They don't say Thailand has a monsoon climate without reason! August in Thailand, just sees the rain keep coming. It's not all bad news though, as August marks the peak of the wet season in both northern and northeast Thailand — things will start to dry out from here onwards. In other regions though, the wet season lingers.

Bangkok and Central Thailand

Bangkok in August sees a bit of a hop in the overall rainfall figures, but elsewhere in Central Thailand, while the rain increases a little, it isn't too bad. Temperatures remain very warm — close to identical to those of July. Expect to see street flooding in Bangkok in August — especially after torrential downfalls — we've waded down waist deep sois in Bangkok in August.

Eastern Thailand

The weather on Ko Chang in August is simply ridiculous. Expect rain almost every day and not just a light sprinkle — when we say rain, we mean rain. Not surprisingly, landslides can be a problem. Trat province (where Ko Chang is situated) is the wettest province in Thailand for the entire year.

Northern Thailand

August marks the peak of the wet season in Northern Thailand. Sure the wet season has a few months left in it, but August is the wettest. Expect a little over 20 days of rain in August, more along the Burmese border. Chiang Mai and some other urban centres may some street flooding and, in especially wet years there may be some more general flooding problems and landslides in deforested (ie most) of the north — especially in Phrae, nan and Chiang Rai.

Rainfall and temperature chart for Thailand in August

Northeast Thailand

As with northern Thailand, August marks the peak of the wet season in Thailand. From here onwards the rains start to roll back and the temperatures continue to drop. The provinces to the east, bordering Laos and the Mekong River, see the most rain this time of year.

Southeast Thailand

The temperatures in Southeast Thailand continue to inch south through August. As with the preceding months, the mainland remains a little drier, but in August the prevailing winds swing to the west and the east coast of the islands can be lovely. The east coast of Ko Tao is really quite divine. August and September mark a respite from the rain before it ramps back up in October.

Southwest Thailand

The temperatures edge down slightly, just as the rains continue to increase. The northernmost province on the Andaman Coast, Ranong, sees it's wettest month of the year and that is really saying something as Ranong has the highest rainfall, annually, in all of Thailand. Elsewhere on the west coast the rain isn't so terrible, but August is still in the midst of the wet season here, so you need to expect, and plan for, wet weather.
