cha Am, Hua Hin, Khanon, Koh Phan Ngan, and Koh Samui tend to experience lots of sunshine in August. If you’re after sunshine, focus on the East Coast and avoid the West Coast!
