Weather in Thailand in December
December 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 December is a warning: one region of Thailand will not match another. Use a city page if you already know where you are going. December is the cold side of the year in Thailand. Pack for that, not for a leftover summer photo.

What to expect
Daytime
Hot days in Thailand. Ruins, markets and hills are a morning job. Midday sightseeing is how people remember December for the wrong reason.
Nights stay warm. Air-con, if you can get it, is part of the brief. A jumper for December in Thailand is almost always a waste of bag space.
Rain
Rain is not the story in Thailand in December. 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
