Remember:
The climate in Thailand in august ranges from good to very bad depending on the region and city.
Concerning the climate in Thailand throughout August, keep in mind that raincoats are more important than ever, as the monsoon is at its peak in practically the whole country. Always high, temperatures contribute to make the atmosphere oppressive. For a holiday stay, the seaside represents the best option; The Gulf of Thailand and its southern islands are preferable because the climate in Phuket and the coast of the Andaman Sea is still very rainy this month.
Bangkok and Central Thailand in August
The capital throughout August remains characterized by frequent showers however, a new moisture is also rising. The floods can be spectacular in Bangkok as well as in the central provinces. On the thermometer, expect 24-25 ° C at night but up to 33° C during the day, with the consequence of making the already very humid air even heavier.
Eastern Thailand in August
Even if it does not rain every day and the sun rises, the Center - especially Trat Province and Koh Chang - remains the wettest area of Thailand. The average temperature does not decrease noticeably; for a truly drier August and a higher sunshine, it is best to turn to Pattaya.
Northern Thailand in August
Compared with July, the rains are increasing and often creating floods or landslides. It rains practically every day and, due to a high temperature (31° C to 33° C daily ), the air is very choking and even uncomfortable in Chiang Rai and Chiang Mai.
Northeast Thailand in August
Here too the wet season is at its peak. The climate in August in northeastern Thailand does not differ from the northern one except for more abundant rains near the Laotian border. The average daily temperature is about 28° C with peaks at 32° C. The air remains suffocating due to a very high humidity level. Air conditioning and fans are recommended!
Southeast Thailand in August
The southeast in the Gulf of Thailand receives ten times less rain than the northeast coast, making the islands of Koh Samui, Koh Phangan and Koh Tao rather inviting compared to those of the Andaman Sea. The air, however, is rather suffocating due to a maximum temperature of 31-33° C. The water keeps its temperature in July, at about 28° C.
Southwestern Thailand in August
Although in the middle of the wet season, the southwest coast is experiencing a significant decrease in showers. On the other hand, Koh Lanta and Phuket still enjoy very high temperatures (average of 29° C) and therefore the air is at best, stifling. Fortunately, a breeze coming from the west just somewhat refreshes the atmosphere. August offers cheap vacation plans if one does not fear the rain - and it does not rain every day!
