August in Thailand is the low season and there are advantages to visiting at this quieter time of year. Tourist attractions are less crowded and, as with the other low season months, there are often enticing deals on hotels and internal flights. Although the weather can be variable, you will still be able to enjoy warm temperatures with August an excellent time to explore Thailand beyond the beach.

August weather
August is the rainy season in Thailand so you should expect to see some wet weather during your stay. It doesn’t rain all day every day and in most regions of the country you can still expect to see plenty of good weather too. Tropical downpours can be intense in August, but are usually triggered later in the afternoon or evening.
Location | Avg. Min. Temp. (C) | Avg. Max. Temp. (C) | Avg. Rainfall (mm) |
Bangkok | 24 | 32 | 187 |
Chiang Mai | 23 | 31 | 227 |
Ko Samui | 25 | 32 | 106 |
Krabi | 25 | 31 | 266 |
Pattaya | 26 | 31 | 91 |
Phuket | 25 | 31 | 272 |
Where to go in August
If you are keen to hit the beach, the Gulf Coast of Thailand is the best option. Locations including Chumphon, Hua Hin, Khanom, Ko Samui, Ko Pha Ngan and Ko Tao all see lots of hours of sunshine and much lower levels of rainfall compared to the opposite Andaman Coast. This is especially true in the first half of August making the Gulf Coast ideal for an August beach break. Over on the east coast, Pattaya, Rayong and Ko Samet are also good options for a beach holiday in August. Heading further east still, Ko Chang is less sheltered from the effects of the monsoon and is one of the wettest places in Thailand during August. As much as we love the island, August is not the best time to visit Ko Chang!

If you are staying in one of Thailand’s main cities such as Bangkok or Chiang Mai, temporary flash flooding can sometimes occur. The situation usually resolves itself relatively quickly once the rain stops and begins to drain away. It can be quite an experience, but the locals take it in their stride so just follow their lead. In the bigger cities there is plenty to see and do if the rains do come down, so don’t let it put you off visiting.
August events & festivals
The main event in Thailand in August is the birthday of Queen Sirikit on August 12. The day is a public holiday in Thailand and also celebrated as Mother’s Day (Wan Mae). Hotels and restaurants often put on special Mother’s Day promotions that last throughout the month, so keep an eye out for them if you are visiting Thailand in August.
