Thailand in October
Weather, where to go and what is on — then plan the whole trip, door to door.
The weather in October
The rains ease towards the end of the month and the cool season begins in the north. The Andaman coast reopens for the high season from late October.
A general pattern, not a forecast: weather changes from year to year, and festivals that follow the moon move by a few weeks.
