    Thailand weather January

    What’s the weather like in Thailand in January?

    Thailand’s just to the north of the equator, which means most of the country has tropical weather and warm temperatures all year round. January’s one of the coolest months of the year, although the temperatures you'll have are only a bit lower than the hottest months. If you're going at this time you'll be in the north eastern monsoon season, which has less rain than the south western monsoon which runs from May to October. It’s warmer, cloudier and more humid in those months. When it does rain in January, it’s usually only for a short time.

    Averages

    Koh Samui’s one of Thailand’s most iconic islands, and has an average high of 29ºC in January. You'll still be nice and warm in the evenings as this only drops to 22ºC. The sea temperature is a warm 28ºC, which is perfect for swimming, while humidity’s high. There’s 123mm of rain over ten days, and you can expect seven hours of sunshine from the 12 hours of daylight each day. UV levels will be extremely high so bring plenty of sun cream. The sun goes down at around 6.15pm for much of the month.
