Weather in Thailand in January

January in Thailand is a hot month. Plan the serious walking for morning. The rest of the day wants shade and a slower pace.

A country pin in January is a warning: one region of Thailand will not match another. Use a city page if you already know where you are going. Compared with April and December, January sits in the middle of Thailand's year.

What to expect

Daytime

Hot days in Thailand. Ruins, markets and hills are a morning job. Midday sightseeing is how people remember January for the wrong reason.

Nights stay warm. Air-con, if you can get it, is part of the brief. A jumper for January in Thailand is almost always a waste of bag space.

Rain

Rain is not the story in Thailand in January. Pack for sun. A shower would be news, not a plan.

Do not build the trip around weather windows. Build it around shade if it is hot, and around getting outside if it is not.

Evening

Evenings stay warm.

What to pack

  • Sun protection
