Thailand

What's the weather like in Thailand in July?

The location of Thailand just to the north of the equator gives most of the country a tropical climate. This means it’s hot and humid in July, although there’s differences in the weather depending on which part of the country you’re heading to.

Regional variations

There’s not much difference in temperature through the year in south and central Thailand, while you'll get more rain in the largely mountainous north. Two monsoon seasons dictate the country’s weather, with the north eastern season running from November to April, and the south western from May to October. The former has drier weather than the latter, which comes in from the Indian Ocean and brings warm, humid and cloudy air.

Averages

In popular Koh Samui the average high’s 32ºC in July, and things stay nice and warm for you in the evening, only dropping to 24ºC at night. At 29ºC, the sea’s also nice and warm and perfect for lounging around in, while humidity’s very high. There’s 120mm of rain over nine days, and you can expect six hours of sunshine from the 13 hours of daylight each day. Look after yourself in the sun with plenty of sun cream as UV levels will be extreme. Sunset’s around 6.45pm in July.
