Bangkok and Central Thailand

The average temperature in Bangkok reaches about 30°C (86°F), making for hot days despite the rain.

Rainfall in Bangkok and Central Thailand will increase slightly in August compared to July. Since frequent showers are expected in August, indoor activities are more advisable than outdoor ones.

Northern Thailand

In August, Northern Thailand will receive the most rainfall of the year, especially in Chiang Mai. Heavy downpours with strong winds are expected; however, the rainy weather also helps cool down temperatures in Chiang Mai.

The average temperature in Chiang Mai in August goes up to 27°C (80°F). Chiang Rai shares similar weather as Chiang Mai.

Southern Islands

Most of the southern islands experience monsoonal weather during August. The tropical monsoons bring heavy rainfall, especially in Koh Chang.

The average precipitation there reaches 543 mm (21 in). Phuket, Krabi, Koh Phi Phi, Koh Lanta, Similan Islands, and Trang Islands also experience varying levels of heavy rainfall.

However, the east coasts of Koh Samui, Koh Pha-ngan, and Koh Tao are relatively well protected from the southwest monsoons. If you are looking for an island on which you can spend your family holiday, these are ideal choices.

Why Visit Thailand in August

If you don’t mind a bit of rain, August can be a great time to visit Thailand. The rains keep many people from traveling, so you can enjoy scenic spots and quiet beaches without the crowds.

The frequent rainfall makes forests lush and green and waterfalls full and powerful. So, it is the best time to explore the countryside and some of the forest parks.

Another reason is that August is the shoulder season. A trip to Thailand in this period can be cost-effective.
