Thailand in December
Weather, where to go and what is on — then plan the whole trip, door to door.
The weather in December
Cool, dry and sunny in most of the country — peak season, so book early, especially around Christmas and New Year. The Gulf islands can still be rainy early in the month.
A general pattern, not a forecast: weather changes from year to year, and festivals that follow the moon move by a few weeks.
