August Travel Guide for Southeast Asia

Here are our recommendations for where to go and what to do during August in Southeast Asia.

Thailand

In the north rainy season is in full effect but will mostly consist of rain each day during mid to late afternoon downpours than often last only an hour or so before it starts to dry out again. Night-time storms also happen and can provide incredible light shows. Temperatures are in the low 30’s/86-91°F and pleasant at night.

Rainy season in Bangkok with average temperatures around 29°C/84°F and 5 or 6 hours of sunshine a day. Torrential showers are common however which can sometimes lead to flooding.

On Koh Samui the temperatures increase a little but so does rainfall and the frequency and duration of rainfall will increase throughout the month.

On the Andaman Sea coast the south west monsoon hits the area from June to October when rainfall can hit highs of 350mm in a month. It’s not all bad though as the rain tends to fall in the late afternoon or early evening and the rest of the day could be bathed in hot sunshine as temperatures remain in the 30’s most of the day.
